インパール作戦
In 1944, the Japanese launched a major invasion of India. During the long Battle of Imphal, 17th Division first successfully fought its way out of encirclement at Tiddim, and then disputed the vital Bishenpur sector south of Imphal (with 32nd Indian Infantry Brigade temporarily under command). In July, the Japanese were broken by heavy casualties and starvation, and retreated. Some units of 17th Division had suffered nearly 100% casualties.
