The region took no active part in the ensuing civil wars until the Battle of Tewkesbury in 1471, but both parties to the feud were killed in the civil wars over the next few years. The new Earl of Devon, who had killed Radford, was a thorough supporter of the Lancastrian regime. After the Yorkist victory at the Battle of Northampton in June 1460, he took his troops northwards to Margaret of Anjou in York, where, in April 1461, he was executed by the new king, Edward IV after the Battle of Towton. Bonville's son and grandson had been killed with the Duke of York and the Earl of Salisbury at the Battle of Wakefield in December 1460, and Bonville himself, captured after the Second Battle of St Albans was summarily beheaded – probably, so the chroniclers tell us, after a mock trial directly instigated by the Earl of Devon.
