In 1471 King Edward IV returned from exile with the help of the Duke of Burgundy and at the battle of Barnet the Earl of Warwick was killed. Three weeks later Anne's husband, Prince Edward was killed at the battle of Tewkesbury. Queen Margaret was taken prisoner and sent to the Tower of London.
After the battle Anne was taken by George Duke of Clarence to live with his wife Isabel, Anne's sister. Anne was kept virtually a prisoner as George knew of his brother Richard's intentions to marry Anne. If that happened the inheritance of the Earl of Warwick would have to be divided between George and Richard.
