Battle of Shanghai
13 Aug–26 Nov 1937 — Chiang throws his German-trained best — some 700,000 men — into three months of house-by-house fighting under naval guns, to prove China will fight and to pull the war onto the Yangtze axis. Casualties approach 250,000, including the army’s irreplaceable officer corps. The world watches from the Settlement’s rooftops.

The moment in context
“Space for time” meant surrendering territory in order to preserve enough forces and government to keep the war going. It began with an incident far too small for the war it started. During a night exercise a Japanese soldier went missing at roll call, and shots were exchanged in the dark at a stone bridge southwest of Peking (the ✕ at Marco Polo Bridge, 7 July 1937). Local commanders nearly settled it, as they had settled a dozen such incidents since 1931, but this time Tokyo reinforced. Chiang also refused to back down, because his currency was reformed, his German-trained divisions were ready enough, and his legitimacy had been mortgaged at Xi’an to resistance. Two charcoal arrows drove south from the Peking–Tianjin plain along the railways into Hebei and Shanxi, Japan’s war of lines, fast and mechanized and unstoppable in the open north. The other two arrows belong to the war Chiang chose. In August he attacked the Japanese garrison in Shanghai (the ✕ there), deliberately pulling the main war onto the Yangtze axis. There rivers, cities and mud favored the defender, and the world, watching from the International Settlement’s rooftops, could not ignore it. Three months of house-by-house fighting consumed his best divisions, with casualties approaching a quarter-million, including the irreplaceable junior officers Whampoa had spent a decade making.

- Why it happened — Tokyo’s escalation machine. Japan in 1937 had no plan to conquer China — it had a government too weak to refuse its field armies’ faits accomplis, a doctrine (“one decisive…

- What it changed — The government of the interior. The retreat to Chungking is a state amputating its own richest limb to survive: customs revenue, industry and the tax base of the Yangtze delta are…
Then ask the room: Was Chiang right to fight in 1937 — six years after Manchuria, arguably years before he was ready? The argued answer is on the chapter page →
