Eastern Fleet - Early War Years

Early War Years

Until 1941, the main threat to British interests in the region was the presence of German commerce raiders (auxiliary cruisers) and submarines. The fleet had trade protection as its first priority and was required to escort convoys and eliminate the raiders. The Germans had converted merchant ships to act as commerce raiders and allocated supply ships to maintain them. The location and destruction of these German raiders consumed much British naval effort until the last raider - Michel - was sunk in October 1943.

On 10 June 1940, the entry of Italy into the war introduced a new threat to the oil supply routes from the Persian Gulf, which passed through the Red Sea to the Mediterranean. The Italians controlled ports in Italian East Africa and Tiensin, China. The Italian Royal Navy (Regia Marina) presence in the Red Sea, Indian Ocean, and the western Pacific Ocean consisted of destroyers, submarines, and a small number of armed merchantmen. The majority of these were based at Massawa in Eritrea as part of the Italian Red Sea Flotilla, primarily seven destroyers and eight submarines. Damage to British destroyers at this time included HMS Kimberley which was crippled by Italian shore batteries.

The Italian naval forces in East Africa were caught in a vice. To put to sea invited heavy British reaction, while to stay in ports threatened by British and Commonwealth forces became impossible. In 1941, during the East African Campaign, these ports were captured by the British.
