To continue with the story, Captain McVay was court martialed for failing to zig-zag his ship which was supposed to make them a more difficult target for torpedoes, although most sub experts said it was a waste of time.
The U.S. Navy even brought in Commander Mochitsura Hashimoto, the captain of the I 58 to testify against him.
Captain McVay was found guilty. The verdict was later set aside and he was returned to duty. He retired from the Navy in 1949.
The Indianapolis claimed its last victim on Novermber 6, 1968 when Captain McVay took his own life.
Note: The mission of the Indianapolis was to take the first atomic bomb to the Enola Gay on Guam. They succeeded and were sank on their way back to their base at Tolosa, Leyte, Phillippines.
