How to read this set: DOCUMENTED = the fact stands in a named source. DEBATED = the sources dispute it, and the dispute is printed. CLAIM = a claim carried as a claim, not as the page's finding. Every figure is labelled for what kind of figure it is — an official count, a demographic reconstruction, a tribunal's estimate, or a range across historians. Numbers the sources give differently are carried as ranges, flagged, never averaged. Items the record could not verify are carried as NOT VERIFIED, named, never filled.
1. China's war, 1937–1945 — the longest continuous great-power war
DOCUMENTED. China's war with Japan (full-scale from 7 July 1937; the war's opening aggression in 1931) was the Second World War's longest continuous conflict between major states and, after the USSR, its costliest in lives. It is told here from Chinese records and historians first, with Rana Mitter's Forgotten Ally — built on Chinese, Japanese and Western archives — as the principal English-language scholarly spine.
DOCUMENTED — the course. Japan seized Shanghai (after the three-month battle of August–November 1937, among the war's largest urban battles to that date), took Nanjing in December 1937, and drove on Wuhan (fallen October 1938) and the coast, while the Chinese government withdrew up the Yangtze to Chongqing, which became the war's most heavily bombed capital (the Chongqing bombings of 1938–43; Chinese records count the 1939–41 raids' dead in the thousands per major raid season — given here as documented episodes, not summed, because the accountings diverge). China did not collapse: Nationalist armies fought 22 major campaigns by the Nationalist official history's own classification (Taierzhuang, March–April 1938 — China's first major victory; the three defences of Changsha, 1939–42; and the disastrous Japanese Ichigo offensive of 1944), while Communist forces built base areas behind Japanese lines and fought the Hundred Regiments Offensive (August–December 1940). The human context includes deliberate catastrophe by China's own wartime government under invasion's pressure: the 1938 Yellow River flood, caused by Nationalist forces breaching the dikes at Huayuankou to slow the Japanese advance, killed Chinese civilians in numbers Chinese and Western scholarship range at roughly 400,000–900,000 (a range across historians; Diana Lary; Mitter) and displaced millions. A record that printed only Japanese atrocities against China would not be China's true history, and this class does not print it that way.
DOCUMENTED — the cost, as sourced ranges. The official accounting of the People's Republic of China: 20 million dead and 15 million wounded — 35 million casualties, 1937–45 (an official figure). Mitter and the Western scholarly literature commonly range China's dead at 14–20 million, military and civilian together, with some 80–100 million people displaced as refugees at some point in the war (an estimate of displacement, not a count). The Republic of China (Taiwan) official history gives Nationalist military casualties alone at c. 3.2 million (killed, wounded, missing), with Communist forces' records less complete — the incompleteness itself documented in Mitter. This class prints the range 14–20 million dead, sources named at both ends. What no serious source disputes: China's dead were predominantly civilians, killed by combat, massacre, bombing, flooding, famine (Henan, 1942–43: deaths ranged at roughly 1–3 million, within the war totals) and disease; and China tied down the large majority of the Imperial Japanese Army's ground strength for eight years. NOT VERIFIED — NV-3: the exact military/civilian split inside China's 14–20 million. The accountings' categories and windows (1931 vs 1937 starts; inclusion of flood and famine deaths) cannot be reconciled on present evidence, and no reconciled split is printed.
2. Nanjing, December 1937 – January 1938 — figures as tribunals and historians give them
DOCUMENTED. After Nanjing's fall on 13 December 1937, Japanese forces murdered Chinese prisoners and civilians and committed mass rape over a period of roughly six weeks. The toll is given exactly as the evidence's custodians give it, as a conflict across named authorities. The International Military Tribunal for the Far East (judgment, 1948) found "over 200,000" civilians and prisoners murdered in Nanjing and its vicinity in the first six weeks (a tribunal's estimate), citing burial-society records of over 155,000 buried bodies, excluding those burned, drowned or otherwise destroyed. The Nanjing War Crimes Tribunal (1947) found "more than 300,000" victims (a tribunal's estimate); 300,000 is the official Chinese figure, inscribed at the Nanjing Massacre Memorial Hall. Modern scholarly literature: Japanese historians' documented estimates range from c. 40,000 (the lowest serious scholarly figures, counting narrower categories and geographies) through Tokushi Kasahara's c. 100,000–200,000 to the tribunal figures; Bob Wakabayashi's synthesis of the Japanese records places December 1937's murdered, city and surrounding counties, in a band "far exceeding 100,000 but short of 200,000." Rape estimates in the tribunal record and the literature range from c. 20,000 upward.
