A. T. Mahan,
From Sail to Steam, Recollections of Naval Life
“ Midshipman Easy was strong on the necessity for the gunner mastering navigation, and had many instances in point where all the officers had been killed down to the gunner, who in such case would have been sadly handicapped by ignorance of navigation. I fancy the doubt seldom needed to be settled in service; the duties of midshipman and boatswain could rarely come into collision, if each minded his own business. By luck, just after writing these words, I for the first time in my life have found a plausible derivation for midshipman. ”
