In April 1469, a revolt broke out in Yorkshire, under a leader called Robin of Redesdale. Warwick and Clarence spent the summer assembling troops, allegedly to help suppress the revolt. The northern rebels headed for Northampton, intending to link up with Warwick and Clarence. The Battle of Edgcote resulted in a rebel victory which temporarily handed power over to the Earl of Warwick. Edward was taken into custody and held in Middleham Castle. His in-laws Earl Rivers and John Woodville were executed at Gosford Green Coventry on 12 August 1469. However, it soon became clear there was little support for Warwick or Clarence; Edward was released in September and resumed the throne.
