In 1483 the future Richard III of England appointed himself Protector of Edward IV's young son and heir, Edward V, accusing the Woodvilles of plotting against him. Sir Thomas More says that Fogge took sanctuary at this time, and that Richard III was prepared to treat him with favour. Despite this apparent reconciliation, Fogge supported Richard Guildford in Kent against Richard III, a rising in support of Edward V, and became part of the unsuccessful Buckingham's rebellion. The rising was blocked at Gravesend by John Howard, 1st Duke of Norfolk, and the rebel force retreated. Fogge was attainted, and much of his property was granted to Sir Ralph Ashton, who had been loyal to the King, and who was already in conflict with Fogge over a portion of the Kyriell inheritance from Fogge's first marriage. In February 1485 Fogge bound himself to good behaviour and was pardoned, and four of his manors were returned to him.
