I know that the answer to the question "What institution was opposed by the Americans?" is in "For over a century, New Haven citizens had fought in the colonial militia alongside regular British forces, as in the French and Indian War. As the American Revolution approached, General David Wooster and other influential residents hoped that the conflict with the government in Britain could be resolved short of rebellion. On 23 April 1775, which is still celebrated in New Haven as Powder House Day, the Second Company, Governor's Foot Guard, of New Haven entered the struggle against the governing British parliament. Under Captain Benedict Arnold, they broke into the powder house to arm themselves and began a three-day march to Cambridge, Massachusetts. Other New Haven militia members were on hand to escort George Washington from his overnight stay in New Haven on his way to Cambridge. Contemporary reports, from both sides, remark on the New Haven volunteers' professional military bearing, including uniforms.". Can you tell me what it is?
