He was a staunch adherent of the House of York during the Wars of the Roses, and was knighted by King Edward IV at the Battle of Towton on 29 March 1461. In the same year he was appointed Constable of Norwich and Colchester castles, and became part of the royal household as one of the King's carvers, "the start of a service to the house of York which was to last for the rest of his life."
