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 Anglo-Gascon infantry suffered heavy losses, and the battle resulted in a decisive French victory. 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.
