The Battle of Macta was fought on 28 June 1835 between French forces under General Camille Alphonse Trézel and a coalition of Algerian tribes of western Algeria under Emir Abd al-Qadir, who, at the age of 26, waged one of his most famous battles against a superior force.
The French column, which had fought an inconclusive but somewhat bloody battle with Abdul-Qadir a few days earlier, was retreating toward Arzew to resupply when Abdul-Qadir attacked in the marshes on the banks of the Macta River in what is now western Algeria. The French panicked and fled to Arzew in a disorganized rout. The Algerians piled the heads of their defeated French enemies in a pyramid, allegedly hundreds in total.
The disaster led to the recall to France of Trézel and the comte d'Erlon, the first military governor-general of the French possessions in Africa, and helped Abdul-Qadir gain influence over tribes throughout Algeria.
