Margaret of Anjou had returned to England with Anne Neville and Prince Edward in April, bringing additional troops. At the Battle of Tewkesbury, Edward IV crushed this last Lancastrian army. Prince Edward was killed in or shortly after the battle, and Anne Neville was taken prisoner. She was taken first to Coventry and then to the house of her brother-in-law the Duke of Clarence in London, while her mother Anne Beauchamp, Warwick's wife, sought sanctuary in Beaulieu Abbey. When the crisis settled down and the Countess wished to be restored to her estates, Edward IV refused her safe conduct to plead her case; she wrote to Queen Elizabeth and several others to no avail.
