One of Robert Heinlein's characters once said that you were just as dead if killed in a police action versus an all-out war. Five sailors died on the aircraft carrier Hornet CV-8 during the battle of midway, but they died in an accident, and have been largely forgotten in the overall picture of a crucial battle. The report that I just finished doesn't even mention casualties, but in addition to the five killed, twenty were wounded.
