Italian war in Soviet Union, 1941-1943

The Italian participation in the Eastern Front during World War II began after the launch of Operation Barbarossa, the German invasion of the Soviet Union, on 22 June 1941. To show solidarity with the Germans, Italian dictator Benito Mussolini ordered a contingent of the Italian Royal Army to be prepared for the Eastern Front and, by early July, an Italian force was in transport. Mussolini did this despite the lack of enthusiasm shown by German dictator Adolf Hitler.

From 1941 to 1943, the Italians maintained two units on the Eastern Front. The first Italian fighting force was a corps-sized unit called the Italian Expeditionary Corps in Russia (Corpo di Spedizione Italiano in Russia, or CSIR). The second force was an army-sized unit which subsumed the CSIR. The second force was called the Italian Army in Russia (Armata Italiana in Russia, or ARMIR) and was also known as the Italian 8th Army.

The Italian Army in Russia suffered heavy losses during the Battle of Stalingrad and was withdrawn to Italy in 1943. Only minor Italian units participated on the Eastern Front past that point.

Constituted on 10 July 1941, the Italian Expeditionary Corps in Russia (Corpo di Spedizione Italiano in Russia, or CSIR) arrived in the southern Soviet Union between July and August 1941. The CSIR was initially subordinated to German General Eugen Ritter von Schobert’s 11th Army. On 14 August 1941, the CSIR was transferred to the control of German General Ewald von Kleist's Panzer Group 1. On 25 October 1941, Panzer Group 1 was redesignated as the 1st Panzer Army. The CSIR remained under von Kleist’s command until 3 June 1942 when it was subordinated to German General Richard Ruoff’s 17th Army.
