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, who broke through the American lines and escaped unhurt. In the meantime a second party of the Americans had advanced, and commenced a sharp fire on those in possession of the ground, mistaking them for the British picket. This fire continued for nearly half an hour, when, being undeceived, both parties hastily retreated, leaving behind five killed and as many wounded. The troops immediately afterwards returned to Champlain, and on 23 November to Plattsburgh, when the militia were disbanded, and the 11th U.S. regiment was sent to Burlington, with the 9th, 21st, and 25th, all under the command of Brig. Gen. John Chandler of Maine.

The Vermont non-intercourse act, passed 6 November 1812, provided "that all officers, civil and military, of this State, shall aid in currying this act into full force"; and therefore, immediately after the return of the 11th U.S. regiment and militia from Pittsburgh, a vigorous enforcement of the act along the northern boundary line of Vermont was commenced. In this work Col. Isaac Clark of the 11th Infantry regiment, and Lieut. Col. Edward Fifield of the militia, were conspicuous.

10 February 1813, the Secretary of War ordered Gen. Dearborn to move the two brigades at Plattsburgh (Bloomfield's and Chandler's, numbering 2480 men,) to Sackett's Harbor; and 14 March Dearborn complied, leaving no troops at Plattsburgh, and only the 11th regiment of infantry and a company of artillery at Burlington. The 11th Infantry regiment was not full at that time, but was to be filled in a few weeks.

13 May 1813, five hundred men from the 11th Infantry regiment, being the first battalion, were ordered to Sackett's Harbor, and on 31 May left Burlington under the command of Lieut. Col. Timothy Upham.

This 11th Infantry Regiment participated in the following: the Battle of Crysler's Farm; the Second Battle of Lacolle Mills; the Raid on Port Dover, the Capture of Fort Erie, the Battle of Chippawa, where Colonel John B. Campbell (9 April to 28 August 1814), was mortally wounded and the 11th Infantry came under command of Maj. John McNeil, who was breveted Lt. Col. for his actions; and the Battle of Lundy's Lane.

The third colonel of the regiment, Moody Bedel (4 September 1814 to 17 May 1815), became a brigadier general during the War of 1812. He was the son of Timothy Bedel a commander during the American Revolution. Moody Bedel's son John Bedel was a brigadier general of volunteers during the American Civil War.

It was consolidated May–October 1815 with a company of the 25th Infantry and a company each of the 27th, 29th, and 37th Infantry to form a company of the 6th Infantry. The present 6th United States Infantry traces its lineage back to this 11th Infantry Regiment. for the First U.S. 6th Infantry Regiment see: 2nd Infantry Regiment (United States)

The official U.S. Army lineage of the present 11th Infantry Regiment starts with the Civil War in 1861.
