It is a moment of terrible suspense. The least mistake, the least disturbance or excitement, must mean detection, and detection now will seal the fate of all. But Decatur has that perfect calmness and clearness of judgment which is the highest bravery. There is no flurry. In his low quiet voice he orders the boat manned. His calmness calms the men, and with an air of lazy indolence they get in and take the oars, carrying a rope to another boat which meets them from the frigate. The work is done in silence; the ends are fastened, and the boat returns. The hawser is passed along the deck; the crew lying on it pull noiselessly, and the ketch slowly, slowly but surely, nears her place and lies fast alongside the enemy. Suddenly a piercing cry breaks the stillness. "_Americanos!_ The Americans are upon us!" The enemy has now discovered the disguise. But at the same moment Decatur's voice is heard ringing out, "Board!" and he and Morris, who has been watching him, leap to the enemy's deck. Springing to their feet as one man, the crew follow them, each with his cutlass and pistol. The Tripolitans are panic-struck; for a moment they huddle in a frightened crowd on the forecastle. One instant Decatur pauses to form his men, and then at their head he dashes at the enemy. The few who stay to offer resistance are cut down; one is made prisoner; the rest, driven to the bow, leap from the rail into the water. The ship is now captured, and the victorious crew hurry to their appointed stations. Two parties are told off to the berth-deck, one to the forward store-rooms, and one under Morris to the cockpit. Each prepares its supply of combustibles, and when all is reported ready, the order is given to set fire. This done, each party leaves the ship, but Morris and his men barely escape through the smoke and flame with which the lower deck is already filled. Decatur, standing on the Philadelphia's rail, while the smoke rises around him and the flames are bursting from her ports, waits till the last man has returned, and as the "Intrepid's" head swings off, he leaps into her rigging.
