With his father, the earl of Salisbury, Warwick supported Richard of York in his bid for the protectorship of Henry VI (1454) and took up arms when York lost his office. Warwick was largely responsible for the Yorkist victory at the first battle of St. Albans (1455) and was appointed to the strategic post of governor of Calais. In 1459 when fighting broke out again, York, Salisbury, and Warwick were forced to flee the country, but in 1460 they returned and captured the king at the battle of Northampton. The queen, Margaret of Anjou, raised an army in the north, defeated and killed York and Salisbury at Wakefield (1460), and defeated Warwick and recaptured Henry at the second battle of St. Albans (1461). But York's son, Edward, won the battle of Mortimer's Cross (1461), entered London, and was proclaimed king as Edward IV.
