FOREWORD by Erich Mühlthaler

I still well remember the day in 1990 when I received my copy of the ﬁrst edition of U.S. Submarine Attacks During World War II. I was immediately deeply impressed by the wealth of data that someone had taken the burden to compile. After many years I can truly say that it was this work by John D. Alden which inspired me to start my own research into the ﬁeld of Japanese merchant shipping. During the following years I collected every bit of Western language information that I could ﬁnd about Japanese merchant ships. However, I realized that a thorough and more ﬁnal approach to this subject would deﬁnitely require the study of the Japanese language sources. The Japanese language barrier has always been a major hindrance for any serious Western researcher. To overcome this barrier I made the commitment to study the basics of the Japanese language. It took me several years of difﬁcult study and many headaches until I achieved a good command of reading Japanese text. In 2001 as I was becoming proﬁcient in Japanese, I came across a notice in a naval magazine that mentioned a privately published second edition, now titled United States and Allied Submarine Successes in the Paciﬁc and Far East during World War II. This small notice caused me many sleepless nights until I succeeded in getting one of these rare copies. This volume proved to be a largely revised and expanded edition, including extensive use of highly important material from the Allied

ULTRA signals intelligence agencies and — for the ﬁrst time — invaluable data from more recent Japanese language publications translated by William G. Somerville. Based on this excellent revised edition I intensiﬁed my own investigations, looking for additional Japanese sources. During the ensuing years the main focus of my work has been the investigation of the particulars of every Japanese merchant ship above 200 gross registry tons, including data on construction, technical speciﬁcations, correct spelling of the ship’s name, ship owner(s), army/naval requisitions, wartime movements and ﬁnal fate. In addition I have also created a large database for the many hundreds of smaller and larger vessels captured by the Japanese during the early months of the Paciﬁc War. I am deeply indebted to my Japanese friend Nori-san who has enabled me to obtain many Japanese language publications and other newly published documents. During the last decade there has been a steady increase of new Japanese publications edited by a new generation of Japanese researchers. By far the most important publication is the 12-volume work Senji Nippon Senmeiroku 1937–1950 ( Japanese Wartime Shipping Register) compiled by Japan’s leading merchant shipping expert, Hiroshi Hayashi, published in November 2006 by Senzen Senpaku Kenkyukai (The Old Ship´s Research Group). This gigantic work gives information on about 47,000 ships above 20 grt together with their technical data and war loss 1

Foreword by Erich Mühlthaler information. It was based on all available and existing Japanese ofﬁcial documents and material. To cross-check all listed Japanese ship losses against entries in Submarine Successes and to combine all known data from Western and Japanese sources including results of my 20 years of research I began an intensive and extremely fruitful exchange of correspondence with John D. Alden and Craig R. McDonald. As a result, we have been successful in evaluating and verifying data for most entries in Submarine Successes and also have been able to ﬁll in many gaps in the data, correct several old mistranslations of ship names, and ﬁx other errors mainly originating from early postwar records. Moreover, we have compiled a huge amount of new and additional data otherwise not accessible to most Western researchers.

2 This newly revised edition is the most comprehensive and unique reference work of its kind — the product of more than 30 years of detailed research by the leading expert in the ﬁeld, John Alden. It provides the most extensive and reliable data from all available Western and Japanese sources on American and other Allied submarine successes against Japanese shipping in the Paciﬁc and Indian oceans in any one volume. Without a doubt, John Alden´s monumental and outstanding work will stand as an everlasting tribute to all brave and proud American and other Allied submariners who were ﬁghting for a free world. Burghausen Germany

Erich Mühlthaler, a member of the World Ship Society, has studied all aspects of Japanese merchant shipping during World War II since the mid–1980s, especially data from Japanese language sources.

PREFACE Naval historians of World War II generally credit the United States submarine force with having played a major role in winning the war against Japan by gradually but inexorably picking off the ships that constituted the lifeline between the empire and its far-ﬂung possessions and conquests. Although the major outcomes of the submarine campaign are well known, and many accounts have been published extolling the exploits of particular submarines, no deﬁnitive record of our submarines’ successes has yet been compiled. The problem is inherent in the very nature of undersea warfare. Submarine commanders can seldom observe their attacks closely enough to be certain of the results, let alone identify the ship being attacked. On the other side, the victim of an underwater assault rarely sees its attacker, and may not even be sure whether an explosion was caused by a torpedo or a mine. For these and other related reasons there are many gaps in the record of “who attacked whom” during the war in the Far East. Submarine commanders of all nations claimed many more sinkings than actually occurred, and this was especially the case in the war against Japan. The primary objective of this book is to provide a comprehensive list of all U.S. submarine attacks for which success was claimed (or was later found to have occurred), together with corresponding information on Japanese and other ship losses during the war. In the interest of completeness, the record has been expanded to include the few attacks made by U.S. sub-

marines in the Atlantic, the attacks made by British and Dutch submarines operating in the Paciﬁc and Indian oceans, those made by Soviet submarines late in the war, and casualties caused by mines laid in the Far Eastern areas by U.S. and Allied submarines. Much of the basic information herein was published in 1989 in my book U.S. Submarine Attacks During World War II (Annapolis, MD: Naval Institute). As I noted in the preface to that volume, it was “by no means ... the ﬁnal word on the achievements of U.S. and Allied submarines” during the war. In fact, the objective was to “facilitate the work of future researchers by providing a handy compilation of the data recorded by others, including those entries that have turned out to be false leads in the search for the truth.” Many individuals responded with new data, but the bulk of the information that has been added to this updated listing comes from three sources: originally topsecret ULTRA intelligence information derived from Japanese radio messages intercepted and decrypted during the war; information translated from Japanese publications by William G. Somerville of Lincolnshire, England; and material translated from Japanese and other documents by Erich Mühlthaler of Burghausen, Germany. The ULTRA information and Japanese translations by Somerville resulted in a self-published second edition of approximately 110 copies in 1999. Those two sources of information plus Mühlthaler’s recent additions have added thousands of new details and created this third edition. I have ﬂeshed these out with brief 3

Preface descriptions of the attacks taken directly from submarine patrol reports. The number of reported crew, civilians, or military personnel casualties has been greatly expanded; convoy names have been added. Finally, I have added my personal evaluation of the result of each attack based on the totality of the reported evidence and my assessment of the reliability of the various sources of information. However, I must repeat my earlier disclaimer: This work is still by no means the ﬁnal word on U.S. and Allied submarine successes. Particularly on the

4 Japanese side I am reporting information that has come to me two or three hands removed from the original Japanese-language records. Craig R. McDonald, [email protected], and I will welcome corrections or additions, especially from anyone who has access to primary or archival sources. John D. Alden Commander, USN (Ret.) [email protected]

A DETAILED EXPLANATION OF THE DATA Caution

1. Submarine hull number and name 2. Patrol number 3. Commanding ofﬁcer’s name 4. Month and year 5. Date and hour 6. Submarine’s position 7. Type of target believed attacked 8. Estimated target size 9. Type of attack: torpedo hits and number ﬁred, or gun attack 10. Result claimed: sunk, damaged, or other

Users are reminded that this list contains only attacks that were originally claimed as successful or were later determined to have been successful. Approximately an equal number of unsuccessful attacks are not included. Note that post-war records have shown conclusively that many claimed hits were actually misses or duds; others were based on very weak visual or audio indications and are unsupported by any records discovered to date. The fact that a claim is listed in this book should never be interpreted as evidence of an actual hit. Users are urged to read the following explanatory material before attempting to interpret the records of attacks, which are extremely condensed and use many abbreviations.

The next seven data elements, which appear below the submarine entries, after the attack number, present the attack as reported from the Japanese perspective: 11. Reference Source(s): major ones are noted here, others elsewhere as described in the detailed section 12. Date: usually but not always the same as reported by the submarine 13. Location of attack: this seldom agrees exactly with the position reported by the submarine 14. Type of ship actually attacked 15. Tonnage of ship attacked (gross tons for merchant types, standard displacement tons for regular warships) 16. Name of ship attacked {incorrect or non-valid names are in braces} 17. Damage incurred: sunk; heavy, medium, or light damage; undamaged, etc.

