Touching at Tangier for information, and learning that the Algerine vessels had been heard from but a short time before, the commodore proceeded up the Mediterranean, and off Cape de Gatt he fell in with the enemy's flagship, the "Mezourah," commanded by the Rais Hammida, the bravest and most skilful officer in the Algerine navy. The "Mezourah" was a beautiful frigate, originally a Portuguese, and sailed uncommonly fast. Hammida at first supposed that the ships were English, as no one could dream that an American squadron of such force was in that neighborhood; but one of the vessels having hoisted American colors by mistake, he was undeceived, and speedily took to his heels. The "Constellation," being nearest to him, opened fire; but Decatur could not resist the temptation, and signalling to her to sheer off, he dashed up in the "Guerrière" until he was alongside the enemy. Then he gave her one of those thundering broadsides which had so many times carried dismay and destruction to English frigates. The Rais was killed, his body cut in two by a shot; his ship was shattered, and his people fell on all sides about the decks. The survivors were demoralized, and hardly returned the fire. A second broadside was discharged, and the "Mezourah" turned to flee; but the little "Epervier," herself a trophy of the last war, was in her path, and the Algerine surrendered.

Two days later the squadron fell in with another of the enemy's ships, the brig "Estedio." She took to flight, and being near the Spanish coast, ran into shallow water, where the large ships could not follow her. The brigs and schooners were sent in after her, and attacking her hotly, she was run ashore, and presently surrendered. She was floated off without much delay, and was sent with the other prize to Carthagena.

Further concealment was useless; and the commodore, having now nearly five hundred Algerine prisoners, decided to proceed to Algiers, and on the 28th of June he entered the bay. The Dey was amazed at the sight of the squadron, and, fearful for the safety of his cruisers, all of which were now out, he sent the captain of the port with the Swedish consul-general to ascertain the purposes of the American commodore. Decatur received them with due ceremony, dressed in his full uniform and surrounded by his officers. After exchanging courtesies, he asked the captain of the port what had become of the Algerine squadron.

"By this time," answered the wily Turk, "it is safe in some neutral port."

"Not the whole of it," rejoined the commodore; and then he told the story of Hammida's death, and the capture of the "Mezourah" and the "Estedio."

This did not satisfy the official, who shook his head and smiled, as much as to say, "That is all very well, but you don't expect me to believe your story."

"Wait a moment," said Decatur; and he sent for the "Mezourah's" lieutenant, who, coming on deck enfeebled by his wounds, briefly recited the circumstances of the two captures.

The captain of the port was no longer incredulous, but began to realize the seriousness of the situation. Alarmed and anxious, he asked the commodore what terms he offered. Decatur's reply was brief: "No tribute; no ransom; liberation of all American captives; immunity of all American ships and crews in future."

Hearing this answer, the captain of the port hesitated and proposed a truce, during which the commissioners should negotiate on shore. But the commodore declared that all the discussion should be on board his flagship, and that he would not cease from hostilities a moment until the treaty had been signed. With this answer the captain of the port returned to his master.

The Dey's wrath was great when he learned the news, but his alarm was even greater. On the next day the captain of the port returned, and the commodore gave him a copy of the proposed treaty. Still he demurred, seeking to gain time. He asked again for a truce, and again it was refused. He begged for three hours to consider the terms, but the commodore answered, "Not a minute;" and he added to the messenger, "If your squadron or one of your ships appears in sight off the port before the treaty is signed, I will capture it." All that he would promise was that if the boat, returning with the treaty signed, should hoist a white flag, hostilities should then cease. The captain of the port then took the treaty and pulled for the landing five miles away.
