The leadership of this desperate enterprise was intrusted to Lieut. Richard Somers. Indeed, it is probable that the idea itself originated with him, for a commanding officer would be little likely to assign a subordinate a duty so hazardous. Moreover, there existed between Decatur and Somers a generous rivalry. Each strove to surpass the other; and since Decatur's exploit with the "Philadelphia," Somers had been seeking an opportunity to win equal distinction. It is generally believed, that, having conceived the idea of the "infernal," he suggested it to Preble, and claimed for himself the right of leadership. But ten men and one officer were to accompany Mr. Somers on his perilous trip. Yet volunteers were numerous, and only by the most inflexible decision could the importunate ones be kept back. The officer chosen was Lieut. Wadsworth of the "Constitution," and the men were chosen from that ship and from the "Nautilus." As the time for carrying out the desperate enterprise drew near, Preble pointed out to the young commander the great danger of the affair, and the responsibility that rested upon him. Particularly was he enjoined not to permit the powder in the ketch to fall into the hands of the Tripolitans, who at that time were short of ammunition. One day, while talking with Somers, Preble burned a port-fire, or slow-match, and, noting its time, asked Somers if he thought the boats could get out of reach of the shells in the few minutes it was burning. "I think we can, sir," was the quiet response. Something in the speaker's tone aroused Preble's interest, and he said,-- "Would you like the port-fire shorter still?" "I ask no port-fire at all," was the quiet reply. At last the day of the adventure was at hand. It was Sept. 4, the day following the last attack upon Tripoli. The sky was overcast and lowering, and gave promise of a dark night. Fully convinced that the time for action was at hand, Somers called together the handful of brave fellows who were to follow him, and briefly addressed them. He told them he wished no man to go with him who did not prefer being blown up to being captured. For his part, he would much prefer such a fate, and he wished his followers to agree with him. For answer the brave fellows gave three cheers, and crowded round him, each asking to be selected to apply the match. Somers then passed among the officers and crew of the "Nautilus," shaking hands, and bidding each farewell. There were few dry eyes in the ship that afternoon; for all loved their young commander, and all knew how desperate was the enterprise in which he had embarked.
