In 1884-85, Commodore
Robert More-Molyneux commanded the ships in the Red Sea, seemingly the Red Sea Division, during the
Mahdist War. He protected Suakin till the arrival of Sir
Gerald Graham's expedition in 1885. The Royal Navy established a Red Sea
formation as early as 1846, administered by the
Royal Indian Navy. It was subordinate to the
Commander-in-Chief, East Indies until 1883, when it became part of the
Mediterranean Fleet. In 1914 the station came under command of the
Commander-in-Chief Mediterranean Fleet until the end of the war. Following the war the Red Sea was reabsorbed back under the
Commander-in-Chief, East Indies. During the
East African Campaign, the Red Sea Force fought the Italians. British code-breakers of the
Government Code and Cypher School (GC&CS) at Bletchley Park in the UK, deciphered Italian orders of 19 May 1940, coded using
C38m machines, secretly to mobilise the army and air force in East Africa. Merchant traffic was stopped by the British on 24 May, pending the introduction of a convoy system. The Senior Naval Officer Red Sea, Rear-Admiral Murray, operational at Aden since April with the light cruisers and (
Liverpool was replaced by ), was reinforced by the anti-aircraft cruiser , which sailed south with Convoy BS 4, the
28th Destroyer Flotilla comprising ,
Kimberley, and and three sloops from the Mediterranean. The force was to conduct a blockade Italian East Africa (
Operation Begum), attack the Red Sea Flotilla and protect the sea lanes from Aden to Suez. On 21 October 1941 the
Mediterranean Fleet's responsibilities were extended to include the Red Sea and Aden, including the Gulf of Aden. The Mediterranean Fleet thus took over the Red Sea Division of the Red Sea Station, which was located between the
Gulf of Aden and the
Suez Canal, excluding
Suez Port. Three weeks later the responsibilities were adjusted once more. On 14 November 1941 the Senior Naval Officer-in-Charge, Suez, who was based at Port Tawfik (Suez Port) was placed under the command of Rear Admiral Hallifax. Over a hundred kilometres to the north, halfway up the Suez Canal, the
Senior British Naval Officer, Suez Canal Area, based at
Ismailia, remained responsible for all British naval policy questions in regards to the
Suez Canal Company. In January 1944 the station was transferred back from the Mediterranean Fleet to C-in-C East Indies. ==Rear-Admiral, Egypt and Red Sea==
