Abe Kōsō

A native of what is now the town of Mikawa, Yamagata prefecture in northern Japan, Abe was a graduate of the 40th class of the Imperial Japanese Naval Academy in 1912.

He returned to naval artillery and torpedo school later that year, and did not graduate until late 1917, so he was unable to participate in combat operations in World War I.

He commanded the transport division for the Port Moresby Invasion Force in abortive Operation Mo during the Battle of the Coral Sea.

Nine US Marines who had been accidentally left behind during the raid were captured by Japanese forces, and moved as prisoners of war to Kwajalein, where they were held for about a month.

Abe was extradited to Guam,[citation needed] where a military tribunal convicted him on May 23, 1946, of "violation of the law and custom of war and the moral standards of civilized society.
