William, the duke of Normandy: 1048 to 1060

Count Enguerrand agrees to a parley beneath the walls of Arques castle, where William of Talou can join in. There is little to be gained by such an attempt. Your enemies are determined to support Talou's cause: it is a family affair, after all, and loyalties to kin outweigh past alliances through marriage. (Enguerrand was once married to your sister, but the pope made them split on the old bugbear of consanguinity.)

Your chance to assert the initiative is lost in talk. The Ponthievin army remains in close contact with your mobile force, hampering your every move until Henry's army arrives in the neighborhood, with count Geoffrey's Angevins. Your forces are utterly outclassed now.
Retreat to Rouen.
Offer battle.
Offer peace terms. King Henry will only accept a parley with you if you come to his camp, on the assurance that you will not be harmed in any way.
