William, the duke of Normandy: 1048 to 1060

Count Geoffrey pursues you right back across the Norman border. Your reduced, weary army is at risk of being caught between the royal army and the pursuing Angevins. But you manage to gain the security of Rouen: by a stroke of good luck, king Henry was dilatorious in moving toward you.

With Rouen secured, you are too strong to reduce without a lengthy siege. There are still many Normans at large who support you over William of Talou. While you defy your enemies, the duchy is given over to scores of small-scale fights and and much pillaging of the open countryside. Henry's confidence wanes, and he decides to withdraw until he can gain reinforcements. You now have a choice to make:
Remain secure at Rouen and prepare for a lengthy siege.
Gather your immediate forces and besiege your uncle William at Arques.
