Preble was then about forty years of age, and his temper had not been sweetened by dyspepsia, of which he had been a victim for a long time. The Constitution was destined, under his command, to win for herself the famous name of "Old Ironsides" from the way in which her stout timbers resisted the tremendous cannonade of the forts and fleets at Tripoli. It was in this splendid cruise, too, that she gained her well-maintained reputation for being a lucky ship. In all her great battles she never lost her commanding officer, nor did any great slaughter ever take place on her decks, nor was she ever dismasted or seriously injured by war or weather, nor did she ever take the ground. Up to this time the Constellation had been the favorite frigate of the navy, but, beginning with Preble's great cruise, the Constitution became, once and for all, the darling ship, not only of the navy but of the nation. The only other heavy frigate in the squadron was the Philadelphia, thirty-eight guns, commanded by Captain William Bainbridge. Her tragic fate and the glorious manner in which it was avenged is one of the immortal incidents of the American navy.[7] The five small vessels were commanded by five young men, lieutenants commandant, according to the rank of the day, of which three--Hull, Decatur, and Stewart--reached the greatest distinction. Somers, the fourth, had a short but glorious career. The fifth, Captain Smith, was a brave and capable officer, but his name has been overshadowed by the four young captains, who made a truly extraordinary constellation of genius. Among the midshipmen in the squadron were two, Thomas MacDonough and James Lawrence, who achieved reputations equal to the three great captains.
