On 23 October 1942, Aboulker was among the resistance leaders who met with General Mark Clark in Vichy Morocco. The Americans agreed to supply weapons and radios, which were landed on 5 November. 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.