DOCUMENTED. The span 40,000–300,000+ is printed as what it is — a spread produced by different counting frames (city walls versus six surrounding counties; six weeks versus longer; prisoners counted or not). The massacre's occurrence, its scale in the tens-to-hundreds of thousands, and its criminal character are established by Japanese soldiers' own diaries, foreign witnesses' records (the International Committee's documents; John Rabe's diary), burial records, and two tribunals. EXHIBIT, answered: denial or minimization below that documentary floor is carried only as an exhibit in how records are contested. The Japanese government's own position acknowledges killings of a large number of non-combatants, looting and violence after the city's fall while disputing the toll — a documented official position, printed as a position, against the tribunal record. NOT VERIFIED — NV-4: a precise Nanjing death toll beyond the tribunal/historian ranges. Counting frames differ and Japanese military records were destroyed or withheld; this class's position is the span, not a point figure.
3. Southeast Asia under occupation, 1941–1945
DOCUMENTED. Japan's southern offensive (December 1941 – May 1942) took Hong Kong (25 December 1941), Malaya and Singapore (15 February 1942 — some 80,000 British, Indian and Australian troops surrendered to a smaller Japanese force; the largest surrender in British military history, per the British official record and IWM), the Dutch East Indies (March 1942), Burma (to May 1942) and the Philippines (to May 1942). The occupations that followed are told from the occupied nations' historiographies first.
Indonesia. Japanese rule conscripted labour on a vast scale: rōmusha forced labourers numbered, in Indonesian and Dutch scholarly accounting (Shigeru Sato, 1994), in the millions recruited, with deaths among Javanese rōmusha alone estimated in a range of roughly 200,000–500,000 — wide because Japanese and Dutch records are both incomplete. Famine and requisitioning drove total Indonesian war deaths to a compiled range of 3–4 million (National WWII Museum compilation), an envelope the specialist literature treats as plausible but not countable to better precision. Politically, the occupation destroyed Dutch authority permanently: the Japanese-sponsored PETA army and the independence proclamation of 17 August 1945 — two days after Japan's surrender announcement — belong to Indonesia's own arc, not to a European epilogue.
Vietnam. Held under a Vichy French administration subordinated to Japanese garrisons until Japan seized direct control on 9 March 1945. The famine of 1944–45 in Tonkin and northern Annam killed, across the literature, from c. 600,000–700,000 (French colonial-era estimates, as cited by Geoffrey Gunn, 2011) through c. 1 million (Gregg Huff, Economic History Review, 2018 — about 8 per cent of the population) to 1–2 million (the Viet Minh's and the Democratic Republic of Vietnam's official figure; Ho Chi Minh's independence declaration of 2 September 1945 says "more than two million"). The full span is printed with its three authorities named, because each end is a record with an interest, with modern economic history between them. Causation is multi-factor in the scholarship — Japanese and French rice requisitioning and cash-crop conversion, transport collapse under Allied bombing, typhoon damage, and administrative failure to relieve (Huff; Gunn) — shown as a debate, while requisitioning under occupation is documented in both French and Japanese records.
Malaya and Singapore. Occupation brought the Sook Ching massacres of Chinese Malayans and Singaporeans (February–March 1942): Singapore Chinese community accounting and post-war scholarship range the dead at c. 25,000–50,000, against the much lower figure in Japanese military reporting — a perpetrator record read as a perpetrator record, and the range printed with both ends labelled.
Burma. Occupation, the Burma Independence Army's shifting allegiances, the Thai-Burma railway, and the 1944–45 campaigns fought across Burmese ground made Burma a battlefield nation twice over; Burmese national historiography treats 1942–45 as both an independence opening (Ba Maw's nominally independent state, 1943) and a devastation, and Aung San's Burma National Army's turn against Japan in March 1945 is a Burmese decision at the centre of the national record. NOT VERIFIED — NV-6: precise Indonesian (3–4 million) and Burmese war-death totals. The Indonesian envelope is a scholarly estimate of an order, not a count, resting on incomplete Japanese and Dutch records; Burma has no countable total in the consulted scholarship — the gap is stated, not filled.
