Battle of Northern and Eastern Henan
During the Second Sino-Japanese War the Japanese 1st Army under Lt. General Kiyoshi Katsuki drove the Chinese forces of General Cheng Chien's 1st War Area out of Northern and Eastern Honan until they were stopped by the disastrous 1938 Yellow River flood caused by the diversion of the Yellow River by the Chinese Army into the Chia-lu and Huai Rivers.