A Brief Explanation of the Data Tables Each attack is presented in 19 data elements, which readers familiar with submarine operations will be able to follow with little difﬁculty. More detailed descriptions of each data element, including the abbreviations and annotations used, will be found later in this section. The ﬁrst 10 data elements, which appear as the top line in each attack record, describe the attack as made by the submarine: 5

A Detailed Explanation of the Data In the bottom line(s), printed in italics, are the following data: 18. Comments: an abbreviated account of the attack as presented in the submarine’s patrol report (PR), followed by details from the speciﬁc sources and comments by the author [in brackets]. 19. Alden Evaluation: Alden’s personal overall evaluation of the attack’s outcome: S for sunk, D for damaged, 0 for not hit, etc. These are followed by symbols for Alden’s estimate of the reliability of the source data. See the detailed section for a full explanation.

Some Cautions War records are replete with cases where submarine commanders mistakenly believed they had sunk ships. Observations made hastily with only a few feet of periscope exposed, or in a chaotic night attack on a milling convoy, are often inaccurate; those based only on explosions heard, the behavior of radar pips, or noises picked up by sonar, are also likely to be unreliable. Many commanders were deceived by premature explosions of their torpedoes. It was even more common for them to overestimate the size of their targets, in part because of the magniﬁcation provided by periscope lenses and also because of the limited opportunity to examine the ship being attacked. Both warships and merchant ships of common types tend to have family resemblances. Tankers, for example, look alike whether large or small; similarly, small warships can look like larger types when viewed under conditions of poor visibility. The ability of U.S. submariners to identify their targets by name was so poor that by 1944 Commander Submarines Paciﬁc told his skippers to stop trying and just use standard tonnage estimates. On the enemy side, ships seldom saw an attacking submarine. In some cases ships sim-

6 ply disappeared, and the cause, location, or time of loss may therefore not have been known accurately. Since submerged submarines during World War II often could not know their position precisely, and ships under attack may not have had time to establish their position accurately, the reported locations of attacks are likely to be only approximate and will seldom agree with the position reported by the attacking submarine. The problem is compounded when sinkings occurred hours or days after the initial damage, or when several submarines attacked ships in the same convoy. Matching particular submarine attacks to speciﬁc ship casualties is therefore imprecise if not impossible in many cases. Another problem results from differences in the amount and quality of information provided by the various sources of data on submarine attacks. Such differences include ship classiﬁcation systems, methods of measuring and reporting tonnage, identiﬁcation of geographic features, the use of different time zones, and others. It will be noted that Japanese sources frequently report two or more different positions or times for a given ship casualty. Such differences can result from different basic records of the event as well as from errors in translation or transcription. Separate reports made by the ship that was hit, its naval escorts, other ships in company, rescue ships, or survivors of sinkings, will almost always vary in detail. The matter of time zones is particularly important. U.S. submarines frequently had their clocks set to different zone times, whereas Japanese sources always use standard “Tokyo time.” Because this tabulation incorporates data from many sources in a necessarily condensed format, users are urged to study carefully the information that follows on the sources as well as the method, conventions, and abbreviations used in presenting the data. In the case of English-language reports of data from Japanese records, errors in the transliteration and interpretation of the Japanese characters are easily made. For example, this has led to confusion

7 in some ship names. If sources disagree signiﬁcantly about one or more facts (ship name, date, etc.) both are shown on a separate line or explained in the comments. Particular attention is invited to the warning by W. G. Somerville that the reliability of the Japanese records translated by him may have been affected by cross-quotation from U.S. and Allied sources. Also note the special section on ULTRA, in which problems inherent in the decryption and translation process are discussed in more detail. In all cases it is important to bear in mind the distinction between data whether reported from U.S. or Japanese sources; the assessment by each side separately of the causes or results of an attack; and the attribution or assignment of credit to a particular submarine, which is a judgment based on comparing information from the attacker to that from the victim. This distinction is especially important in cases involving “wolf pack” attacks by several submarines on Japanese convoys, and in those attributed to mines.

Principal Sources of Data on U.S. Submarine Attacks 1. Patrol reports constitute the original or primary source of data on most attacks as made by U.S. or Allied submarines. These detailed reports by the submarine commanders were the principal basis for assessing the results of attacks during the war. They have been used extensively and often uncritically by the authors of most published histories or accounts of wartime submarine actions. Although there may be some minor slanting in the reports to portray the submarine’s performance in the most favorable light, their descriptions of the actual attacks are the best available. Alden has reviewed almost all U.S. patrol reports, including formerly secret annexes available at the Naval Historical Center, and has examined many in detail where necessary to resolve conﬂicting information from other sources. Such cases include those where Japanese casu-

A Detailed Explanation of the Data alties apparently were caused by attacks judged unsuccessful by the U.S. evaluators, those where submarines were given ofﬁcial credit for sinking “Unknown Marus,” and those where two or more submarines made attacks on the same ships or convoys. Where submarines were lost on patrol, some information may have been available to the authorities from radio messages sent before the submarine was lost; events seen or heard by other submarines, surface ships, or aircraft; information discovered by intelligence methods; inferences based on the last known position or assigned patrol area of the submarine; or reports by survivors. 2. During the war the Submarine Operations Research Group (SORG), under Commander Submarines, Paciﬁc (ComSubPac), listed and assessed all reported submarine attacks. It took into account the commanding ofﬁcers’ patrol reports, the comments of higher commanders in their endorsements to the reports, and the limited information available from radio trafﬁc with submarines that were lost or other sources. SORG tabulations by date and hour of attack and also by boat and patrol number were used. These were classiﬁed secret until well after the war. It is apparent that little intelligence information was made available to SORG. So-called ULTRA information obtained from decrypted Japanese messages was not provided. Data entries in SORG are: date (month/day/year), hour, light condition, operational command (headquarters), latitude, longitude, type of approach and attack, torpedo model, torpedoes ﬁred, hits, target type, result, estimated target tonnage, submarine hull number, and patrol number. The “result” data represents SORG’s assessment of the success of the attack with, in most cases, no knowledge of the identity of the actual target. SORG’s assessments of sinkings and damage, as well as those of target tonnage, almost always agree with those of the operational commanders. Unfortunately, they are greatly overestimated in comparison with postwar analyses. Although this was known during

A Detailed Explanation of the Data the war to the few people who had knowledge of ULTRA ﬁndings, it was not revealed lest the Japanese ﬁnd out that their codes were being broken. The SORG assessments, however, have been given certain credence by being cited in the U.S. government publication United States Submarine Losses, World War II (hereafter cited as USSL). Despite its limitations, the SORG compilation is a generally accurate summary of the data in patrol reports; as such it is handier to work with than the original patrol reports. In addition to the ULTRA problem, SORG’s assignment of partial credit to two or more submarines in certain cases has proven to be incorrect. Another shortcoming is that SORG gives the time of attack rounded off to the nearest hour, and more seriously, shows the time as given in the patrol report without consideration of the zone time being used. Since Japanese reports all used Tokyo time, submarine time reported in a different zone must be corrected before the reports can be compared. See further discussion of zone times under the description of the date/hour. 3. U.S. and Allied submarines laid mine ﬁelds in Japanese waters and these are known to have sunk or damaged shipping. A number of sinkings that the Japanese attributed to submarines were probably caused by mines. Because such sinkings usually occurred some time after the mines were laid and seldom can be pinpointed to the reported location of the mine ﬁeld, they are very difﬁcult to attribute to speciﬁc submarines. The problem is compounded because mines were often laid in the same or nearby areas by Allied aircraft or even by the Japanese themselves. Casualties that have been ofﬁcially attributed to, or appear likely to have been caused by, submarine-laid mines are included in the Mine Attacks section.

Principal British Data Sources 1. Most patrol reports by British submarines were not readily available for this book.

8 Starting in September 1944, a number of British submarines operated out of Fremantle, Australia, and Subic Bay, the Philippines, under U.S. operational control. Reports of these patrols were found in the Operational Archives at the Naval Historical Center, but they may now have been transferred to the National Archives. 2. The ofﬁcial record of British submarine attacks is Naval Staff History Second World War, Submarines, Vol. 3, Operations in Far Eastern Waters, published in 1956 and referred to hereafter as the British Staff History or BSH. This volume contains summaries of each patrol (including those made by Dutch submarines when under British operational control), data on mine ﬁelds, and an assessment of ships sunk. Much of the information (especially on small craft attacked) is given only in general terms; in some cases not even dates are provided. The summaries of patrols from the Netherlands East Indies and Ceylon from 1941 to 1943 are reasonably descriptive, but those from Ceylon in 1944 and 1945 are quite sketchy. Patrols from Australia and Subic Bay are generally reported in more detail. The 6th patrol of HMS Storm was inadvertently omitted. There are also some errors in the assessments, which is not surprising given the early publication date. 3. Some supplementary information on patrols from Ceylon was found in the so-called “Success Book,” a handwritten record kept during the war, in which attacks made by most of the British submarines are recorded. These entries correlate fairly well with the information in BSH, but the two records are not entirely consistent. The “Success Book” does, however, give dates for some attacks that are not dated in BSH. The book is held by the Royal Submarine Naval Museum in Gosport, England.

