A manuscript by Hyde dated August 8, 1820, titled "Account of the Seneca Indians and Mission", in the collection of the Buffalo Historical Society, explains Hyde's experiences at the mission. After waiting seven months he opened his school. At the annual meeting of the Society on April 7, 1812, it was reported that "his conduct has been prudent and upright and he has succeeded in erecting a school house near the center of the Seneca settlement, where he now resides". He says: "The war took place the next summer … which threw everything into confusion on the frontier".