Korea. Korea's war was colonization's war, not occupation's: annexed since 1910, Korea supplied conscripted labour (mines, factories, military construction across the empire), soldiers (from 1938 as "volunteers," from 1944 by conscription), and the women and girls forced into the Japanese military's sexual slavery system — its survivors' testimony, Japanese military documents, and the UN's Coomaraswamy Report (1996) constitute the evidence base; victim totals across the empire are ranged by specialist scholarship at tens of thousands to c. 200,000, a range whose width reflects destroyed records. Korean war deaths stand at a compiled 378,000–473,000 (National WWII Museum). Korean historiography's framing governs: 1945 is liberation (Gwangbok) and simultaneously the onset of division — both, in Korea's own telling, and both are printed.
Thailand alone in Southeast Asia avoided formal occupation or colonization, by alliance with Japan (December 1941) purchased at the price of hosting Japanese transit and declaring war on Britain and the United States (January 1942 — a declaration the Thai ambassador in Washington refused to deliver and the United States therefore never treated as operative, a documented diplomatic singularity). The Free Thai movement's parallel resistance is part of Thailand's record, told from Thai historiography.
4. The Pacific war: Pearl Harbor to the island campaigns
DOCUMENTED. Japan attacked the United States Pacific Fleet at Pearl Harbor on 7 December 1941 (2,403 Americans killed — the U.S. official count; Japanese losses 64) while invading Malaya, Hong Kong and the Philippines and bombing Singapore, Guam and Wake. The United States declared war on 8 December; Germany and Italy declared war on the United States on 11 December. Japan's carrier force also raided Darwin, Australia (19 February 1942) — the first of dozens of air raids on northern Australia (Australian War Memorial), a fact that anchors Australia's war in its own north, not only in its expeditionary forces' service abroad.
DOCUMENTED. The naval-air turning points are operational facts: Coral Sea (4–8 May 1942), the first carrier battle, which turned back the Port Moresby seaborne invasion; Midway (4–7 June 1942), where U.S. carrier aircraft sank four Japanese fleet carriers (Parshall & Tully, Shattered Sword, 2005, revising the Japanese-side record); and Guadalcanal (August 1942 – February 1943), the first Allied land offensive, fought also on Papua New Guinea's Kokoda Track by Australian forces. From 1943 the Allied advance ran on two axes — MacArthur's Southwest Pacific advance through New Guinea to the Philippines, and Nimitz's Central Pacific island campaign: Tarawa (November 1943), the Marshalls, Saipan (June–July 1944 — whose fall brought down the Tojo government and put Japan's home islands in B-29 range), Iwo Jima (19 February – 26 March 1945), and Okinawa (1 April – 22 June 1945).
DOCUMENTED. The Battle of Manila (February–March 1945) killed some 100,000 Filipino civilians by the Philippine and American scholarly accounting commonly cited — a range of c. 100,000–120,000 across the literature. The Bataan Death March (April 1942) killed Filipino and American prisoners in numbers ranged at c. 5,000–18,000 across the accounting traditions, the Filipino dead the larger and less completely recorded share. The Philippines' total stands at a compiled 500,000–1,000,000 (National WWII Museum) — a range whose width measures the occupation's uncounted rural dead. Okinawa's dead state the endgame's scale: Japanese military dead c. 77,000+ by Japanese official accounting (plus Okinawan conscripts and militia); Okinawan civilian dead ranged by Okinawa Prefecture's own accounting and the Cornerstone of Peace memorial at roughly 94,000–150,000 — between a quarter and a third of the prefecture's population, including in mass suicides ordered or induced by the Japanese military, documented in Okinawan testimony and Japanese historiography (the textbook controversies over that documentation are a live, shown dispute in Japan — DEBATED); American dead c. 12,500 (U.S. official). Okinawa's ranges are printed from Okinawa's own memorial record first, as this programme's law requires.
5. Prisoners, forced labour, and the railway
DOCUMENTED. The Thai-Burma Railway (1942–43) killed, by the Commonwealth War Graves and Dutch and Australian official accountings, roughly 12,000–13,000 Allied POWs and — the figure that reverses the usual telling — at least 70,000 and possibly 90,000 or more Asian labourers (rōmusha from Malaya, Burma, Java and elsewhere), whose names were mostly never recorded: the Asian dead of the railway outnumber the POW dead by at least five to one in every accounting, and the asymmetry of the record (POWs named, rōmusha largely uncounted) is stated here as evidence, not corrected by invention.
DOCUMENTED. Unit 731's biological-warfare experimentation programme at Pingfang, Harbin — human experimentation and field attacks with plague and other agents — is documented through the Khabarovsk trial record (1949), Japanese veterans' testimony, and Chinese investigation. NOT VERIFIED — NV-10: a victim total for Unit 731's programme. The evidence is real but partial; field-attack claims cannot be reconciled into a single verified total. Pingfang experiment victims alone are ranged at c. 10,000–14,000 across sources, and no total is printed.