Principal Dutch Data Sources Dutch submarines operated under several command organizations. After a few patrols under direct Dutch control in early December

9 1941, most of the Dutch boats in the Far East were placed under British operational control and based in Ceylon until shifting to Fremantle in 1944. The patrols of these boats are summarized in the British staff history (BSH). Reports for the Dutch patrols made from Australia after they came under American operational control were available at the Naval Historical Center. The oldest Dutch boats did not go to Ceylon but escaped directly to Australia. The KXII, K-XIV, and K-XV conducted special missions from Fremantle under the U.S./Netherlands Forces Intelligence Service (NEFIS); these are not included in BSH. The closest thing to an ofﬁcial listing of Dutch submarine attacks appears in the publication De Nederlandse Onderzeedienst 1906–1966, hereafter referred to as DNO. This includes limited information on the few attacks made before the boats were placed under British operational control and those made under NEFIS; otherwise it is in good agreement with the British records. There are a few errors in the attributions of credit.

Principal Sources of Data on Japanese Ship Casualties 1. Japanese war records were long reputed to be incomplete because of wartime losses, deliberate destruction, and postwar confusion. Records seized by the United States received little attention after the war and were returned to Japan in a disorganized condition. Accordingly, the available original records were largely inaccessible for many years, especially to persons unable to read them in the original Japanese. The English-language compilations listed below do not include references to the speciﬁc Japanese archival records and must therefore be accepted more or less on faith. This is particularly unfortunate when separate compilations are in conﬂict, which is the case rather frequently. In some cases it is impossible to judge which source is more likely to be correct. In order to provide a cross-reference of the major

A Detailed Explanation of the Data data sources, the data tables list the major differences, including those believed to be erroneous. 2. One of the most useful primary sources is the radio messages sent by ships under attack. In many cases, these were intercepted, decrypted, and translated in whole or in part by the super-secret Allied operations commonly known as ULTRA or Magic. Unfortunately, the U.S. translations are often incomplete and subject to garbles in interception and errors in translation or interpretation. (See the section headed ULTRA for more information on these problems.) However many of the original messages are in the Japanese archives and are probably the basis for some of the recent Japaneselanguage compilations. Written combat and casualty reports submitted by the ships involved in submarine attacks would be other primary sources. 3. A semi-ofﬁcial English-language tabulation of Japanese ships sunk or damaged was prepared by Japanese researchers for the U.S. Far East Command in 1952. It received limited publication as a monograph titled The Imperial Japanese Navy in World War II, hereafter abbreviated as IJN. This was for many years the most comprehensive list of data on Japanese ship casualties, especially damages short of sinking or total loss. IJN gives data for the date, name of vessel, type, gross tonnage (for noncombatants only), place of loss, cause, and extent of damage. The ship casualties are reported in monthly lists accompanied by charts showing the approximate location of most casualties. In a few cases the charts do not agree with the data in the tables. There are quite a few errors in IJN, typographical or due to misreading of the original records used, which are not identiﬁed. 4. The German naval researchers Jentschura, Jung, and Mickel in 1970 published Die Japanischen Kriegsschiffe, 1869–1945 a major work based on information gathered by the late German naval historian Erich Groner and Shizuo Fukui, a Japanese naval constructor. This was translated into English in 1977 as

A Detailed Explanation of the Data Warships of the Imperial Japanese Navy, 1869– 1945, hereafter referred to as WIJN. The book covers those ships that were part of the Japanese Navy, including a large number of requisitioned and converted merchant ships. It also has a separate listing of standardized merchant types built in war programs. Information on ship sinkings appears to have been provided by Fukui from original records or derived from other published sources. There is very little information on casualties resulting in damage only. 5. William G. Somerville of Lincolnshire, England, translated material from a variety of Japanese publications. Although the authors have not seen the actual publications and could not read them in any case, we are conﬁdent that his translations are reliable. His sources are identiﬁed as WS1, etc., in the data tables, and a complete list will be found in a later section. Neither he nor the authors can attest to the accuracy of the Japanese information. Much of the detail about the attacks can only have come from Japanese primary sources or archival records. However, the Japanese authors have apparently derived some of their information from published U.S. accounts, including the names of the submarines involved in certain attacks and possibly other details such as times and positions. Therefore Somerville warns that because “Allied and Japanese records have become somewhat intermingled ... cross-quoting will lead to the impression that one source conﬁrms another, when in fact they are from the same original source.” 6. Roger W. Allan, a researcher then living in Japan, provided considerable information from 1986 to 1988 for the original issue of U.S. Submarine Attacks During World War II based on various unpublished Japanese sources not available in the United States. Allan’s whereabouts are unknown, and his information has been largely superseded by data from Japanese books and periodicals translated by Somerville and Mühlthaler. 7. TROMs, or Tabular Record of Movements, of Japanese warships are being compiled

10 and posted on the website www.combinedﬂeet. com (also listed as Nihon Kaigun or Imperial Japanese Fleet.) New material and revisions are being added constantly. The site is run by Jon Parshall with input from many other researchers. TROMs for major classes of Japanese ships are being posted on the website by the following individuals: Battleships (“Senkan”) by Robert Hackett and Sander Kingsepp Cruisers (“Junyokan”) also by Hackett and Kingsepp Submarines (“Sensuikan”) also by Hackett and Kingsepp Auxiliaries (“Tokusetsu Kansen”) by Hackett, Kingsepp, and Peter Cundall Carriers (“Kido Butai”) by Anthony Tully Destroyers and torpedo boats (“Long Lancers”) by Allyn D. Nevitt 8. In March 2008 we were contacted by Erich Mühlthaler, a German historian and researcher specializing in the wartime operations of Japanese merchant ships. Mühlthaler has an extensive library including more than 60 Japanese-language books about merchant shipping and convoys, as well as others in Dutch, French, and Chinese. From these he has generously translated extracts pertaining to U.S. and Allied submarine attacks. In particular, he brought to our attention a major new source of data, the 11-volume work Senji Nippon Senmeiroku (Wartime Japanese Shipping Register) by Hiroshi Hayashi, published in a very limited edition in November 2005. This monumental work covers over 26,000 Japanese ships of 20 or more gross registered tons (GRT)— essentially all that existed from 1937 to 1951. It is based upon all available ofﬁcial and other data, including the very scarce ofﬁcial shipping registers (Nippon Senmeiroku) for the wartime years. Data entries include each ship’s ofﬁcial registry number, radio call sign, name, former name and ﬂag of captured ships, ﬁnal registered tonnage, type at time of loss, date and agent of loss, damage, position (latitude-longitude or

11 geographic location or both), number of people killed (crew, shipboard gunners or armed guards, troops, and passengers), and the exact dates when requisitioned or chartered by the Japanese army (IJA) or navy (IJN). Although the data tables do not include the colorful descriptions of attacks provided by other publications, they have enabled us to identify scores of vessels too small to have been included in any previous sources and to be much more speciﬁc about the actual status of the ships at the time of the attacks. In particular, Senji Nippon Senmeiroku gives the Romanized reading of the Japanese characters of the ship’s name. Mühlthaler has made a special in-depth study of Japanese ship names, which often have been confusing to translators. “Meaning and translation of ship names is a science of its own,” he explains. “Many Japanese names have special readings referring to old shrines, temples, geographical locations, ancient terms and much, much more. Furthermore many shipping companies had their own special naming patterns.” Mühlthaler’s special knowledge has enabled us to resolve most of the uncertainty regarding a ship’s correct name that was evident in the previous editions of this book.

