The following text illustrates one example of acting skipper: At Pearl Harbor, Burdick Brittin saw an ensign take command of his destroyer. On April 11, 1945, it was his own turn to take charge. Brittin: “With Ensign Stanley Caplan—who was officer of the deck at that time—as acting skipper, we went out of the harbor shooting with every weapon we had, like everybody else” http://www.thehistorynet.com/mh/blburdickbrittin/"
