In 1941–1942, the African FFF slowly grew in strength and even expanded operations north into Italian Libya. In February 1941, Free French Forces invaded Cyrenaica, again led by Leclerc, capturing the Italian fort at the oasis of Kufra. In 1942, Leclerc's forces and soldiers from the British Long Range Desert Group captured parts of the province of Fezzan. At the end of 1942, Leclerc moved his forces into Tripolitania to join British Commonwealth and other FFF forces in the Run for Tunis.
