The Battle of South Guangxi (traditional Chinese: 桂南會戰; simplified Chinese: 桂南会战; pinyin: Guìnán Huìzhàn) was one of the 22 major engagements between the National Revolutionary Army and Imperial Japanese Army during the Second Sino-Japanese War. In November 1939, the Japanese landed on the coast of Guangxi and captured Nanning. In this battle, the Japanese successfully cut off Chongqing from the ocean, effectively severing foreign aid to China's war efforts by the sea, rendering Indochina, the Burma Road and The Hump the only ways to send aid to China.
