The 6th Infantry Regiment ("Regulars") was formed 11 January 1812. Zachary Taylor, later the twelfth President of the United States, was a commander of the unit. The motto, "Regulars, By God!" derives from the Battle of Chippawa, in which British Major General Phineas Riall noticed that the approaching regiment had on the uniforms of militia, which the British had defeated at Queenston Heights. Instead, the Americans pressed the attack. Riall is believed to have said, "Those are Regulars, By God!", though the only source of this was opposing U.S. General Winfield Scott.
