Siege of Sainte-Suzanne

During the siege, William built a huge military camp known as Beugy on the outskirts of the town, taking advantage of Roman earthworks.

Richer d'Aigle, son-in-law of Richard le Goz, Viscount of Avranches, died in the siege, mortally wounded by an arrow to the eye, and was buried at the monastery of Saint-Sulpice.

Orderic Vitalis records that in January 1086, William de Warenne, 1st Earl of Surrey, wanting to avenge Richer's death, unsuccessfully attacked the castle.

He was accompanied by Richer's brother Gilbert l'Aigle and Baudry II de Guitry.

With many knights killed or captured, William eventually came to terms with the rebels, with Hubert being restored to favor.
