Hostilities began in April when the Counts of Flanders and Boulogne invaded Normandy from the east, the King of France and young Henry from the south, while the Bretons attacked from the west. Each of the assaults ended with failure: the Count of Boulogne was killed, Louis was defeated and kicked out of Normandy, and the Bretons were routed with great loss of life and treasure. William the Lion's attacks in the north of England were also a failure. Negotiations were opened with the rebels in Normandy between father Henry II and son young Henry, to no avail.
