Following their victory at Towton in 1461, The House of York continued to triumph. By 1470, however, relations between Edward and his lieutenant, Eari of Warwick, had broken down and Warwick had joined the Lancastrian cause. On 14 April 1471 at Barnet, Edward defeated and killed Warwick. On the same day Henry VI's wife and son, Queen Margaret and Prince Edward, landed at Weymouth. Learning of the disaster, they united with Warwick's army and made a stand at Tewkesbury. Edward IV bombarded Somerset's division, who reacted with a surprise attack on the Yorkist line. However, Edward IV counterattacked and routed Somerset's men. The Lancastrians fled. This title examines how, after Tewkesbury, the Lancastrian cause had been virtually wiped out.
