From 8 May to June 26, 1945, the French carried out the Sétif and Guelma massacre, in which at least 30,000 Algerian Muslims were killed. Its initial outbreak occurred during a parade of about 5,000 people of the Muslim Algerian population of Sétif to celebrate the surrender of Nazi Germany in World War II; it ended in clashes between the marchers and the local French gendarmerie, when the latter tried to seize banners attacking colonial rule. After five days, the French colonial military and police suppressed the rebellion, and then carried out a series of reprisals against Muslim civilians. The army carried out summary executions of Muslim rural communities. Less accessible villages were bombed by French aircraft, and cruiser Duguay-Trouin, standing off the coast in the Gulf of Bougie, shelled Kherrata. Vigilantes lynched prisoners taken from local jails or randomly shot Muslims not wearing white arm bands (as instructed by the army) out of hand. It is certain that the great majority of the Muslim victims had not been implicated in the original outbreak. The dead bodies in Guelma were buried in mass graves, but they were later dug up and burned in Héliopolis.