Attribution of Credit 1. Immediately after the war, the Joint Army-Navy Assessment Committee published an assessment of Japanese war losses (sinkings only) in the report hereafter referred to as JANAC. To date, this has been the only ofﬁcial U.S. effort to attribute Japanese losses to speciﬁc agents. The main tables in JANAC contain entries for date, name of vessel, type of vessel, standard tonnage, location, ﬂag of agent, type of agent (submarine, surface warship, aircraft, mine, or marine casualty), and assessment (sunk or probably sunk). The JANAC tables are limited to regular Japanese warships and those merchant ships of 500 or more gross tons that were believed to have been sunk; they do not list any ships that were assessed as damaged short

A Detailed Explanation of the Data of sinking, and they omit most of the smaller merchant-type craft that were converted by the navy into gunboats, submarine chasers, minesweepers, or other warship types. Speciﬁc original source documents are not cited or described, and most of the records used were reportedly packed up and returned to Japan after the assessment was completed. In spite of their limitations and some known errors, JANAC data are widely cited, even in recent publications, because no later or more complete ofﬁcial assessment exists. The minutes of the JANAC deliberations were originally classiﬁed secret but have been declassiﬁed and are available to researchers. They show that the committee met beginning on 15 February 1943 and continued working until 23 January 1947. Some of the early assessments were apparently based entirely on a submarine’s report; these account for the credits of “Unknown Maru” to certain subs. When a sinking was claimed, a serial number was assigned to that case and later matched with information from other sources. It is very difﬁcult to trace a case through the minutes of later meetings; some early cases were reassessed and changed, and others were never resolved. As the war progressed, an increasing amount of intelligence information was provided to the committee, some of which clearly came from ULTRA intercepts. The JANAC assessments are therefore a mixed bag: while largely correct, they contain errors and omissions, some of which are noted in our data tables. JANAC does not identify the speciﬁc ships or units responsible for the sinkings, except for a special appendix listing the sinkings for each U.S. submarine by name. It is possible in most cases to identify the speciﬁc attack being credited by referring to the latitude and longitude given in the boat’s patrol report. The JANAC listings include only a few ships sunk by mines laid by submarines, and none of the submarines are individually identiﬁed. German and Italian ships sunk in the Paciﬁc and Indian Ocean theaters are not included, nor are Allied or neutral ships sunk by mistake. The listings for

A Detailed Explanation of the Data individual U.S. submarines do not include credit for ships sunk by mines or partial credit for those attributed to two or more agents. The latter appear in special tables at the end of JANAC which list the ships for which credit is split between two or more submarines or between submarines and aircraft. These “ofﬁcial” partial credits are frequently overlooked or ignored in other publications. Also, it was JANAC’s policy to assign credit to the agent responsible for ﬁnally sinking a ship, even though it may have been disabled or crippled by another agent only a few days earlier. An example might be a hulk torpedoed by a submarine after having been bombed and left adrift, or a ship badly damaged by a submarine and towed into port where it was sunk by aircraft before it could be repaired. In some other cases ships were so badly damaged that they became total constructive losses, but were never credited by JANAC as sunk. Alden’s evaluations give partial or full credit to submarines in a considerable number of such cases. Three attacks that resulted in known sinkings of U.S. ships also are understandably not mentioned in JANAC. On 26 March 1944 the Tullibee (SS-284) was sunk by a circular run of her own torpedo; one man survived to be taken prisoner and tell the tale after the war. The same fate befell the Tang (SS-306) on 24 October 1944; the commanding ofﬁcer Richard H. O’Kane and seven others were ultimately returned from a Japanese prisoner-of-war camp. On 23 January 1945 the Guardﬁsh (SS-217) ﬁred four torpedoes at what her commanding ofﬁcer thought was a Japanese submarine; two hit and sank the target, which turned out to be the USS Extractor (ARS-16). The 73 survivors were picked up by the Guardﬁsh, but six U.S. sailors were killed. 2. The British and Dutch ofﬁcial histories cited above agree with JANAC in most of their attributions. Unfortunately, neither publication cites its sources for identifying the Japanese ships claimed, so the few disagreements with JANAC cannot be explained. 3. Warships of the Imperial Japanese Navy

12 (WIJN) credits many sinkings to speciﬁc submarines. These appear to have been derived mostly from JANAC. Several erroneous attributions seem to be a misreading of U.S. submarine names or hull numbers, or errors in translation from Japanese to German to English. 4. The major published histories of World War II submarine operations have relied almost entirely on JANAC in claiming the ships sunk. (As noted, JANAC lists only total losses and does not count merchant ships or converted warships smaller than 500 gross tons.) Samuel Eliot Morison’s ﬁfteen-volume History of United States Naval Operations in World War II and the books by Roscoe, Holmes, and Blair (see Other Sources in this section) contain much information on U.S. but little on British and Dutch submarine operations. Blair’s is the only book written late enough to even mention code breaking and ULTRA, but actual ULTRA records had not yet been declassiﬁed and the author was denied access. These books were written primarily from a U.S. submarine point of view and none include complete listings of the ships sunk or damaged. The same comments apply to most of the individual submarine histories or memoirs published since the war.

Detailed Description of the 19 Data Elements Each attack record (a set of 19 data elements) contains information derived from combinations of the sources described. Because of the various ways in which data are presented in the sources, it is impracticable to detail each source’s contribution. For instance, the sources vary in their use of abbreviations for ship types and include many minor differences in dates, locations, and ship tonnages. Where signiﬁcant discrepancies exist in these data elements as well as in the identiﬁcation of the ships, extent of the damage, cause of the damage, or other data, we have included all relevant data sources. In such cases, the top line of data has been judged

13 the most reliable; conﬂicting information is shown in the appropriate data element(s) beneath the top line of data, or explained in the Comments. Minor differences are generally ignored. The listing is basically chronological, according to the order in which the attacks were made, insofar as this could be determined from the records. Ship casualties attributed to submarines, but for which no submarine attack could be found, have been inserted into the sequence according to the date given in the Japanese records. The ﬁrst ten data elements present information from U.S. and Allied sources, such as SORG for U.S. submarines and the British and Dutch ofﬁcial histories for their boats. In many cases, information taken directly from patrol reports has been used to provide greater detail or resolve questionable cases. 1. Submarine: hull number and name for U.S. submarines. British and Dutch submarines did not use hull numbers; their names are preceded by the designations HMS (British) or HNMS (Netherlands). Soviet submarines did not have hull numbers; their attacks are listed in “Soviet Submarine Attacks in the Paciﬁc, August 1945,” a separate section following the Chronological Listing of U.S. and Allied Submarine Attacks. 2. Ptl No.: the patrol number. U.S. patrols were numbered consecutively for each boat whether made in the Atlantic or Paciﬁc theater. For British and Dutch submarines, the numbers are for patrols in the Far East Theater only. The letter A after the patrol number indicates an attack by a U.S. submarine in the Atlantic theater. The letter L after the patrol number indicates that the submarine was lost on this patrol. 3. Commander: the name of the commanding ofﬁcer. 4. Mo/Yr: the month and year of the attack. 5. Dt/Hr: the date and, if known, the hour of the attack. The hour is generally as

A Detailed Explanation of the Data given in SORG. However, it appears that SORG took the times as shown in the patrol reports and rounded them off to the nearest hour without taking into consideration the zone time being used. U.S. subs usually indicated these zones as G (-7), H (-8), I (-9 or Tokyo time), K (-10), or L (-11), the number showing hours away from Greenwich Mean Time (GMT). In most cases the difference is not important, but it can be crucial when analyzing attacks on convoys by two or more submarines. Where necessary, patrol report times are adjusted to Japanese time and the exact hour and minute are indicated in the “Comments.” The absence of a date (indicated by —) means that no record of an attack associated with a reported case of sinking or damage could be found. 6. Position: the latitude and longitude are generally given for U.S. submarines. Many positions for British and Dutch submarines are given only as the general patrol area. 7. Target: an abbreviation of the ship type as reported by the U.S. or Allied source. Note that two or more targets (usually small craft) may be listed in a single entry where no further identiﬁcation is available. These are typically British submarine attacks on multiple junks of unknown name. If reported, the number of multiple targets attacked is shown in parentheses after the ship type. For example, Jk(3) is an attack on three junks. (See separate list and explanation of ship “Type” abbreviations below.) 8. Size Est.: estimated tonnage of the target. Note that the target’s size was almost always overestimated by the submarine commander. This was partly because of observational difﬁculties but also because U.S. recognition manuals often gave ﬁgures different from those used by Japanese sources. For instance, submarine ofﬁcers may have cited deadweight rather than gross tonnage when both ﬁgures were listed in the recognition manuals. (See the separate “Tonnage Measures” section below.) Early in the war submarine commanders tried to identify the ship being attacked, but were

