In page Henry VI of England:

"

Re-entering England at the end of the year, the English queen in force engaged with the Duke of York at the Battle of Wakefield, 30 December 1460, where York fell. A few weeks later, at the Second Battle of St Albans, 17 February 1461, her forces engaged with the Earl of Warwick, under whose custody her husband was being held. She defeated Warwick and liberated the king. Henry's mental state at the time was such that he had reputedly laughed and sung as the battle raged around him.[citation needed]
