 On the night of the Allied landings in North Africa, 7 November 1942, Aboulker led the occupation of the main strategic points in Algiers by 400 members of the Resistance, seizing the central police station, with his deputy Bernard Karsenty and the help of Guy Calvet and Superintendent Achiary.Led by their group leaders, all of the Resistance fighters, with the exception of the reserve officers, neutralized the command centers, occupied strategic positions, and stopped the military officials and civilian supporters of the Vichy government, starting with General General Alphonse Juin, the Commander-in-chief, and Admiral Admiral François Darlan.In the morning, when the XIXth Army Corps of the Vichy Government tried to mobilize to oppose the Allied landings, it had to concentrate its efforts on the Resistance fighters rather than Allied forces.