A Detailed Explanation of the Data seldom accurate. In April 1944 Commander Submarines Paciﬁc told the skippers to stop trying to identify unknown ships and just use standard tonnages for the common types of merchant ships. 9. Attack Data: the type of the attack. Torpedo attacks are indicated by T followed by the number of hits out of the number of torpedoes ﬁred and a three-letter combination showing the nature of the attack. 1st letter: D day, N night, T twilight, M moonlight 2nd letter: U underwater, S surfaced 3rd letter: V visual, P periscope, R radar, S sonar Because of space limitations, if several salvos were ﬁred at a target in close succession, usually only the ﬁnal attack will be described but the total number of torpedoes ﬁred will be given. In some cases, salvos ﬁred at one ship resulted in hits on other ships in a group; in these instances the total number of torpedoes ﬁred appears only for the ﬁrst target listed, but the hits claimed are indicated for each ship separately. Where entries are incomplete, the missing information was not given in the sources used. Note that most submarine attacks early in the war were made with the boat submerged. Later, night surface attacks were found to be very effective, especially after radar became available. Because of a shortage of torpedoes at various times during the war, target priorities were set by higher commands and changed to suit circumstances. Many targets were missed at times when salvos were deliberately kept small. Torpedo problems existed throughout the war but were particularly serious during the ﬁrst two years; cases of dud hits, premature explosions, and erratic running torpedoes are well represented in the records. In the ﬁnal year of the war, some submarines were issued experimental homing torpedoes (called CUTY or DOGY) for use against attacking escorts. A single homing torpedo was usually ﬁred “blind” with the aid of

14 sonar as the submarine maneuvered to evade the enemy. As the war progressed and large targets became scarcer, surface gun attacks on small craft became more and more common. Although some of these targets were naval picket boats or converted naval types, many were obviously ﬁshing boats and not all were Japanese owned. Relatively few of these craft are listed in the Japanese records of losses; however, in most cases their sinking or damage was clearly observed by the submarine. Some were identiﬁed by boarding the craft, taking prisoners, or recovering material. The data tables include a few names found in the patrol reports and other records that were examined; others could probably be found by a more thorough search. Gun attacks are indicated by G followed by D, N, T, or M for the time of day, as above. 10. Claim: the damage claimed. Abbreviations used are as follows: S SJ P D DJ 0 U X

sunk sunk jointly by two or more subs (British usage) sunk, with partial credit to two or more subs (SORG usage) damaged damaged, joint credit no damage claimed unknown (used for submarines lost on patrol) not a valid attack

The next seven data elements present data on attacks from the post-war Japanese sources. Discrepancies between the various sources are explained in the “Comments.” 11. Reference Sources: the source(s) of information on the Japanese losses from the Japanese perspective. Multiple sources that agree appear on a single line. For example IJS on a single source line refers to three sources in agreement: IJN, JANAC, and Somerville. If sources disagree signiﬁcantly about one or more data items (ship name, date, tonnage, etc.) the sources are shown on separate lines, one below the other, or the discrepancy is explained in the

15 “Comments.” Abbreviations are used as follows: A I J M N PR S T U Ult W

Allan IJN JANAC Mühlthaler (see detailed list of his sources below) Netherlands source (described in “Comments”) Patrol report Somerville (see detailed list of his sources below) TROM (Tabular Record of Movements) USSL ULTRA WIJN

Other sources in speciﬁc cases are identiﬁed in the “Comments.” 12. Date: the date as given in the sources on Japanese losses. If the dates given by different sources vary by no more than one day from the date reported by the submarine, it is assumed that the variation is due to differences in reporting the time, and the range of dates is usually shown. Greater differences are indicated by separate entries and where possible are explained in the “Comments.” When a Japanese date is later than the attack date reported by the submarine, the sinking most likely resulted from the attack but occurred somewhat later. If the Japanese date is more than one day earlier than the submarine date, either the date was recorded incorrectly or attribution of the loss to the attack in question must be considered doubtful. 13. Location: the position as given by Japanese source(s). Generally preference is given to the source that indicated latitude and longitude; minor differences are ignored. Where sources used references to landmarks, these were checked to see if they were consistent with the geographical coordinates; if not, the attribution is indicated as questionable. Note that JANAC usually shows sinkings at the position reported by the submarine. Therefore, where

A Detailed Explanation of the Data JANAC locations are the only ones given, they are usually listed as simply “Sub position.” 14. Type: the Japanese classiﬁed ship types similarly but not identically to U.S. Navy usage. Warship classiﬁcations for the most part were the same in both navies but those for auxiliary types were quite different. Merchant ships taken over by the U.S. Navy usually were extensively “converted” or upgraded to naval standards for speciﬁc purposes (e.g., attack transports APA) and given new names. The Japanese requisitioned many more merchant ships for general purposes, made minimum alterations, and kept their “maru” names. The Imperial Japanese Navy and Army used separate classiﬁcation systems and employed requisitioned ships differently. As a result, U.S. type symbols can be only roughly assigned to their Japanese equivalents. The Japanese navy classiﬁed requisitioned ships in two main categories: those operated by navy crews are designated as X types (e.g., XPG for a merchant ship armed and used as a gunboat); and those manned by civilian crews are indicated as B types (e.g., B-AO oiler). Ships requisitioned by the army are usually shown under their original classiﬁcation in the shipping register (e.g., A-AK cargo ship), but the cargo and passenger types were used interchangeably to meet whatever need was immediately urgent. Most ships requisitioned as troopers were probably registered as cargo ships. Source WIJN simply lists all such ships as transports whether they were intended to carry cargo, passengers, or both. The type symbols shown in our attack listings should be considered approximations rather than rigid classiﬁcations and differences that appear in the various sources are of no importance. In addition, the army and navy operated chartered ships on a shared basis (A/C or B/C for army/civilian or navy/civilian.) In practice these ships left Japan with military cargos and returned under civilian control with cargo for the beneﬁt of the ship owner. Because of such changes in classiﬁcation, the same ship may be correctly shown with different type symbols at

A Detailed Explanation of the Data different times. A complete list of ship type abbreviations is given in a later section. Communication Ship (also called Shuttleboat in some sources) is the approximate translation of the Japanese type Kotsusen. To ease the transport problem caused by the heavy losses of ships, the Japanese required various local building yards in the Dutch East Indies to produce these seagoing wooden craft. They were about 115 feet long by 25 feet in beam with a gross registered tonnage of about 200 tons. Their speciﬁc characteristics are not known. They were apparently classiﬁed as civilian passenger vessels and not ofﬁcially operated by either the Imperial Japanese Army or Navy. All carried numbers with the sufﬁx “Go.” Although some are known with numbers in the 400s the actual number completed may not be that great. Little information exists about the origin of the Kotsusen program or the construction and speciﬁc employment of these ships. 15. Tons: the tonnage as given in Japanese source(s). Minor differences between sources are usually ignored; larger discrepancies are shown or noted in the “Comments.” Ships of merchant types are measured in gross registered tons, with preference to the ﬁgure given in Senji Nippon Senmeiroku. Warships are measured in displacement tons; usually the “standard” ﬁgure from WIJN or Watts is given. (IJN does not give [shown as NG] warship tonnages, and JANAC ﬁgures for warships are almost always smaller than those from postwar sources. Also see discussion in “Tonnage Measures” below.) 16. Vessel Name: the ship name as given in Japanese source(s), with the preferred identiﬁcation listed ﬁrst. The abbreviation M stands for Maru (meaning a ship’s name). Most merchant ships taken into naval service during the war retained their names. Also note there are many cases where the same name was used for two or more different ships, either with or without the addition of numerical designations. In Japanese usage, the number always appears ﬁrst, e.g. No. 1 Kaiyo Maru. To simplify alphabetization, we show the number after the name.

