The Xi’an Incident

12–26 Dec 1936 — Chiang Kai-shek is kidnapped by his own marshal and released only after agreeing to stop fighting the communists and face Japan. The United Front makes the coming war a national one.

China then opened a major battle at Shanghai, choosing to resist on the one ground where foreign observers would be compelled to watch.

- What it changed — The quagmire turns Japan’s eyes south. A million Japanese troops sink into China; the resources the war consumes exceed the resources it yields. The strategic conclusion Tokyo reaches by…
Then ask the room: Chiang Kai-shek traded a third of China for time. Was “trading space for time” a strategy or an excuse? The argued answer is on the chapter page →
