Having chased Chiang Kai-Shek back to Chongqing, the Japanese Empire is still unable to get him to surrender. So, on to Chongqing it is, but events in Europe: The Molotov-Ribbentrop Pact, Nazi Germany’s invasion of Poland and then the war in the West will stymie one Japanese government after another. Which leaves Japan to head towards SE Asia and in conflict with the United States, setting up the attack on Pearl Harbor.
It’s the beginning of the end for the Allied defense of Burma. While Gen. Slim’s men are pushed back, their Chinese Allies in the Shan States of attacked and scattered. Their only hope of survival is to head back home. Another seemingly Japanese victory.