16 The word “Note” appears in place of the names of ships identiﬁed as missed, in ULTRA or other postwar records. In such cases, the names or other information will be given in the “Comments.” NG is shown when the source, usually an ULTRA report, conﬁrmed the attack but did not give the vessel’s name. Unident (for torpedo attacks) or Unk (for gun attacks) is shown when the attack is evaluated by Alden as successful. Ship names written in Japanese characters frequently pose a translation problem because the kanji can often be read in more than one way. Although the original ship owner knew what meaning was intended, this may not have been clear to later observers. Many cases of variant names occur in the source literature. These appear in this compendium with the preferred name listed ﬁrst and the alternate names enclosed in {braces}. Our principal source for the correct name is Senji Nippon Senmeiroku (Wartime Japanese Shipping Register) as translated by Erich Mühlthaler. This source derived the names from the ofﬁcial wartime registers (Nippon Senmeiroku) and gives the correct Romanization reading of the Japanese characters. Although the alternate names are all shown in {braces}, they are not necessarily “incorrect” in all cases. In addition to those that are variant readings of the kanji, others are: alternate spellings of the English name (e.g., Surabaya or Soerabaja); ships incorrectly attributed to submarines and evaluated as XE; or ships believed attributed by JANAC or other source to the wrong submarine, most commonly during “wolf pack” attacks. Mühlthaler explained the designation Go or I-Go was often applied to captured ships. If any part of a name appears in square brackets [ ] it is an unofﬁcial designation used by the Japanese navy, and it may appear in different sources. Mühlthaler elaborated that the Japanese designation “Go” is only a simple sufﬁx added to names without any deeper meaning. “xxxx Go” simply means that the name of the ship is “xxxx.” During the early stage of the war several captured vessels retained their names

17 and added a simple “Go” sufﬁx, while other captured vessels received the “Maru” sufﬁx from the beginning. Later in the war (about 1943) many “Go” were altered to “Maru.” Chartered ships like the Portuguese “Sado” (3033 grt) also received the “Go” sufﬁx, becoming the “Sado Go.” Also the Japanese navy made extensive use of “Go” with many variations. The reasons for the “renamings” were simple: before and during the war the Japanese navy requisitioned a large number of vessels with identical names. To differentiate these vessels the Navy applied a system of adding “Go,” “I Go,” “Ro Go,” “No. 1 Go,” etc. There were some “extreme” cases like ON 45297 Kaiyo Maru No. 2 which was “renamed” by IJN Kaiyo Maru No. 1 Go. It is very important to know that these were not ofﬁcial renamings, but only used internally by the Japanese navy. For present and future researchers we have printed these names in exactly the same style as shown in the Mühlthaler listings, that is with the square brackets shown. Regular Imperial Japanese Navy ship names do not include “Maru.” The following classes of warships had letter/number designations instead of names: Escort and patrol vessels, coast defense (WIJN Types C and D) Ch Submarine chasers Cha Auxiliary submarine chasers, including converted ﬁshing vessel and captured types Comm Communication ship (Kotsusen-type not listed in WIJN) HA Small and midget submarines I Large submarines Ma Coastal minelayers P Escort and patrol vessels (former old destroyers and captured ships) RO Medium submarines T Landing ships (WIJN type T 1 was a fast amphibious transport resembling the U.S. APD; the T 101 type resembled the U.S. LST) Tx1 Symbols used by IJN to designate unidentiﬁed losses CD

17. Damage: the extent of damage and agent (cause) as reported by Japanese source(s). Separate entries or “Comments” appear in all cases where “Sources” disagree as to either extent of damage or agent. Where only a single letter appears, it indicates the extent of damage, the agent being a submarine. Agents other than submarines are indicated by a second letter, but note the exceptions below. Abbreviations used are as follows: Extent of Damage S sunk T constructive total loss H heavy damage M medium damage L light damage or dud hit U unknown extent D damage, unspeciﬁed 0 none claimed Exceptions: S* is the JANAC notation for probably sunk. NG means Not Given. Agent A W M C U J

18. Comments: Although heavily condensed because of space limitations, most will be self-explanatory. The comment will generally start with the submarine commander’s patrol report (PR) with some details of the attack. This will be followed by information from ULTRA, SORG, and other sources. Sources are indicated by the same letters as used in the “Source” data except that speciﬁc Somerville and Mühlthaler sources will be identiﬁed with

A Detailed Explanation of the Data WS or M plus a number, such as WS1 or M1, respectively. WS or M alone refers respectively to information from Somerville’s or Mühlthaler’s records not otherwise speciﬁed. Their main speciﬁc sources are listed later. Square brackets [ ] indicate information not directly related to the speciﬁc attack, or in some cases the author’s own comments. Data believed to be erroneous are enclosed in braces { } within the “Comments.” See additional explanation in section 16, “Vessel Name.” 19. Alden Eval: The symbols represent Alden’s evaluation of the speciﬁc attack, based on his assessment of the evidence from all available sources and judgment as to their reliability. These evaluations are, of course, subjective, and will vary from case to case. Since all sources have been found to contain some errors, agreement is normally required on the part of at least two “usually reliable” sources to consider a case as conﬁrmed. Where sources disagree signiﬁcantly and cannot be reconciled, a lower rating is generally used. The symbols are deﬁned as follows: First symbol S Sunk T Total loss D Damaged L Light damage (also used for dud hits) H Hit on hulk or wreck 0 Not hit, no damage X Special case (see below) Second symbol 1 Conﬁrmed 2 Highly probable (used for gun attacks where name of target is given, but not conﬁrmed by a Japanese source) 3 Probable 4 Possible 5 Only remotely possible, unlikely Third or fourth symbol P Partial (shared or joint) credit A Indirect agent of damage L Lost submarine (no patrol report) D Doubtful identity of submarine

18 Q U E

Name of ship hit is questionable Unidentiﬁed ship (otherwise plausible case) Error (ship attacked by mistake)

Special cases XE Erroneous attribution by source XR Repeat attack evaluated after another hit In applying the above system, the criteria used for evaluating torpedo attacks differ from those used for gun attacks. Most of the evidence for torpedo attacks has come from postwar Japanese sources or wartime intelligence such as ULTRA intercepts, which were actually Japanese sources. Given the information now available identifying speciﬁc ships and convoys, and providing details about so many attacks, there is little reason to believe that many cases of sinking or appreciable damage remain unreported. A small number of ships are shown as “Unident” and evaluated as possibly sunk or damaged (S4U, D4U, L4U etc.) where there appeared to be some supporting evidence of a hit (even a dud hit, since these are known to have caused some damage). The cases evaluated as 03 (not hit), generally fall into one of the following categories: Japanese reports have speciﬁcally identiﬁed a ship as having been missed, or convoy reports have identiﬁed the only ships that were actually hit, or evidence in the patrol report was clearly weak. In the ﬁrst two cases “Note” is inserted in place of the ship’s name to indicate that information in the “Comments” positively supports the conclusion that no hit was made. Some cases evaluated as 03 may actually have been duds (in which case any damage would have been minimal) or in some rare cases multiple hits on a ship (in which case the damage is recorded under another attack). In the case of gun actions, the victims were mostly small craft such as ﬁshing or coastwise trading vessels. The submarine attacked on the surface at relatively close range, so had a reasonably good view of the results. However, until recently few such craft have been identi-

19 ﬁed in Japanese records and there is no reason to believe that many others will ever be positively identiﬁed. The patrol report claims have generally been accepted at face value as probably sunk (S3) or damaged (D3), although unidentiﬁed. Where evidence of sinking was stronger, such as vessels that were boarded or had prisoners taken, or there was some corroboration from a Japanese source, a claimed sinking was evaluated as conﬁrmed (S1) or highly probable (S2). On the other hand, boats left aﬂoat or not seen to sink, even if damaged or aﬁre, could well have been salvaged and repaired; if claimed as sunk, these are likely to be evaluated as possibly sunk (S4) or probably damaged (D3), which ratings are essentially equivalent.

