Clash of Empires in South China: The Allied Nations' Proxy War with Japan, 1935-1941 (Modern War Studies)

Japan's invasion of China in 1937 saw most major campaigns north of the Yangtze River, where Chinese industry was concentrated.

The southern theater proved a more difficult challenge for Japan because of its enormous size, diverse terrain, and poor infrastructure, but Generalissimo Chiang Kai-shek made a formidable stand that produced a veritable quagmire for a superior opponent-a stalemate much desired by the Allied nations.
