Our muddy machine gun pits were transformed into Courage Clubs when bombs fell or Japanese warships pounded us from the sea. There was protocol to be observed, too, and it was natural that the poor fellow who might break into momentary terror should cause pained silence and embarrassed coughs. Everyone looked the other way, like millionaires confronted by the horrifying sight of a club member borrowing five dollars from the waiter.
