Italian Co-belligerent Army
The Italian Co-belligerent Army (Esercito Cobelligerante Italiano), Army of the South (Esercito del Sud), or Italian Liberation Corps (Corpo Italiano di Liberazione) were names applied to various division sets of the now former Royal Italian Army during the period when it fought on the side of the Allies during World War II from September 1943 onwards. During the same period, the pro-allied Italian Royal Navy and Italian Royal Air Force were known as the Italian Co-belligerent Navy and Italian Co-belligerent Air Force respectively. From September 1943, pro-Axis Italian forces became the National Republican Army of the newly formed Italian Social Republic.
The Italian Co-belligerent Army was the result of the Allied armistice with Italy on 8 September 1943; King Victor Emmanuel III dismissed Benito Mussolini as Prime Minister in July 1943 following the Allied invasion of Southern Italy, and nominated Marshal of Italy (Maresciallo d'Italia) Pietro Badoglio instead, who aligned Italy with the Allies.
The Italian Co-belligerent Army fielded between 200,000 and 260,000 troops in the Italian Campaign, of whom 20,000 (later augmented to 50,000) were combat troops and between 150,000 and 190,000 were auxiliary and support troops. On the whole, the Italian Co-Belligerent Army made up 1/8 of the fighting force and 1/4 of the entire force of 15th Army Group of the Allied Forces.
A corps (1° Raggruppamento Motorizzato) was then created. The unit included elements of two divisions that had previously been part of the Regio Esercito: the 18 Infantry Division Messina and the 58 Infantry Division Legnano The corps was composed of 295 officers and 5,387 men.
The corps' first engagement was in the Cassino sector at Monte Lungo. This action did much to remove the Allied distrust of Italian soldiers fighting on their side. The unit suffered heavy casualties and was judged to perform satisfactorily.
Following service with the American Fifth Army, commanded by Mark W. Clark, and re-organization, command of the 1° Raggruppamento Motorizzato was transferred to the Polish II Corps on the extreme left of the British Eighth Army under the command of Oliver Leese.
Italian Liberation Corps
On 17 April 1944, the formation (now 22,000 men strong) assumed the name Italian Liberation Corps (Corpo Italiano di Liberazione, or CIL). The continuous influx of volunteers made it necessary to form further formations. The CIL was organized in two new divisions: The "Nembo" and the "Utili." The "Nembo" Division was formed around the old Royal Army's parachute division of the same name. The "Utili" Division was formed around the First Motorized Combat Group and was named after its commander, General Umberto Utili. In early 1944, a 5,000 man force of Italians fought on the Gustav Line around Monte Cassino and acquitted itself well. The Italians once again suffered heavy casualties.
Italian Co-belligerent Army from late 1944 to 1945
After the battle of Filottrano (July 1944), Italian troops were sent to the rear lines to rest and re-train. In the meantime they were re-kitted with standard British/Commonwealth equipment including Battle Dress uniforms and helmets (mostly new and not taken off corpses as hearsay sometimes has it).
By early 1945 the CIL had outgrown itself. It was used as the nucleus for six separate Combat Groups (Gruppi di Combattimento): "Cremona", "Legnano", "Friuli", "Mantova", "Piceno", and "Folgore". Each Combat Group was the equal to a weak division and was equipped with British uniforms, materiel and weapons. The established strength for each was 432 officers, 8,578 other rank, 116 field guns, 170 mortars, 502 light machine guns, and 1,277 motor vehicles. The Combat Groups were given the names of old Royal Army divisions and followed the component numbering system of the component regiments to some extent. These groups were attached to various American and British formations on the Gothic Line. The following is the "order of battle" of the Italian Co-belligerent Army as of April 1945.
Each infantry regiment fielded three infantry battalions, a mortar company armed with British ML 3 inch mortars and an anti-tank company armed with British QF 6 pounder guns. The artillery regiments consisted of four artillery groups with British QF 25 pounder guns, one anti-tank group with British QF 17 pounder guns and one anti-air group armed with British versions of the Bofors 40mm gun.
