Libya. Leclerc's attention was drawn to two Italian outposts in the desert, Murzuk in southwestern Libya and Kufra in the southeast. Both were over from his base at Fort Lamy in Chad. He started with a small raid on Murzuk by eleven men of the Régiment de Tirailleurs Sénégalais du Tchad (RTST) and two troops of the British Long Range Desert Group (LRDG) on 11 January 1941. In February, he led a much larger operation that captured Kufra. After the battle, he had his men swear an oath known today as the Serment de Koufra ("Oath of Kufra"): Leclerc learnt a great deal about how to handle and supply a force advancing across the desert, and was rewarded with the British Distinguished Service Order. He began planning a far more ambitious advance into Libya. This was delayed by a year due to Generalfeldmarschall Erwin Rommel's defeat of the British Eighth Army in the Battle of Gazala, and the subsequent German and Italian advance into Egypt. Leclerc was promoted to Général de brigade in August 1941, and pinned two metal stars captured from the Italians on his kepi. De Gaulle ordered the plan for an advance into Libya to be put in motion in the wake of the Eighth Army's victory in the Second Battle of El Alamein in November 1942. Leclerc set out from Fort Lamy on 16 December 1942 with 500 European and 2,700 African troops in 350 vehicles. He captured Sebha on 12 January 1943, and Mizdah on 22 January. He reached Tripoli on 26 January, where he was greeted by the Eighth Army's commander, General Bernard Montgomery. Leclerc's command, now reinforced by the Greek Sacred Squadron, and known as L Force, covered the Eighth Army's inland flank during its advance into Tunisia. L Force beat off a German counterattack on 10 March, and participated in the attack on the Mareth Line. Western Europe After the fighting in North Africa ended, Leclerc's L Force, now about 4,000 strong, became the 2e Division Française Libre (2e DFL). In June 1943, de Gaulle informed him the 2e DFL would be re-equipped by the Americans as an armoured division, the 2e Division Blindée (2e DB). It was often called La Division Leclerc. Although organised along American lines, its units had French titles. The non-white units were transferred elsewhere. The remainder of 2e DFL became the Regiment de Marche du Tchad (RMT),
