McVay III (July 30, 1898 -- November 6, 1968) was an American naval officer and the commanding officer of USS Indianapolis (CA-35) when it was lost in action in 1945, resulting in a massive loss of life. Of all captains in the history of the United States Navy, he is the only one to have been subjected to court-martial for losing a ship sunk by an act of war, despite the fact that he was on a top secret mission maintaining radio silence (the testimony of the Japanese commander who sank his ship also seemed to exonerate McVay). After years of mental health problems, he committed suicide. Following years of efforts by some survivors and others to clear his name, McVay was posthumously exonerated by the 106th United States Congress and President Bill Clinton on October 30, 2000.
