The earlier conflict restarted after the truce between the two kings expired (just long enough to see the harvest in, according to the chronicler Roger of Hoveden).

Both kings invaded and pillaged the other's territory, causing great suffering to the local population by having their captives' eyes put out.

The two forces met, after the Frankish army — which was superior in numbers — changed directions and advanced towards Gisors.

The French fled the field by crossing the bridge at the town of Gisors, which broke down under their weight, "and the king of France, as we have heard say, had to drink of the river" Richard reported to the Bishop of Durham; with the French king struggling for his life, his troops managed to pull him out of the water.

Allegedly, before Gisors, Richard coined as countersign the parole of the day to tell friend from foe, "Dieu et mon droit", a denial of his fealty to the King of France.
