Geoffrey II of Anjou
In 1058 Geoffrey was visited by the king in Anjou. The two planned their next attacks on Normandy. In August of that year the two led a combined force into Normandy to pillage and burn what they could. At a crossing of the Dives River their force was caught by the rising tide. Geoffrey and the king were on the other side when the bulk of their army was attacked and defeated by Duke William. All Geoffrey and the king could do was leave Normandy as fast as they could. The king's death in the summer of 1060 and Geoffrey's death in November of that same year ended their wars.
