when did the us and britain invade italy
Allied invasion of Italy The Allied invasion of Italy was the Allied amphibious landing on mainland Italy that took place on 3 September 1943 during the early stages of the Italian Campaign of World War II. The operation was undertaken by General Sir Harold Alexander's 15th Army Group (comprising General Mark W. Clark's Fifth Army and General Bernard Montgomery's British Eighth Army) and followed the successful invasion of Sicily. The main invasion force landed around Salerno on 9 September on the western coast in Operation Avalanche, while two supporting operations took place in Calabria (Operation Baytown) and Taranto (Operation Slapstick).
Regia Marina On 10 June 1940, following the German invasion of France and the lowlands, the Kingdom of Italy declared war on France and the United Kingdom and entered World War II. Italy went to war with the fourth largest navy in the world.[citation needed] Italian dictator Benito Mussolini saw the control of the Mediterranean Sea as an essential prerequisite for expanding his "New Roman Empire" into Nice, Corsica, Tunis and the Balkans. Italian naval building accelerated during his tenure. Mussolini described the Mediterranean as "Mare Nostrum" (Our Sea).[3]
