Battle of Cocherel

The French crown had been at odds with Navarre (near southern Gascony) since 1354. In 1363 the Navarrese used the captivity of John II of France in London and the political weakness of the Dauphin to try to seize power. As England was supposed to be at peace with France the English military forces used to support Navarre were drawn from the mercenary routier companies, not the king of England's army, thus avoiding a breach of the peace treaty.

In the past when the opposing army had advanced then they would be cut to pieces by the archers, however in this battle, du Guesclin managed to break the defensive formation by attacking and then pretending to retreat, which tempted Sir John Jouel and his battalion from their hill in pursuit. Captal de Buch and his company followed. A flank attack by du Guesclin's reserve then won the day.
