Battle of Val-ès-Dunes - Background

William had succeeded to his title in 1035, as the seven-year-old illegitimate son of the previous Duke, Robert I. Several of William's kinsmen (including Guy of Burgundy, his cousin) believed themselves to have a better claim to the title, but William had the support of King Henry I and other influential nobles.

In 1046, some of William's enemies decided to finally strike. After an ambush near Valognes on the Cotentin Peninsula failed, the rebel nobles—Guy of Burgundy, Nigel of the Cotentin, Rannulf of the Bessin, Ralph Tesson of Thury, Grimoald of Plessis, and Haimo of Creully—raised an army of about 25,000 men.

After escaping the ambush, William rode directly to King Henry's court in Poissy, and reminded the king that a revolt against his faithful vassal was a revolt against himself. Wanting to protect his vassal and ally, King Henry raised an army of about 10,000 men to march on Normandy.
