During the Wars of the Roses, castles were infrequently attacked and conflict was generally based around combat in the field. Alnwick was one of three castles held by Lancastrian forces in 1461 and 1462, and it was there that the "only practical defence of a private castle" was made according to military historian D. J. Cathcart King. It was held against King Edward IV until its surrender in mid-September 1461 after the Battle of Towton. Re-captured by Sir William Tailboys, during the winter it was surrendered by him to Hastings, Sir John Howard and Sir Ralph Grey of Heton in late July 1462. Grey was appointed captain but surrendered after a sharp siege in the early autumn. King Edward responded with vigour and when the Earl of Warwick arrived in November Queen Margaret and her French advisor, Pierre de Brézé were forced to sail to Scotland for help. They organised a mainly Scots relief force which, under George Douglas, 4th Earl of Angus and de Brézé, set out on 22 November. Warwick's army, commanded by the experienced Earl of Kent and the recently pardoned Lord Scales, prevented news getting through to the starving garrisons. As a result, the nearby Bamburgh and Dunstanburgh castles soon agreed terms and surrendered. But Hungerford and Whittingham held Alnwick until Warwick was forced to withdraw when de Breze and Angus arrived on 5 January 1463.
