The Auto-Saharan Companies (Compagnie Auto-Avio-Sahariane) were Italian military units specialised in long range patrols of the Sahara Desert. The units operated from the late 1930s to the Italian surrender in 1943.
The Saharan companies were first formed in 1923 with the purpose of patrolling the space among the Italian forts in the Libyan Sahara desert. In 1938 the five existent companies were reorganized as motorized units with their own aerial support. The companies received new off-road vehicles and a light aircraft section (manned by Regia Aeronautica personnel). In March 1941 five new Compagnie Sahariane were formed.
Two aircraft sections (Sezioni Aeroplani) were formed in order to operate together with the Saharan companies. Each section had four planes for reconnaissance and liaison, the most effective of which was the twin engined Caproni Ca.309 Ghibli.
In concept, the Auto-Saharan Company was similar to the British Long Range Desert Group (LRDG) which was created (as a partial copy) in 1940, except that the Company also had the support of its own air arm to assist in long range reconnaissance and ground attack.
A small battle with the British LRDG happened on January 31, 1941 near the oasis of Kufra, in southeastern Italian Libya. The British were intercepted by the Compagnia Autosahariana di Cufra in the Gebel Sherif valley. The LRDG had one man killed and three men captured, including Major Clayton, and three trucks destroyed during the battle. The Italians losses were five killed and three wounded, and one truck was abandoned. Four member of the LRDG escaped by walking 200 miles (320 km) to safety in ten days with no food and only a 2-imperial-gallon (9.1 L) water can between them. The patrol arrived back in Egypt on 9 February; it had covered about 4,500 miles (7,200 km), experiencing the loss of six trucks, four by enemy action and two by mechanical breakdowns. One vehicle with a broken rear axle had been towed about 900 miles (1,400 km) before it could be repaired. Total casualties were three dead and three captured. Major Clayton was awarded the Distinguished Service Order.
The "Auto-avio-Sahariane Compagnie" fought against the LRDG in 1941 and 1942, but their activity was reduced because of lack of gasoline. Under Del Pozzo leadership these units did an incursion inside Egypt and in November 1942 defeated the British raiders in two small skirmishes. After El Alamein they lost their Libyan troops, but they were enlarged to 5000 men (all Italians) in Tunisia as "Raggruppamento Sahariano" under general Mannerini orders
One German narrator says that there were ‘about five battalions and three light batteries’ (in the Raggruppamento Mannerini), but this estimate is certainly too low for artillery units. Another detailed estimate shows that there were about ten companies of sorts and eight batteries, very mixed in nature and calibre. Probably the total strength (initially) was something short of 2500, which is the highest figure given anywhere. It was known to the Intelligence service—and so to NZ Corps—that the troops in the Gap were all Italian.
In 1940 a Compagnia Sahariana, according to regulations, was composed of four platoons (one HQ, two motorized and one machine guns), the strength was 4 officers, 7 NCOs and 32 Italian enlisted together with 77 Libyan enlisted. The company operated with 16 AS37 off-road cars and 3 trucks (FIAT 634). One of the AS37 in the HQ platoon was equipped with radio in order to maintain real time liaison with the aircraft during operations.
In 1942 the organisation of the companies was revised, other than the HQ platoon, a company was made up with one infantry motorized platoon, one machine guns motorized platoon, one 20mm cannons motorized platoon and one 47/32 anti-tank cannons motorized platoon. They could rely on 7 off-road vehicles (AS.37 or AS.42) and 10 trucks (LANCIA 3 RO). A single company was manned by 5 officers, 3 NCOs, 2 Italian enlisted and 133 Libyan enlisted.
