It was this last type of boat which Lieutenant W. B. Cushing brought down to Albemarle Sound to use against the great Confederate ram Albemarle. The ram had been built for the purpose of destroying the Union blockading forces. Steaming down river, she had twice attacked the Federal gunboats, and in each case had sunk or disabled one or more of them, with little injury to herself. She had retired up the river again to lie at her wharf and refit. The gunboats had suffered so severely as to make it a certainty that when she came out again, thoroughly fitted to renew the attack, the wooden vessels would be destroyed; and while she was in existence, the Union vessels could not reduce the forts and coast towns. Just at this time Cushing came down from the North with his swift little torpedo-boat, an open launch, with a spar-rigged out in front, the torpedo being placed at the end. The crew of the launch consisted of fifteen men, Cushing being in command. He not only guided his craft, but himself handled the torpedo by means of two small ropes, one of which put it in place, while the other exploded it. The action of the torpedo was complicated, and it could not have been operated in a time of tremendous excitement save by a man of the utmost nerve and self-command; but Cushing had both. He possessed precisely that combination of reckless courage, presence of mind, and high mental capacity necessary to the man who leads a forlorn hope under peculiarly difficult circumstances.
