In the mountainous region of Jebel Akhdar ("Green Mountain") in 1924, Italian governor Ernesto Bombelli created a counter-guerrilla force that inflicted a severe setback to guerilla forces in April 1925. Mukhtar then quickly modified his own tactics and was able to count on continued help from Egypt. In March 1927, despite occupation of Giarabub from February 1926 and increasingly stringent rule under Governor Attilio Teruzzi, Mukhtar surprised Italian troops at Raheiba. Between 1927 and 1928, Mukhtar reorganised the Senusite forces, who were being hunted constantly by the Italians. Even General Teruzzi recognized Omar's qualities of "exceptional perseverance and strong will power."
