The 11th Infantry Regiment is a regiment in the United States Army. In 2007, the 11th Infantry was reflagged as the 199th Infantry Brigade, as part of the "Transformation of the US Army" effort. Today, the 11th Infantry Regiment is part of the Army's regimental system and is the primary regiment to which many Infantry School units are aligned. Earlier units called "11th Infantry Regiment" The first 11th Infantry Under the authority granted the President by the Act of 16 July 1798, to raise twelve additional regiments of infantry, the first 11th Infantry came into existence in the Army of the United States in January 1799, with Aaron Ogden as Lieutenant Colonel Commandant. It was raised for the "Quasi-War" with France but saw no war service. The Act of 20 February 1800, suspended enlistments for the new regiments. The Act of 14 May 1800, authorized the president to discharge them, and under this authority the 11th Infantry was disbanded 15 June 1800. War of 1812 The second 11th U.S. regiment of infantry was organized on 11 January 1812 when the Congress authorized a strengthening of the Regular Army in preparation for the threatening conflict that became known as the War of 1812. During the summer little was done in Vermont beyond organizing the 11th infantry, which seems to have consisted originally of six companies from Vermont and four from New Hampshire. The army gathered at Plattsburgh, New York, numbering about eight thousand men, of whom nearly one half were Vermonters. Among them was the 11th regiment of regulars under Col. Isaac Clark (12 March 1812 to 27 April 1814). On 16 November 1812 the largest portion moved north under the immediate command of Maj. Gen. Henry Dearborn, then the senior officer of the army, and on 18 November encamped about half a mile south of the Canadian boundary line. The force there assembled numbered three thousand regulars and two thousand militia, while the entire British force on the northern frontier did not exceed three thousand, and of these not more than one thousand were within striking distance of the American army. When Dearborn was prepared to cross the line, the British Major Salaberry also prepared to meet him. Early in the morning of 20 November, a detachment of Dearborn's army forded the La Colle river and surrounded a British guard-house, which was occupied by Canadian militia and a few Indians,
