Italian Army (1940–1946)

Italian Army (1940–1946). The Regio Esercito, the army of the Kingdom of Italy, entered World War II in June 1940 as a key component of the Axis powers. Its performance across multiple theatres was marked by significant setbacks, leading to the Armistice of Cassibile in September 1943, which precipitated a fracturing of the force. The subsequent period saw the army split between the Italian Co-belligerent Army fighting alongside the Allies and the Esercito Nazionale Repubblicano loyal to the Italian Social Republic, culminating in its post-war reorganization and eventual dissolution following the establishment of the republic.

Background and pre-war organization

Following the Second Italo-Ethiopian War and intervention in Spain, the Regio Esercito was a large but inadequately modernized force. Its structure, overseen by the Comando Supremo, included numerous infantry divisions, with limited armoured and motorized units like the 132nd Armored Division "Ariete". Doctrine and equipment lagged behind potential adversaries such as the Wehrmacht and British Army, with industry unable to mass-produce modern tanks like the M13/40. Key leaders included Pietro Badoglio and Ugo Cavallero, while the army remained heavily dependent on Libyan and East African colonial forces. Preparations for war were hampered by Benito Mussolini's political ambitions and a lack of strategic coordination with Nazi Germany.

Campaigns of World War II

The army's first major action was the Italian invasion of France, a brief and costly offensive in the Alps. The subsequent Greco-Italian War proved disastrous, requiring German intervention via the Battle of Greece. In the North African campaign, initial advances into Egypt were reversed after the Battle of Sidi Barrani, with major defeats at the Battle of Beda Fomm and the Operation Compass offensive. The East African campaign ended with the loss of Italian East Africa after the Battle of Keren and the Battle of Gondar. On the Eastern Front, the Italian Army in Russia suffered catastrophic losses during the Battle of Stalingrad and the ensuing Operation Little Saturn. The Allied invasion of Sicily in 1943 led to the collapse of the Axis position in Africa and the rapid Allied advance up the Italian peninsula.

Co-belligerent forces and the Italian Civil War

The Armistice of Cassibile announced on 8 September 1943 caused institutional chaos. Forces loyal to King Victor Emmanuel III and Pietro Badoglio formed the Italian Co-belligerent Army, which fought alongside the Allies under commands like the Italian Liberation Corps. Concurrently, the Italian Social Republic (RSI), a German puppet state, established the Esercito Nazionale Repubblicano under Rodolfo Graziani. This split ignited the Italian Civil War, pitting co-belligerent and partisan forces against RSI and Wehrmacht units in brutal campaigns, including the Battle of Monte Cassino and anti-partisan operations in regions like Piedmont. Key engagements involved the Gruppi di Azione Patriottica and the Decima Flottiglia MAS.

Post-armistice reorganization and Allied cooperation

The Italian Co-belligerent Army was progressively re-equipped and reorganized by the Allied military government. Under the supervision of the Allied Control Commission, units such as the Italian Co-belligerent Air Force and the Italian Co-belligerent Navy were also formed. Italian troops, including the 1st Motorized Group and the Legnano Combat Group, fought with distinction in the Italian campaign, notably during the Battle of Monte Lungo and the final Allied offensive. This military contribution was a critical factor in the post-fascist government's diplomatic efforts and the eventual status of Italy as a co-belligerent.

Demobilization and post-war transition

Following the German surrender and the dissolution of the Italian Social Republic, the disparate military forces were unified under the provisional Italian government. The Esercito Nazionale Repubblicano was disbanded, and its personnel faced trials, including those at the Verona trial. The Regio Esercito was formally dissolved after the Italian institutional referendum, 1946, which abolished the monarchy. Its personnel and structures formed the basis of the new Italian Army of the Italian Republic. The Treaty of Peace with Italy, 1947 imposed severe restrictions on the size and equipment of the postwar military, shaping Italy's role in the nascent Cold War and its eventual membership in the NATO alliance.
