After this encounter, the three United States vessels proceeded to Malta. Here Commodore Morris found orders for his recall, and he returned to the United States in the "Adams." In his place Commodore Preble had been chosen to command the naval forces; and that officer, with the "Constitution," forty-four, arrived in the Mediterranean in September, 1802. Following him at brief intervals came the other vessels of his squadron,--the "Vixen" twelve, "Siren" sixteen, and "Argus" sixteen; the "Philadelphia" thirty-eight, and the "Nautilus" twelve, having reached the Mediterranean before the commodore. Three of these vessels were commanded by young officers, destined to win enduring fame in the ensuing war,--Stephen Decatur, William Bainbridge, and Richard Somers. Before the last vessel of this fleet reached the Mediterranean, a disaster had befallen one of the foremost vessels, which cost the United States a good man-of-war, and forced a ship's crew of Yankee seamen to pass two years of their lives in the cells of a Tripolitan fortress. This vessel was the "Philadelphia," Capt. Bainbridge. She had reached the Mediterranean in the latter part of August, and signalled her arrival by overhauling and capturing the cruiser "Meshboha," belonging to the emperor of Morocco. With the cruiser was a small brig, which proved to be an American merchantman; and in her hold were found the captain and seven men, tied hand and foot. Morocco was then ostensibly on friendly terms with the United States, and Bainbridge demanded of the captain of the cruiser by what right he had captured an American vessel. To this the Moor returned, that he had done so, anticipating a war which had not yet been declared. "Then, sir," said Bainbridge sternly, "I must consider you as a pirate, and shall treat you as such. I am going on deck for fifteen minutes. If, when I return, you can show me no authority for your depredations upon American commerce, I shall hang you at the yard-arm." So saying, Bainbridge left the cabin. In fifteen minutes he returned, and, throwing the cabin doors open, stepped in with a file of marines at his heels. In his hand he held his watch, and he cast upon the Moor a look of stern inquiry. Not a word was said, but the prisoner understood the dread import of that glance. Nervously he began to unbutton the voluminous waistcoats which encircled his body, and from an inner pocket of the fifth drew forth a folded paper. It was a commission directing him to make prizes of all American craft that might come in his path. No more complete evidence of the treachery of Morocco could be desired. Bainbridge sent the paper to Commodore Preble, and, after stopping at Gibraltar a day or two, proceeded to his assigned position off the harbor of Tripoli.
