Marshal Pietro Badoglio, Governor of Libya from January 1929, after extensive negotiations concluded a compromise with Mukhtar (described by the Italians as his complete submission) similar to previous Italo-Senusite accords. At the end of October, 1929, Mukhtar denounced the compromise and re-established a unity of action among Libyan forces, preparing himself for the ultimate confrontation with General Rodolfo Graziani, the Italian military commander from March 1930. A massive offensive in June against Mukhtar's forces having failed, Graziani, in full accord with Badoglio, Emilio De Bono (Minister of the Colonies), and Benito Mussolini, initiated a plan to break the Libyan Mujāhideen:100,000 population of Jebel Akhdar would be relocated to concentration camps on the coast, and the Libyan-Egyptian border from the coast at Giarabub would be closed, preventing any foreign help to the fighters and depriving them of support from the native population. These measures, which Graziani initiated early in 1931, took their toll on the Senusite resistance. The rebels were deprived of help and reinforcements, spied upon, hit by Italian aircraft, and pursued on the ground by the Italian forces aided by local informers and collaborators. Mukhtar continued to struggle despite increased hardships and risks, but on 11 September 1931, he was ambushed near Slonta.
