Within a week of Italy's 10 June 1940 declaration of war upon Britain, the British Army's 11th Hussars (assisted by elements of the 1st Royal Tank Regiment and supported by Gladiators of No. 33 Squadron and Blenheims of No. 211 Squadron) captured Fort Capuzzo. Nearly two months later, the Italian 1st Blackshirt Division recaptured it during an attack which reached Sidi Barrani, Egypt on 13 September 1940.
During Operation Brevity, the Fort changed hands briefly on 15–16 May, but ultimately remained in German-Italian possession when the operation failed and the attacking British Brigade group withdrew. The fort was retaken by the New Zealand Division on 22 November 1941, during Operation Crusader.
