Though a brevet captain, Worth continued with Scott in the important position of aid-de-camp, and served in that capacity at Lundy's Lane, in the battle of July 25th, 1814. On that occasion he distinguished himself in the highest degree, and won the reputation his whole subsequent career has confirmed, of coolness, decision, and activity. During this engagement the whole British force was thrown on the 9th foot, commanded by the veteran Lieut. Col. Leavenworth. This officer sent for aid to Gen. Scott, who on that occasion gave Gen. Taylor the example after which that gallant general acted at Buena Vesta. He repaired to the menaced point with the strong reinforcement of his own person and aid, and had the proud satisfaction of seeing the attacking column beaten back, and the general who led it made prisoner. At the moment of success, however, both Scott and Capt. Worth fell wounded severely. The country appreciated their services, and each received from Mr. Madison the brevet of another grade, with date from the day of the battle. Major Worth soon recovered, but, attached to Gen. Scott's person, accompanied him southward, as soon as the wound of the latter enabled him to bear the fatigue of travel. When peace came Worth was a captain in the line and a major by brevet, with which rank he was assigned to the military command of the corps of Cadets at West Point. This appointment, ever conferred on men of talent, is the highest compliment an officer of the service of the United States can receive in time of peace. To Worth it was doubly grateful, because he was not an _eleve_ of the institution. Ten years after the battle of Niagara, Major Worth was breveted a lieutenant colonel, and when in 1832 the ordnance corps was established, he became one of its majors. In July, 1832, on the organization of the 8th infantry, Lieut. Col. Worth was appointed to its colonelcy. Hitherto we have seen Worth in a subordinate position, where he was unable to exhibit the highest qualification of a soldier, that of command. Since his entry into the service he had been either an officer of the staff, or separated from troops. He was now called on to participate in far more stirring scenes. The war against the Seminoles in Florida had long been a subject of great anxiety to both the government and the people, and thither Worth was ordered, after a brief but effective tour of service on the northern frontier, then infested by the Canadian insurgents. At first he acted subordinately to the late Gen. Armistead, but, on the retirement of that officer, assumed command. The war was prosecuted by him with new vigor, and the Indians defeated ultimately at Pilaklakaha, near the St. John, April 17, 1842. This fight was virtually the termination of the war, the enemy never again having shown himself in force. Gen. Worth was highly complimented for his services on this occasion, and received the brevet of brigadier general.
