Capt. Charles McVay (USS Indianapolis) was the only US Navy captain in WW II to be courtmartialed for the loss of his ship.
They approached the commander of the Japanese sub that sank the ship (the war was over by then) and informed him of the court-martial. Due to his limited English, he misunderstood the Navy officers at his front door and began to explain that he was not supposed to be tried for his conduct during the war.
"We're sorry for the confusion," they explained. "It's not you who is on trial; it's our guy."
He later testified in court that the Indianapolis's course or speed meant nothing that night; because of the angle at which he had intercepted the warship, its fate was sealed the moment it was spotted. (The case against McVay was predicated on the charge that he hadn't navigated his ship properly; it came down to the amount of cloud cover versus his speed. There was absolutely no evidence of neglect or incompetence on his part and the weather was such that there was no obvious "correct" answer; he was well within his rights to exercise his judgement in choosing his course.)