6. The road to the home islands, and the end in Asia
DOCUMENTED. In Burma, Slim's Fourteenth Army — British, Indian, African and Gurkha formations — destroyed the Japanese armies in 1944–45 and re-entered Rangoon on 3 May 1945. In the Philippines, the Leyte landings of 20 October 1944 opened the campaign that destroyed the Imperial Japanese Navy as an offensive force at Leyte Gulf (23–26 October 1944), the largest naval battle in the documented record by most measures, in which Japan first used organized kamikaze attacks. In the air over Japan, conventional fire-bombing had by mid-1945 destroyed the greater part of the built-up area of dozens of Japanese cities (U.S. Strategic Bombing Survey figures) — including the Tokyo fire raid of 9–10 March 1945, its dead ranged at c. 80,000–100,000+ in Japanese and American accountings, the deadliest single air raid of the war on most accountings; in the sea lanes, the U.S. submarine campaign had destroyed over 8 million tons of Japanese merchant shipping (Japanese post-war accounting), starving Japan's war economy.
DOCUMENTED — the atomic decisions, in brief. Hiroshima was bombed on 6 August 1945 and Nagasaki on 9 August 1945 — the first and second, and still the only, wartime uses of atomic weapons (U.S. Army official records; the cities' memorial records). The dead are taught as estimates, with the two authorities' methodological conflict shown in full, in the third class of this set: The World the War Drew In — and Its Cost. The one documented operational fact that frames the whole debate stands here: Japan did not surrender after Hiroshima; its government debated through 7–9 August.
DOCUMENTED — the end in Asia, dates precise. The USSR declared war on Japan on 8 August 1945 and invaded Manchuria, Korea, Sakhalin and the Kurils from 9 August — an operation of some 1.5 million Soviet troops that destroyed the Kwantung Army in eleven days (Soviet official and Japanese post-war accountings converge on the campaign's one-sidedness). Emperor Hirohito's surrender broadcast was recorded on 14 August and aired on 15 August 1945 (Japan time — 14 August in North America, both dates printed with their reason); the formal Instrument of Surrender was signed aboard the USS Missouri in Tokyo Bay on 2 September 1945 — VJ Day. In the China theatre, the formal Japanese surrender to China was taken at Nanjing on 9 September 1945 — China's war ending where its capital's catastrophe began, a symmetry Chinese commemoration preserves and this class records as commemoration's fact. The historians' debate over the surrender — the traditional account (the bombs ended the war and spared an invasion's toll) against the revisionist account (timing and the second bomb addressed to Moscow) — is carried as a DEBATED question in the study questions below, on this documented sequence.
Study questions — from Sets W-3 and W-4
Argue from evidence, compare authorities, evaluate claims. Where a question names a figure, use it exactly as stated above, named source and kind of figure included.
- (W-3.1) China's dead are printed as 14–20 million, with the PRC's official figure at the range's top, Mitter and the Western scholarly literature spanning the range, and the military/civilian split entered as NOT VERIFIED (NV-3). A classmate objects: "A range that wide is just admitting we know nothing." Answer the objection with evidence: state three things the range does establish with certainty (China's predominant civilian dead; the war's eight-year duration tying down the majority of Japan's ground strength; famine, flooding and bombing inside the toll), and explain why printing a single midpoint figure would be a less truthful act than printing the range.
- (W-3.2) Nanjing, December 1937: the International Military Tribunal for the Far East found "over 200,000" murdered in the first six weeks; the Nanjing War Crimes Tribunal found "more than 300,000"; modern scholarly estimates that count narrower frames run from c. 40,000 upward, with Wakabayashi's synthesis at 100,000–200,000. Show, from the tribunals' own stated counting frames (geography, window, whether destroyed bodies and prisoners are included), how several of these figures can be honest measurements of different things — and then state, with the evidence assembled above, what no counting frame can honestly bring into doubt, and how this class handles claims that try (the EXHIBIT discipline).
- (W-4.3) Japan did not surrender after Hiroshima: the government debated through 7–9 August; the USSR declared war on 8 August and invaded Manchuria on 9 August; Nagasaki was bombed the same morning; the Emperor's broadcast came on 15 August (Japan time), the formal surrender on 2 September. Using this sequence as your evidence, evaluate the two historiographical positions named above — stating what each explains well, what each handles badly, and what the documented sequence itself forbids any honest account to claim.