Ship Type Abbreviations In identifying targets SORG uses a mixture of standard Navy classiﬁcation symbols plus nonstandard abbreviations for types that do not ﬁt exactly into the U.S. system. No distinction is made between naval auxiliaries and merchant ships of similar types, such as transports (AP) or tankers (AO). Each major source of Japanese data uses a different system for indicating ship types: JANAC does not use abbreviations but spells out the ship type; WIJN also spells out type designations, some of which are peculiar to the Japanese Navy and do not have exact U.S. equivalents; IJN uses a mixture of standard U.S. and nonstandard symbols for naval ships but spells out the common merchant types and also uses preﬁxes to indicate whether a ship was under army, navy, or civilian control. Since it would be meaningless to try to show all of the different type classiﬁcations in the data tables, the common U.S. abbreviation that appears to be most useful or meaningful is generally used. See the detailed explanation under 14, “Type.” Certain preﬁxes used with many of the ship classiﬁcation symbols listed below have the following meanings: X at the beginning of a ship type designa-

A Detailed Explanation of the Data tion signiﬁes a merchant ship “converted” or taken into naval service and manned by a naval crew. An exception to this rule exists in the case of merchant ships fully converted into warship types (such as aircraft carriers) rather than merely adapted to a naval role. In such cases the Japanese assigned new warship names in place of the original Maru names. Note that the symbol XPG, for example, means a merchant ship that was armed and used as a gunboat, not a “former gunboat” as stated in some sources. Larger ships used as armed merchant cruisers are designated XCL; these are not “former light cruisers.” The following other preﬁxes indicate the exact type of Japanese control: A B C A/C

Note 1: These were generally small coastal freighters. During the war the U.S. Navy issued a recognition manual, ONI 229, in which the designations Sugar Charlie (SC) and Sugar Dog (SD) were assigned to common types of these freighters, or “sea trucks.” In some cases this can lead to confusion between the Sugar Charlie and a submarine chaser. Note 2: The Japanese (WIJN) classiﬁcation of Escort and Patrol Vessel includes types similar to the U.S. destroyer escort and frigate, as well as converted old destroyers, trawlers, and captured ships of various types. SORG, IJN, and JANAC use the symbols DE, PF, and ODD for different ships in this group, but the usage is not consistent. In this book PF is used for all types listed in IJN as Escort and Patrol Vessels, and DE only for Matsu-class escort destroyers. The former names of patrol vessels converted from old destroyers, and of some other ships, are given in the comments. Note 3: Many varieties of small craft are listed under names for which there are no standard deﬁnitions. None of these type designations should be considered deﬁnitive in distinguishing one kind of small craft from another.

Tonnage Measures Because of the widely different methods of measuring ship tonnage, especially between warships and merchant types, tonnage totals for individual submarines are, at best, mere approximations resulting from the addition of “apples and oranges.” The “gross registered tonnage” of merchant ships is actually a measurement of volume, one ton being equal to 100 cubic feet of carrying capacity. Obviously, this ﬁgure could vary depending on when the ship was surveyed, because of structural alterations as well as the accuracy of the measurements. Bulk carriers such as tankers and ore carriers are frequently rated in “deadweight” tons, which represent the maximum weight of cargo that can be carried safely. Warships are measured in displacement tons, referring to the weight of the ship. Since ships cannot be weighed directly, displacement is calculated according to the volume of water displaced, using a standard value of 35 cubic feet of sea water per long ton (2,240 pounds). (Note that long tons are traditionally used rather than the common short tons of 2,000 pounds. Some countries, however, use metric tons, or “tonnes,” of 1,000 kilograms, or 2,204.6

22

A Detailed Explanation of the Data pounds.) Since the volume of water displaced will vary according to how deeply a ship is loaded, “standard” displacement was deﬁned in naval treaties as that of a ship fully manned and equipped for sea in wartime, but without fuel or reserve feed water. “Light” displacement refers to the ship and its machinery without crew, provisions, fuel, ammunition, and other expendable items. “Full load” displacement is the standard displacement plus fuel and feed water. The term “normal displacement” is also used in some references without being clearly deﬁned. In wartime, ships were almost always loaded beyond their nominal full load displacement, with extra crew members, stores, ammunition, guns, and other supplies. The actual displacement would, of course, change as stores and fuel were used during a cruise. The displacement of submarines is usually given either surfaced or submerged, with the surfaced ﬁgure measured in one of the ways described above. The difﬁculty of establishing a warship’s displacement is reﬂected in the variety of ﬁgures to be found in different reference publications. A rough idea of the relationships among different measures of ship tonnage can be obtained from the following ratios derived from average ﬁgures for World War II types compiled by Frederic C. Lane in Ships of Victory: Type

Since sources differ in detail as to the tonnage of most ships, and there is no way of determining whether one is more “correct” than another, most minor differences have been disregarded and readers are strongly discouraged from the practice of adding up tonnages as a means of ranking submarines or their commanding ofﬁcers.

ULTRA This brief and simpliﬁed description is based on information from the following books: Drea, Edward J. MacArthur’s ULTRA. Lawrence, KS: University Press of Kansas, 1992. Holmes, W. J. Double-Edged Secrets. Annapolis, MD: Naval Institute, 1979. Prados, John. Combined Fleet Decoded. New York: Random House, 1995. Stripp, Alan. Code Breaker in the Far East. New York: Oxford University Press, 1995 (paperback); ﬁrst published by Frank Cass, 1989. Winton, John. ULTRA in the Paciﬁc. Annapolis, MD: Naval Institute, 1993.

The term ULTRA was originally used to identify information derived from special intelligence, most often obtained by intercepting and decrypting Japanese coded radio messages. As used in this book, it may also include intelligence from trafﬁc analysis, captured documents, interrogation of prisoners, etc. The term “Magic” was also used, usually in connection with the decryption of Japanese diplomatic codes. Before a message could be decrypted, it ﬁrst had to be intercepted and copied by a radio operator, which was not as simple as it sounds. The classic Japanese language is written in ideographs derived from Chinese, called kanji. More than 1,850 of these were ofﬁcially recognized in the 1940s. These have been simpliﬁed into 51 syllabic characters called kana, which represent different sounds. Kana in Japanese are written in two systems: hiragana and katakana, the latter usually used to render foreign words. The kana can be recited like an alphabet (A Ka Sa Ta, etc.) or in a rhyming sequence commonly learned by children (I Ro Ha Ni, etc.). Kana when written in Roman letters are called romaji. To transmit messages by radio, the Japanese devised a version of Morse (dot-dash) code for their kana, but used the standard international code for numerals. Intercept operators had to be expert in both codes, using special typewriters to print out the 51 romaji kana. It

23 was easy to miss or misread characters because of weak or fading signals, interference, or atmospherics (static). Garbles are therefore fairly common in the ULTRA intercepts. Most Japanese naval messages were written in codes, which commonly used numerical groups to stand for standard words and phrases. These were usually then encrypted, or scrambled, by machines whose settings were usually changed daily. After a message was intercepted and copied, it had to be decrypted by teams of cryptanalysts. The coded text then had to be broken by reference to captured or painstakingly reconstructed copies of the Japanese code books. Decoded text had to be reduced to romaji kana to be read. Because knowledge of the Japanese encrypting systems was seldom perfect, and the codebooks were changed or replaced periodically, errors or gaps frequently appear in the messages. In the worst cases, decryption could be delayed by days or weeks before a changed code was broken. The ﬁnal step of translating Japanese messages into English required skilled linguists. Most kana can be read in more than one way, which presented special problems when trying to interpret things like the names of unknown ships or unfamiliar places. Because of the foregoing problems, ULTRA information was often sketchy, unclear, partially unintelligible, or even incorrect. Contrary to popular assumptions, the ULTRA codebreakers could not always provide complete, clear, and timely intelligence about Japanese plans or actions. Nevertheless, ULTRA information was of tremendous value to the Allies and proved to be a major factor in winning the war against Japan. The Japanese navy used many codes, some of which were never broken. The one used earliest in connection with submarine operations, JN-25, was a ﬁve-digit code dealing with warship movements. This code was apparently ﬁrst penetrated in 1940, but was changed in December and remained unreadable for several months. It was changed again several times during the war with similar delays in decryption. Relatively little intercepted information from

A Detailed Explanation of the Data this code was passed on to submarines because of fear that the Japanese might suspect that their messages were being read. On the few occasions when a submarine was informed of the routes being taken by Japanese carrier forces, it was seldom able to get into position for an attack on the fast-moving warships. Between November 1942 and January 1943 British and U.S. cryptanalysts succeeded in breaking the so-called Maru code, or JN-40. This code used groups of four kana to report the positions of merchant ships and standard phrases for describing encounters with submarines, damage received, etc. A similar Army Water Transportation Code was broken in March or April 1943. Information from these codes proved to be a bonanza for U.S. submarines in waylaying slow-moving convoys, although it was never as sureﬁre as it has since been reputed to be. It also provided evidence that targets were being missed although submarine commanders were sure they had been hit and sunk. This was circumstantial evidence that our torpedoes were not performing reliably. Unfortunately, little of this information was reported back to the submarine commanders, nor was it relayed effectively to the ofﬁcials responsible for producing the torpedoes. As a result, months were lost in getting the torpedo defects corrected. Before ULTRA information could be used to sink enemy ships, it had to be transmitted to our submarines. The inherent difﬁculties in communicating with boats thousands of miles away, that were usually submerged during daylight hours, are obvious. Submarines could receive very low frequency transmissions under water, but only quite close to the surface. Since one may not have been close enough to make contact with a reported target, it is not surprising that many intercepts could not be converted into sinkings. According to an analysis reported by Winton, from January through October 1943 ULTRA identiﬁed 809 potential targets, of which the great majority were never sighted by a submarine or were seen but could not be attacked. Only 120 ships were actually attacked, resulting in 33 sunk and 56 damaged.

