Louis Cook, or Akiatonharonkwen (Mohawk), was an Iroquois leader and commissioned officer in the Continental Army during the American Revolution. During the American Revolutionary War, Cook supported the American colonists and joined their fight against the British. He became the highest-ranking Native American officer in the Continental Army, achieving the rank of lieutenant colonel. He led Oneida warriors, who were allied with the rebels, against the British in some actions. Although the Mohawk and three other of the Iroquois nations sided with the British during the American Revolution, hoping to expel the colonists from their lands, Cook allied with the Thirteen Colonies, as did the Oneida and Tuscarora. Cook was with the Continental Army at Valley Forge in the winter of 1777. During the war, Cook became a personal enemy of Captain Joseph Brant, a Mohawk who supported the British. When each returned to their homes after the war, their personal conflict divided the Mohawk nation. Although too elderly to participate in the War of 1812, Cook followed the United States Army into Canada during the war; he was present at the Battle of Lundy's Lane. He was involved in a skirmish and fell from his horse. The injuries proved fatal; he died in the American camp in October 1814. Cook was given a military salute at his funeral, and was buried near Buffalo, New York.
