She remained in port because of continued mining conducted by U.S. Army Air Forces, and departed on 16 July on another war patrol. She heard explosions at 15:21 and 15:31 but her crew was unable to determine if the kaitens had struck their targets. Every minute seemed an age. The list of most successful U-boat commanders contains the top-scoring German U-boat commanders in the two World Wars based on their total tonnage sunk.. He was 93. After an hour at a deep dive to reload, she surfaced and did not spot Indianapolis. "[57] Hashimoto later authored a book Sunk: The Story of the Japanese Submarine Fleet, 1941–1945 in which he detailed Japanese submarine operations in the war, including an account of the sinking of Indianapolis. Christened three months after Pearl Harbor, Wahoo was commanded by the astonishing Dudley W.

[58][59][60], In December 1990, Hashimoto met with some of the survivors of the Indianapolis at Pearl Harbor, where he stated through a translator: "I came here to pray with you for your shipmates whose deaths I caused," to which survivor Giles McCoy simply responded: "I forgive you."[57]. Commanded by Dudley “Mush” Morton, Wahoo was one of the most successful American submarines of World War II. Regarding McVay's conviction, Hashimoto wrote: Our peoples have forgiven each other for that terrible war and its consequences.

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. The American submarine fleet was largely the product the decision by the Navy General Board in 1911 to consider the development of a "fleet submarine", capable of sustained 21 knot speed and good seakeeping so that it could operate with the battle fleet. Hashimoto ordered the submarine to make for an area where he believed shipping lanes between Guam, Leyte, Peleliu and Okinawa intersected. [53] Even after his departure his testimony remained controversial, and the Chicago Sun criticized his trip, which it estimated to have cost $1,820 (equivalent to $25,800 in 2019).

The kaitens tentatively claimed a tanker sunk, though it was unable to verify if the ship had actually been struck. I-24 remained at a rendezvous point to wait for the midget sub, which never came. [42] When Hashimoto came home from the war, he learned that his entire family had been killed in the atomic bombing of Hiroshima on 7 August. [46] Hashimoto's 50 minutes of testimony focused on whether or not Indianapolis was "zigzagging" and he noted the ship did not deviate from its course. On completion in 1942 the vessel was renamed from I-76 to I-176 and was sent initially to Truk in September 1942.

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. [22] I-58 was commissioned on 13 September 1944 and Hashimoto commanded her during her shakedown cruises, commanding his men on repeated drills without shore leave. Sailing 26 September with Shad (SS-235), she rendezvoused with Cero (SS-225) at Midway Island to form the first of the Submarine Force's highly successful wolfpacks.
