The Lancastrians missed a chance to bring Warwick to battle instead being content to retire, leaving behind only a token force which surrendered the next day. By May 1463 Alnwick was in Lancastrian hands for the third time since Towton, betrayed by Grey of Heton who tricked the commander, Sir John Astley. Astley was imprisoned and Hungerford resumed command. After Montagu's triumphs at Hedgeley Moor and Hexham in 1464 Warwick arrived before Alnwick on 23 June and received its surrender next day. By the following decade, the 4th Earl of Northumberland had pledged fealty to Edward IV and the castle was returned to the Percys.
