The King and Queen still had the support of much of the nobility and withdrew to the north to commence a campaign of ravaging York and the Nevilles' estates. This forced York, Salisbury and Rutland to move north on 9 December to suppress the Lancastrians. Mowbray remained in London with Salisbury's and York's sons, the Earls of Warwick and March. York and Salisbury's expedition ended in disaster. Choosing to engage a Lancastrian army outside the duke's castle at Sandal, the Yorkists were crushed at the Battle of Wakefield on 30 December. York Rutland and Salisbury, died in or soon after the battle. The Queen's army made its way south towards London. Mowbray, Warwick and his brother John Neville, Lord Montagu, marched north to intercept the approaching Lancastrians. Mowbray brought King Henry with them. The armies clashed on 17 February 1461 outside St Albans, where the Yorkists were defeated. Mowbray and Warwick abandoned the King to his wife and her supporters, and retreated to London before the victorious Lancastrian army could reach the city.
