The quiz

The Beiyang Army was loyal to its paymaster, not to the republic. Strongman rule is a substitute for institutions, not a form of them — and the bill arrives with the strongman’s obituary. Every warlord of the next decade was a piece of his estate.

China had joined the Allies and sent 140,000 laborers to the Western Front — and learned at Paris that Shandong had been secretly promised to Japan. The betrayal discredited the West as model and the treaty system as remedy in one afternoon, and both later party-states were staffed by the generation it radicalized.

Warlord soldiers were assets, not believers — fifteen years of army-as-business meant no one would die for his employer. The NRA marched on rails of propaganda as much as artillery and more than doubled by absorbing defectors. Tingsi Bridge showed what the new kind of army could do; the defection rate showed what the old kind was worth.

German-advised blockhouse warfare refused the mobile battle the Red Army had used to eat the first four campaigns battalion by battalion. Against concrete and blockade, the soviet’s conventional counter-defense at Guangchang failed — and breakout became the only arithmetic left. The Long March begins as a consequence of engineering.

Zhang Xueliang wanted his homeland back and would not spend his army on Communists instead of Japan. Stalin urged Chiang’s release (a living Chiang was the only leader who could pin Japanese armies away from Soviet borders); Zhou Enlai negotiated it. The CCP survived 1936 because of a mutiny it did not start.

In the open north, Japan’s mechanized war of lines was unstoppable; on the Yangtze, rivers and cities slowed it to a crawl — at the price of a quarter-million casualties and the Whampoa officer corps. “Trade space for time” was announced doctrine: China’s strategy was to still be in the war when the world war arrived. It worked, at Chinese expense.

Half a million men cut the corridor you see on the map — and changed nothing about Japan’s defeat, arriving from the Pacific. What Ichigo decided was Chinese: Washington stopped planning around Chiang’s army, and the public absorbed that after seven years the state could still lose a province in a season. The campaign’s true victor sat in Yan’an, untouched by it.

Johnson’s Peasant Nationalism and Communist Power (1962) put the occupation at the center. Selden and later scholars answered that the “Yenan Way” — land policy, taxation, institutions — built support the invasion alone cannot explain; Chen Yung-fa documented the coercion braided through both. The debate is the question “why did Mao win?” in scholarly form — and a model for weighing structural against political explanations.