A Detailed Explanation of the Data ULTRA was obviously of tremendous value in winning the war, but in day-to-day submarine operations it was not the panacea of popular imagination.

ULTRA says this was convoy MOTA-32 c/o 12 marus att @ 27-04N 120-26E, 7 ident listed below all continued operational. WS & M say that according to action reports from Manju, CD 31, & CD 144 convoy MOTA-32 (Moji-Takao) c/o Daikyo M, Tensho M, Samarang M, Aizan M, Shunsho M, Daishun M, Tamon M #16, and five unident marus, escorted by Shiokaze, Manju, CD31, CD 132, CD 144, Ch 19 & Ch 57. Hugging the coast and stopping overnight for shelter, it reached Namquan Harbor early 23 Jan. Already present was convoy TAMO-38, c/o Daikusu M, Bingo M, Toyokawa M, Rashin M, Shinno M, Tatsuwa M, and Nichiu M #7. The ships of MOTA-32 anchored in 5 columns closest to the bay entrance, Daikyo M dropping anchor around 0010 @ 27-02N 120-27E. At about 0515 it was hit by a torp in the starboard bow & another in #2 hold; the cargo of ammo blew up in a huge expl, killing 56 crew, 28 gunners, and 360 of 558 troops; also lost were 6 Daihatsu & 2 Shohatsu landing barges. Minor D, prob from falling debris, was incurred by Samarang M, Aizan M, Daishun M, Sunsho M, & Tamon M #16. The other 5 ships claimed hit by BARB have never been confirmed, although Fluckey in his book “Thunder Below” reports finding during a 1989 visit to the area that 3 sunken hulks were partially visible in the harbor for some years after the war. Except Daikyo M, all of the ships named here continued operational. On the remote chance that some of the 5 unident marus in MOTA-32 were sunk or damaged, the ones claimed by BARB’s PR are shown as possibly S or D. These should not be confused with the 5 mentioned above that received minor D from the expl of Daikyo M; because of the nature of the damage, they will not be listed separately.

APPENDIX: U.S. AND ALLIED SUBMARINE MINELAYING ACTIVITIES The main data table lists some ships that have been evaluated as victims of submarinelaid mines. The list cannot be considered deﬁnitive in this regard, however, because of the difﬁculty of assessing the true effectiveness of U.S. and Allied minelaying efforts. U.S. submarines were not equipped with special minelaying features but carried mines that had to be discharged from the torpedo tubes. Two mines could be carried in place of each spare torpedo, but usually mixed loads were carried. In such cases the submarines would preferably go directly to the location of the mineﬁeld; after getting rid of the mines (which were disliked by most U.S. submariners) the boat would proceed on a regular combat patrol. Most of the Allied submarines operating in the Far East laid mines in the way just described, but two British boats, the Porpoise and Rorqual, and the Dutch O-19, were ﬁtted with special external mine tracks or tubes which permitted them to carry much larger loads of mines. As noted, damage inﬂicted by mines cannot easily be attributed to speciﬁc submarines or other agents. Casualties may have occurred days or months after the ﬁeld was laid, although the Japanese would be expected to attempt to sweep a ﬁeld as soon as it was discovered. Also, any unswept mines would tend to lose their effectiveness as they aged. Aircraft mines were laid in many of the areas mined by U.S. submarines, but the locations of the air

drops were necessarily less precise than those of the submarine plants. If the Japanese records fail to include accurate positions for ship losses in mined areas (which is often the case), attribution of a particular casualty to a speciﬁc mineﬁeld is essentially guesswork. The Japanese laid many protective mine ﬁelds outside their ports and anchorages, and these resulted in many frightening encounters by U.S. and Allied submarines. Indeed several U.S. boats are presumed to have been lost to enemy mines, as were a number of Japanese vessels that strayed from the narrow swept channels. Finally, there was the menace of ﬂoating mines, usually ones that broke loose from their moorings and drifted far from their original sites. U.S. submarines encountered many of these while running on the surface in daylight and tried to sink them with deck gun or small arms ﬁre. It is quite possible that some otherwise inexplicable cases of ship sinkings or damage could have been caused by these wandering death traps. In 1946 the United States Strategic Bombing Survey, in The Offensive Minelaying Campaign Against Japan (see sources list for reference), made the ﬁrst ofﬁcial assessment of the U.S. mining effort and concluded that 27 ships were sunk and another 27 damaged by mines laid by U.S. submarines. Unfortunately, many Japanese ships claimed sunk or damage are unidentiﬁed in the published report or their 337

Appendix names do not appear in any of the major data sources used for this compilation. From a cursory investigation of Strategic Bombing Survey source documents in the National Archives, Alden concluded that the above ﬁgures were based on wartime intelligence reports that lack post-war corroboration or have since been demonstrated to be inaccurate. JANAC, published a year later than the Strategic Bombing Survey, attributes only ﬁve ships totaling 18,553 tons to U.S. submarine mines and does not identify the submarines involved. These are as follows: Unknown Maru* Fukken Maru Teikin Maru Nikko Maru Tamon M. #15

4,000 2,558 1,972 3,098 6,925

20 December 42 29 December 42 27 July 43 1 July 44 26 January 45

*This ship has since been identiﬁed by IJN as Mitsuki Maru, 3,893 tons.

JANAC also lists seven ships attributed to British mines that can be correlated to submarine-laid mineﬁelds. Six of these are claimed in the British Staff History (BSH) as follows: (estimated tonnage indicated by “e”): Special Sub Chaser No. 8 (Cha 8) Takekun Maru Kyokko Maru Hosan Maru #1 Nikkaku Maru Special Minelayer No. 1 (Ma 1)

One additional ship is attributed by JANAC to British mines but not claimed in BSH. It appears more likely to have been sunk by a mine laid by USS Guitarro (SS363): Yuno Maru

other missing or conﬂicting data. Several possible additions to the list of submarine mining victims are included in the main data table, but a deﬁnitive evaluation would require a more detailed study of both Japanese and U.S. records.

The above data are indicative of the weakness of ofﬁcial assessments made so soon after the war. Casualties attributed to mines by more recent Japanese data sources are often difﬁcult or impossible to correlate to speciﬁc submarine mineﬁelds because of indeﬁnite locations and

Tons: Ships reported by SBS with tons shown as NG were counted in the SBS summary totals as 1200 tons each and 300 tons each if damaged, but these ﬁgures do not appear in the detailed SBS tables. Comments: Mine characteristics: The detailed characteristics of British mines are not known to the author. HMS Porpoise and Rorqual laid mines from tracks in the superstructure; these were reportedly Mk XVI self-mooring mines of which 50 could be carried. HNMS O-19 had vertical mine tubes in the superstructure from which it laid T III T Vickers

339 moored-type mines. The T-class British subs laid M Mk II mines from torpedo tubes; these were presumably magnetic mines similar to the U.S. Mk 12.

Mines were laid by a/c in conjunction with 236 SILVERSIDES, which planted moored mines in Steffan Strait where a/c ground mines could not be laid. SBS credits SILVERSIDES with 1 2000T ship S (clearly Tsukushi on 4 Nov) and 3 ships damaged, 2 for 6000T and 1 u/i (probably the minesweeper on 4 Oct). None of the ships show tons that add to 6000, but the most likely are Mehaku on 4 Oct and Kakuya on 4 Nov, which are listed without tonnage but would typically be estimated at 3000T each. Although SBS claims Tsukushi as S, it lists other ships at the same latitude and longitude with no explanation as to why they were not claimed. In view of the uncertainties, I have listed all 12 of the ships reported in SBS as mined at Kavieng. Note that the Mk 10-1 mines laid by SILVERSIDES would have remained live indeﬁnitely unless swept.
