The Battle of Mazagran was a combat between Arab and Berber forces against French troops during the French conquest of Algeria. The small French contingent, holed up in a fortification at Mazagran, near the port city of Mostaganem, withstood several days of assault by `Abd al-Qādir's troops. Unaware that the French defenders were running short of gunpowder, Abdal-Qādir's troops withdrew after several days of ineffectual activity.
