The marriage between Edward of Lancaster, the son of Henry VI and Margaret of Anjou, to Anne Neville, the daughter of Richard Neville the Kingmaker was a marriage to cement the agreement that Richard and Margaret would support each other and try to get Henry VI back on the English throne. The marriage took place in France at the Chateau d'Amboise where Margaret and Edward were exiled.

Queen Margaret (wife of Henry VI) and her son Edward the prince of Wales landed at Weymouth on the very same day as the battle of Barnet. Their intention was to assist the Earl of Warwick, but she arrived too late. Determined to avenge the Barnet defeat, the Queen and her army marched north towards Wales and men she could count on to join her army. Edward had thought of this and to cut the Queen off from Wales, had taken control of the bridges across the River Severn.

The Yorkists led by King Edward IV and his brother Richard Duke of Gloucester met the Lancastrians at Tewkesbury. Richard was able to outflank the Lancastrians led by Edmund Beaufort, the self-proclaimed Duke of Somerset. Once Somerset's men had been dealt with, Richard attacked the rear of the Lancastrian line which broke apart and fled. Many of the Lancastrian leaders were caught and killed including Edward the Prince of Wales. Margaret of Anjou, the wife of King Henry VI, was also captured.
