At Mantes on 9 July 1193, Philip came to terms with Richard's ministers, who agreed that Philip could keep his gains and would be given some extra territories if he ceased all further aggressive actions in Normandy, along with the condition that Philip would hand back the captured territory if Richard would pay homage. To prevent Richard from spoiling their plans, Philip and John attempted to bribe Holy Roman Emperor Henry VI in order to keep the English king captive for a little while longer. Henry refused, and Richard was released from captivity on 4 February 1194. By 13 March Richard had returned to England, and by 12 May he had set sail for Normandy with some 300 ships, eager to engage Philip in war.
