About Mochitsura Hashimoto
Mochitsura Hashimoto (橋本以行, Hashimoto Mochitsura; 14 October 1909 – 25 October 2000) was a Japanese officer and a submarine commander in the Imperial Japanese Navy during World War II. He was captain of the submarine I-58, which sank the American heavy cruiser USS Indianapolis in 1945 after its delivery of parts, gun and bullet, for the first atomic weapon used in wartime, Little Boy, prior to the attack on Hiroshima. Born in Kyoto and educated at the Imperial Japanese Naval Academy, Hashimoto volunteered for service in submarines and was aboard submarine I-24 during the attack on Pearl Harbor in 1941. Hashimoto commanded coastal patrol and training submarines off Japan for much of the war, and in 1944 took command of I-58, a submarine which was equipped to carry kaiten manned torpedoes. After a number of unsuccessful operations, under the command of Hashimoto I-58 sank Indianapolis on 30 July with two Type 95 torpedoes while on a midnight patrol. Hashimoto's submarine then returned to Japan, one of the few Japanese submarines to survive the war. Hashimoto was called to testify on behalf of the prosecution at the court-martial of Charles B. McVay III, the commanding officer of Indianapolis, a move which was controversial at the time. He was later part of an effort to exonerate McVay, which was eventually successful. Hashimoto, whose entire family died in the atomic bombing of Hiroshima, later became a Shinto priest. He died on October 25, 2000, five days before McVay's exoneration. Hashimoto spoke first with judge advocate Captain Thomas J. Leaving home for the first time, Hashimoto then attended the Imperial Japanese Naval Academy at Etajima for four years, studying Japanese history, engineering, and naval tactics, as well as judo and other military athletics.
