The Battle of Toungoo was one of the key battles in the Battle of Yunnan-Burma Road in the Burma Campaign of World War II and Second Sino-Japanese War. The failure of the Chinese to hold the city of Toungoo opened up the route for the Japanese to make their lunge to Lashio around the allied flank and into the Chinese rear.