The most common and versatile weapon used by Auto-Saharan Companies was the Cannone-Mitragliera Breda 20mm mod.35. Following the successful experience made by Italian units operating together with the nationalists in the Spanish civil war, the installation of 20mm Breda machineguns on medium trucks was begun in 1939. The gun-carriage, without its legs, was made fast to the vehicle with a pin. During the war the 20mm Breda machineguns utilized different kind of ammunitions, initially were available HE air defence ammunitions and HE piercing ammunitions. At the end of 1942 armor piercing incendiary ammunition was also in use. The standard Italian anti-tank cannon Ansaldo-Bohler 47/32 was used by Saharan motorized units mainly mounted on revolving platforms on LANCIA 3 RO lorries but also on AS.37 or AS.42. The 47/32 was able to fire various kind of HE, piercing and piercing-exploding ammunitions. Maximum useful range as an anti-tank cannon was 700 meters, the piercing power at 650 meters with 30 degrees impact angle was 40 mm, at 1600 meters the piercing power was reduced to only 30 mm. Since the beginning of the war, due to the progress in tank design, the usefulness as an anti-tank weapon of the 47/32 was very limited, and it proved effective only against light tanks and armoured cars.
The vehicles most commonly used by Saharan Companies were the following:
- Trattore Leggero SPA TL.37 “Libia”. The TL.37 was a versatile four-wheeled artillery tractor with all-wheel steering. The vehicle, designed in 1937, was powered by a four-cylinder gasoline engine, the 52 hp SPA 18R. It had a maximum speed of 38 km/h (24 mph) and could carry 800 kg (1,800 lb). It could carry six passengers in two front seats and four back seats. The “Libia” variant differed from the basic TL.37 artillery tractor in having a larger fuel tank and specially designed Pirelli tires. Some TL.37 “Libia” variants were armed with a 20mm Breda cannon or Cannone da 47/32 M35 anti-tank gun.
- Autocarro Sahariano SPA AS.37. This vehicle, also based on the TL.37 artillery tractor, was capable of higher speed (50 km/h); the cargo capacity was also increased about 25% to 4,190 kg. The AS.37 had a flat truck bed with two benches facing each other. Starting in 1941, some of them were armed with a 20mm Breda cannon.
- Camionetta Desertica SPA-Viberti AS.42, this vehicle, specifically designed to operate in the desert, was a four-wheel-drive car that entered into service with Saharan units in November 1942. It was built on the same chassis as the AB.40/41 armoured car but it was not armoured. It was powered with a 100 hp gasoline engine and reached a maximum speed of 85 km/h. This easily recognizable vehicle had racks on the sides to carry 24 jerrycans (mostly fuel) and carried a spare tire on the front hood. It could accommodate a crew of six and weapons such as the 20mm Breda cannon, the Cannone da 47/32 M35, the 20mm Solothurn S-18/100 anti-tank rifle, and up to three Breda mod. 37 machineguns. The AS.42 was 1.49 meters high, 5.20 meters long and 1.80 meters wide.
- Camion FIAT 634. This truck, the military variant of the civil FIAT 632, was 3.24 meters high, 7.43 meters long, and 2.40 meters wide. It had six wheels, two on the front axle and four on the rear axle. It had a maximum load of 7640 kg and a maximum speed of 40 km/h. It was powered by a diesel engine. It was used by Saharan units to transport troops or supplies.
- Camion Lancia 3 RO. This very effective and reliable vehicle was another six-wheeled truck like the FIAT 634. More than 12,000 were built for the Regio Esercito. It was powered by a 5 cylinder, 93 hp diesel engine, giving it a speed of 50 km/h. It was 3 meters high, 7.25 meters long, and 2.35 meters wide. It was able to carry up to 8 tons of cargo. The 3 RO used by Saharan companies had a 20mm Breda cannon or 47/32 anti-tank gun on a rotating platform on the flatbed.
Every "compagnia" was supported until November 1942 by 3 airplanes, model Caproni Ca.309 and nicknamed "Ghibli". In Tunisia the "Raggruppamento sahariano" had no air support, but one Ca.309, left in Libya because damaged, was repaired and remained active in Africa until May 1943.
The Ca.309 (with a 3 crew) was a low-wing cantilever monoplane with a piston engine fitted to each wing, and was intended to serve as a reconnaissance and ground-attack aircraft. It had 3 × 7.7 mm (.303 in) Breda SAFAT machine guns and could drop bombs for up to 330 kg.
