As it is impossible to crowd into this sketch any considerable proportion of the adventures of Lieutenant Cushing, it seems best in illustration of the extraordinary quality of his bravery, to proceed at once to the narrative of his famous exploit in the destruction of the Confederate ironclad "Albemarle," which earned for him further promotion, the engrossed thanks of Congress, and congratulatory addresses from civic bodies in every part of the North.
This ironclad was built on the lines of the old "Merrimac," and like the latter had met the fire of our biggest guns without injury. In April, 1864, she had attacked and recaptured the town of Plymouth, situated near the head of Albemarle Sound, eight miles above the place where the Sound receives the waters of Roanoke River. She had beaten off our fleet at that place, sunk its principal boat, the "Southfield," and killed the commander, Flusser, of whom we have spoken in connection with an earlier conflict. In May, the "Albemarle" steamed out into the Sound and simultaneously engaged seven of our vessels, destroying the "Sassacuse," which had unsuccessfully tried to overwhelm her by ramming beneath the water-line. The Union ironclads were not light enough to cross the bar in front of the entrance to the Sound, and the officers of our fleet were much puzzled as to how to be rid of the annoyance.
Cushing finally submitted two plans to Admiral Lee, either of which had, he thought, a fair chance of success. One was for him to take a hundred men, with India-rubber boats ready for inflation, lead them through the dense thickets of the swamps adjoining Plymouth, and after inflating the boats turn the sailors into a boarding party that should overpower the "Albemarle's" crew. The other was the one adopted, although with many misgivings on the part of the admiral and of the assistant secretary of the navy, Mr. Fox. It looked like a modern repetition of the dramatic episode of David and Goliath, and they permitted themselves to hope that this youth of twenty-one might have as good fortune as his Biblical predecessor. In brief, it was arranged that William should proceed to New York and select two very small, low-pressure steamers, each carrying a howitzer and a torpedo. These he was secretly to convey along the coast to the Sound and there attack the big ironclad by night, in such manner as might appear best when the time was ripe for action.
The boats were secured. Each was about thirty feet long and carried a 12-pound howitzer, with a torpedo fastened to the end of a boom at the bow, the boom being fourteen feet long and supplied with a "goose-neck" hinge where it rested on the bow. One of the boats was lost before reaching Norfolk; but with the other Cushing went through the Chesapeake and Albemarle Canal to the Sound.
Starting at midnight, he found the Union fleet fifty miles up the Sound, expecting a visit from the enemy's ironclad. Here he explained the daring plan to his officers and men, and told them they were at liberty to go with him or not, as they might choose. All wished to go, and a few from other vessels also volunteered. On the night of October 27, the party steamed up the river.
What happened thereafter, is told so tersely by Cushing himself, in his formal report to Admiral Porter, that it seems fair to use his own words. Under date of October 30, he writes:
Sir: I have the honor to report that the rebel ironclad Albemarle is at the bottom of the Roanoke river.
On the night of the 27th, having prepared my steam launch, I proceeded up towards Plymouth with thirteen officers and men, partly volunteers from the squadron. The distance from the mouth of the river to the ram is about eight miles, the stream averaging in width some two hundred yards, and lined with the enemy's pickets.
A mile below the town was the wreck of the Southfield, surrounded by some schooners, and it was understood that a gun was mounted there to command the bend. I therefore took one of the Shamrock's cutters in tow, with orders to cast off and board at that point if we were hailed.
