S1·E26 The Third Part of Henry the Sixth

With Richard Plantagenet on the throne of England, the Yorkists confront the Lancastrians. King Henry agrees to York's demand that he disinherit his son, Edward. Margaret vows to destroy York. She enlists the support of Clifford and others to raise an army. Edward and Richard are informed of their father's murder and unite with Warwick, who proclaims Edward the new Duke of York. They raise an army and defeat the Lancastrians at Towton. Henry, Margaret and their son are forced to flee north. Henry is captured and brought to London, where he is placed in the Tower by the new King Edward. Warwick pledges support to Margaret, releasing Henry from the Tower and reinstating him as King of England. Warwick leaves London to muster his army, during which time Edward returns and recaptures Henry. The forces of Edward and Warwick meet at Barnet. Margaret's forces encounter Edward's for the last time at Tewkesbury, where, after much bloodshed, the Wars of the Roses seem finally to be over.
