On 27 September, Richard entered Vexin, taking Courcelles-sur-Seine and Boury-en-Vexin before returning to Dangu. Philip, believing that Courcelles was still holding out, went to its relief. Discovering what was happening, Richard decided to attack the French king's forces, catching Philip by surprise. Philip's forces withdrew and attempted to reach the fortress of Gisors. Bunched together, the French knights with king Philip attempted to cross the Epte River on a bridge that promptly collapsed under their weight, almost drowning Philip in the process. He was dragged out of the river and shut himself up in Gisors, having successfully evaded Richard and reinforced the fortress.
