Farragut lacked still three months of being thirteen years old when he passed through this tremendous ordeal of slaughter, the most prolonged and the bloodiest of his distinguished career. At his tender years and in his subordinate position there could be, of course, no demand upon the professional ability or the moral courage which grapples with responsibility, of which he gave such high proof in his later life. In the Essex fight his was but to do and dare, perhaps it may rather be said to do and bear; for no heavier strain can be laid upon the physical courage than is required by passive endurance of a deadly attack without the power of reply. In the celebrated charge of the Six Hundred at Balaklava the magnificent display of courage was at least aided by the opportunity allowed for vehement action; the extreme nervous tension excited by such deadly danger found an outlet in the mad impetus of the forward rush. Farragut has himself recorded a singular instance in the Essex fight, which illustrates the sufficiently well-known fact that in the excitement of approaching action the sense of danger is subdued, even in a man who has not the strong nerves that endure the passive expectation of death. "On one occasion Midshipman Isaacs came up to the captain and reported that a quarter-gunner named Roach had deserted his post. The only reply of the captain, addressed to me, was: 'Do your duty, sir!' I seized a pistol and went in pursuit of the fellow, but did not find him. It appeared subsequently that when the ship was reported to be on fire he had contrived to get into the only boat that could be kept afloat, and escaped, with six others, to the shore. The most remarkable part of this affair was that Roach had always been a leading man in the ship, and on the occasion previously mentioned, when the Phoebe seemed about to run into us in the harbor of Valparaiso and the boarders were called away, I distinctly remember this man standing in an exposed position on the cat-head, with sleeves rolled up and cutlass in hand, ready to board, his countenance expressing eagerness for the fight; which goes to prove that personal courage is a very peculiar virtue."
