William, the duke of Normandy: 1048 to 1060

Count Geoffrey agrees to a parley, but only if both of you take your grievances before king Henry.
You agree and ride with Anjou to Paris.
You don't trust Anjou, and decide to make a sneak attack on his army: raising the siege of Domfront, you ride southwest toward where your scouts have told you the Angevin army lies encamped some miles away.
Rather than trust count Geoffrey you decide to attempt the surprise attack on Alençon instead.
