When volunteers were called for, the desperateness of the enterprise was fully explained; but the crew of the “Nautilus,” Somers’s own vessel stepped forward to a man. He selected four,--James Simms, Thomas Tompline, James Harris, and William Keith. From the “Constitution” he took William Harrison, Robert Clark, Hugh McCormick, Jacob Williams, Peter Penner, and Isaac Downes. Midshipman Henry Wadsworth (an uncle of the poet Longfellow) was chosen as second in command. Midshipman Joseph Israel, having vainly pleaded with Somers to be allowed to go, at the last moment smuggled himself aboard the “Intrepid,” and when discovered Somers had not the heart to send him back. Decatur and Stewart went aboard the “Nautilus” on the evening that the attempt had been planned. The three had been so closely united all their lives that Stewart and Decatur felt the seriousness of the moment. Even professionally the attempt seemed almost foolhardy, for several Tripolitan vessels had come to anchor just within the entrance, and to pass them even at night seemed an impossibility. Somers felt a premonition of his impending catastrophe, for just as they were about to return to their own vessels he took a ring from his finger and, breaking it into three pieces, gave each of them a part, retaining the third for himself. As soon as the night fell the “Intrepid” cast off her lines and went slowly up towards the harbor. The “Argus,” the “Vixen,” and the “Nautilus” followed her, while shortly afterwards Stewart on the “Siren” became so anxious that he followed, too. A haze that had come up when the sun went down hung heavily over the water, and soon the lines of the fire-ship became a mere gray blur against the dark coast-line beyond. The excitement upon the guard-ships now became intense, and both officers and men climbed the rigging and leaned out in the chains in the hope of being able to follow the movements of the ketch. Midshipman Ridgley, on the “Nautilus,” by the aid of a powerful night-glass aloft, managed to follow her until she got well within the harbor, and then she vanished. The suspense soon became almost unbearable, for not a shot had been fired and not a sound came from the direction in which she had gone. At about nine o’clock a half-dozen cannon-shots could be plainly heard, and even the knowledge that she had been discovered and was being fired on was a relief from the awful silence. At about ten o’clock Stewart was standing at the gangway of the “Siren,” with Lieutenant Carrol, when the latter, craning his neck out into the night, suddenly exclaimed,-- “Look! See the light!”
