A few prominent Mohawk, such as the sachem Little Abraham (Tyorhansera) at Fort Hunter, remained neutral throughout the war. Joseph Louis Cook (Akiatonharónkwen), a veteran of the French and Indian War and ally of the rebels, offered his services to the Americans, receiving an officer's commission from the Continental Congress. He led Oneida warriors against the British. During this war, Johannes Tekarihoga was the civil leader of the Mohawk. He died around 1780. Catherine Crogan, a clan mother and wife of Mohawk war chief Joseph Brant, named her brother Henry Crogan as the new Tekarihoga.
