Battle of Bouvines
By June 1214, John had the support of the houses of Lusignan, Mauléon, and Thouars, but when John advanced into Anjou, capturing Angers on 17 June, the desertion of his Poitevin allies forced a retreat back to La Rochelle. On 27 July, John's German allies lost the Battle of Bouvines, with many prisoners taken, including the Earl of Salisbury. On 18 September, John and Philip agreed to a truce that would last until Easter 1220. In October 1214, John returned to England.
