Commodore Preble shook his head. It could not be done that way. He would only lose his own vessel and his men. But there was a way it might be done. The Moors might be taken by surprise and their prize burned in their sight. It was a desperate enterprise. Every man who took part in it would be in great danger of death. But that danger did not give much trouble to bold young Decatur, who was as ready to fight as he was to eat. What was the commodore's plan, do you ask? Well, it was this. Some time earlier the _Enterprise_ had captured the _Mastico_, a vessel from Tripoli. Preble gave this craft the new name of the _Intrepid_ and proposed to send it into the harbor. The Moors did not know of its capture and would not suspect it, and thus it might get up close to the _Philadelphia_. Decatur was made commander and called for volunteers. Every man and boy on the _Enterprise_ wanted to go; and he picked out over seventy of them. As he was about to leave the deck, a boy came up and asked if he couldn't go, too. "Why do you want to go, Jack?" "Well, Captain, you see, I'd kind o' like to see the country." This was such a queer reason that Decatur laughed and told him he might go. One dark night, on February 3, 1804, the _Intrepid_ left the rest of the fleet and set sail for the harbor of Tripoli. The little _Siren_ went with her for company. But the weather proved stormy, and it was not until the 15th that they were able to carry out their plan. About noon they came in sight of the spires of the city of Tripoli. Decatur did not wish to reach the _Philadelphia_ until nightfall, but he was afraid to take in sail, for fear of being suspected; so he dragged a cable and a number of buckets behind to lessen his speed. After a time the _Philadelphia_ came in sight. She was anchored well in the harbor, under the guns of two heavy batteries. Two cruisers and a number of gunboats lay near by. It was a desperate and dangerous business which Decatur and his tars had taken in hand, but they did not let that trouble them. At about ten o'clock at night the _Intrepid_ came into the harbor's mouth. The wind had fallen and she crept slowly along over the smooth sea. The _Siren_ stayed behind. Her work was that of rescue in case of trouble. Straight for the frigate went the devoted crew. A new moon sent its soft lustre over the waves. All was still in city and fleet. Soon the _Intrepid_ came near the frigate. Only twelve men were visible on her deck. The others were lying flat in the shadow on the bulwarks, each with cutlass tightly clutched in hand. "What vessel is that?" was asked in Moorish words from the frigate. "The _Mastico_, from Malta," answered the pilot in the same tongue. "We lost our anchors in the gale and were nearly wrecked. Can we ride by your ship for the night?"
