The naval Battle of Cape Bon took place on December 13, 1941 during the Second World War, between two Italian light cruisers and an Allied destroyer flotilla off Cape Bon, Tunisia. The loss of the two cruisers and their valuable cargoes was a serious defeat for the Regia Marina.

Background[edit]

When Italy declared war in June 1940, the Regia Marina was one of the largest navies in the world but it was restricted to the Mediterranean. The British Empire possessed enough resources and naval might to maintain a strong presence in the area and replace most losses by redeploying ships. This led to caution by the Italian command and a tendency to avoid conflict.[1][page needed] Control of the Mediterranean was disputed by the Regia Marina the Royal Navy and their allies. The sea was vital for the supply of the Italian and German forces in North Africa, as well as the maintenance of Malta as a British offensive base. Without Malta, Britain could not intercept Italian convoys to prevent the supply of Axis forces.[citation needed] Possession of Radar and the breaking of Italian codes, particularly the Boris Hagelin C38 cipher machine used by the Regia Marina, further contributed to British success.[2]

The action[edit]

The Italian 4th Cruiser Division (Vice Admiral[3] Antonino Toscano), consisting of the Da Giussano class light cruisers Alberto da Giussano and Alberico da Barbiano, with the Italian torpedo boat Cigno, sailed from Palermo bound for Tripoli, carrying an urgent deck cargo of nearly 2,000 short tons (1,800 t) of aviation fuel for fighters based in Libya.[4]

The British 4th Destroyer Flotilla, consisting of the British destroyers HMS Sikh, HMS Maori, HMS Legion and the Dutch destroyer Hr. Ms. Isaac Sweers, (Commander G. H. Stokes), had departed Gibraltar on 11 December, to join the Mediterranean Fleet at Alexandria.[4] The flotilla was spotted by an Italian aircraft but Regia Marina headquarters concluded that the British would not be able to reach Cape Bon before the 4th Cruiser Division had passed. On 5 and 8 December the British had intercepted and read Regia Marina signals encrypted by the C 38 machine, that two Italian cruisers were sailing for Tripoli carrying aviation fuel. After the RAF had provided a reconnaissance aircraft to sight the ships as a deception, the 4th Destroyer Flotilla far to the west was ordered on 12 December to increase speed to 30 kn (35 mph; 56 km/h) and intercept the cruisers.[2]

At 2:30 a.m. on 13 December near Cap Bon, the 4th Destroyer Flotilla sighted the Italian cruisers.[4] Arriving from astern under the cover of darkness and using radar, the British ships sailed close inshore and surprised the Italians, launching torpedoes from short range. The land behind the destroyers made it impossible for the Italians to see them and Di Giussano managed to fire only three salvoes.[4] In five minutes both cruisers were sunk; Alberico da Barbiano becoming a blazing inferno. After a brief encounter with the Dutch destroyer Isaac Sweers, Cigno rescued at least 500 survivors, while others reached the coast or were later saved by Italian motor torpedo boats (or MAS boats). 534 men were lost with Da Barbiano, including Toscano and 283 perished with Di Giussano.[citation needed]
