Captain John Deserontyon (alt. Captain John, Deseronto, was a Mohawk war chief allied with the British during the American Revolutionary War. He led his people to Upper Canada after the war, settling on land granted by the Crown at the Bay of Quinte in present-day Ontario. In the summer of 1764, he accompanied John Bradstreet in the attack on Fort Detroit at the end of Pontiac's Rebellion. Deseronto went back to the Mohawk valley the following year and met with Sir John Johnson. In 1779 Deseronto led two scouting parties up the Richelieu Valley. In 1780, he took part in Sir John Johnson's raid on the Mohawk valley and he was at the Battle of Klock's Field. In 1781 he led multiple raids into the Mohawk valley destroying mills and cattle and taking prisoners. In the spring of 1782, Deseronto and Captain Isaac Hill destroyed the mill at Little Falls on the Mohawk and took some prisoners. After the war, Deseronto and Joseph Brant, a major war leader of the Upper Castle, met with Governor Frederick Haldimand of Canada to discuss the loss of their land in New York. Deseronto died 7 January 1811 at the Mohawk settlement on the Bay of Quinte in Upper Canada.
