The Battle of Blanquefort or La Male Journade took place on 1 November 1450 during the Hundred Years' war when a French army drew out Anglo-Gascon forces from Bordeaux in the English-controlled Duchy of Gascony.

The battle was known locally as La Male Journade or in French Mauvaise Journée and marked the beginning of a campaign to drive the English from Gascony.

At the first engagement, at a place called Jallepont, the first French lines slipped away on purpose and led the Anglo-Gascons in pursuit until they reached a cul-de-sac closed by the banks of the Jalle.

It was a trap: Robin Petit-Loup’s archers were hidden in the surrounding woods and decimated the pursuers in nearly an hour of heavy fire.

The magnitude of the losses sounded the death knell for the last hopes of the English to resist the French in southwestern France.
