Almost a year earlier, in July 1469, an army loyal to the Yorkist king, King Edward IV was defeated at the Battle of Edgecote Moor by Richard Neville, 16th Earl of Warwick, his disaffected former supporter; Edward himself was subsequently captured in Olney, Buckinghamshire. However, with the help and support of his brother Richard, Duke of Gloucester, he had by now regained power. Despite the nominal reconciliation of Warwick and the king, by March 1470 Warwick found himself in a similar position to that which he had been in before the battle of Edgecote. He was unable to exercise any control over, or influence, Edward's policies. Warwick wanted to place another of the King's brothers, George, Duke of Clarence, on the throne so that he could regain his influence. To do so, he called on former supporters of the defeated House of Lancaster.
