Reminds me of the story of the heavy cruiser USS Indianapolis sunk by a Japanese sub just after delivering A-bomb components to Tinian. The Navy fouled up and left the survivors in the water for days. Lots died from dehydration and shark attacks. The Navy needed a scapegoat and courtmartialed Captain McVay for "failing to zigzag". He finally committed suicide in 1968.
Yeah, relieving the Captain of the Roosevelt is total BS. I hear there is a petition to reinstate him, but doubt it will do any good.
