Mediterranean Fleet in the context of "HMS Gloucester (62)"

At the Congress of Berlin (13 June – 13 July 1878), the major European powers revised the territorial and political terms imposed by the Russian Empire on the Ottoman Empire by the Treaty of San Stefano (March 1878), which had ended the Russo-Turkish War of 1877–1878. The Congress was the result of escalating tensions; particularly British opposition to Russian hegemony over the Ottoman Empire in the Balkans, through the creation of a Russian-aligned 'Greater Bulgaria'. To secure the European balance of power in favour of its splendid isolation achieved after the Crimean War, Britain stationed the Mediterranean Fleet near Constantinople to enforce British demands. To avoid war, Otto von Bismarck, Chancellor of the newly formed German Empire, was asked to mediate a solution that would restore the Ottoman Empire's position as a counterbalance to Russian influence in the Mediterranean and the Balkans, in line with the principles of the 1856 Treaty of Paris.

Attended by delegates from Europe's then six great powers: Russia, Great Britain, France, Austria-Hungary, Italy, and Germany; the Ottomans as well as representatives of four Balkan states (Greece, Serbia, Romania and Montenegro), the Congress culminated in the Treaty of Berlin (13 July 1878). This agreement essentially dismantled the autonomous Greater Bulgarian State envisaged at San Stefano, and reorganised the borders of south-eastern Europe. The main results were the Austro-Hungarian forcible occupation of Bosnia and Herzegovina, the British de facto annexation of Cyprus under false pretenses, and the formal recognition of the self-declared independence of Romania, Serbia and Montenegro; allies of Russia in the previous war. While the settlement averted war, it exacerbated nationalist grievances in the Balkans and deepened the rivalry between Britain and Russia (The Great Game), contributing to long-term regional instability that foreshadowed the Balkan Wars and World War I.

British foreign policy in the Middle East has involved multiple considerations, particularly over the last two and a half centuries. These included maintaining access to British India, blocking Russian or French threats to that access, protecting the Suez Canal, supporting the declining Ottoman Empire against Russian threats, guaranteeing an oil supply after 1900 from Middle East fields, protecting Egypt and other possessions in the Middle East, and enforcing Britain's naval role in the Mediterranean. The timeframe of major concern stretches from the 1770s when the Russian Empire began to dominate the Black Sea, down to the Suez Crisis of the mid-20th century and involvement in the Iraq War in the early 21st. These policies are an integral part of the history of the foreign relations of the United Kingdom.

HMS Greyhound was a G-class destroyer built for the Royal Navy in the 1930s. Greyhound participated in the Norwegian Campaign in April 1940, the Dunkirk evacuation in May and the Battle of Dakar in September before being transferred to the Mediterranean Fleet in November. The ship generally escorted the larger ships of the Mediterranean Fleet as they protected convoys against attacks from the Italian Fleet. She sank two Italian submarines while escorting convoys herself in early 1941. Greyhound was sunk by German Junkers Ju 87 Stuka dive bombers north-west of Crete on 22 May 1941 as she escorted the battleships of the Mediterranean Fleet attempting to intercept the German sea-borne invasion forces destined for Crete.

Prince Philip, Duke of Edinburgh (born Prince Philip of Greece and Denmark, later Philip Mountbatten; 10 June 1921 – 9 April 2021), was the husband of Queen Elizabeth II. As such, he was the consort of the British monarch from his wife's accession on 6 February 1952 until his death in 2021, making him the longest-serving royal consort in history.

Philip was born in Greece into the Greek and Danish royal families; his family was exiled from the country when he was eighteen months old. After being educated in France, Germany, and the United Kingdom, he joined the Royal Navy in 1939, when he was 18 years old. In July 1939, Philip began corresponding with the 13-year-old Princess Elizabeth, the elder daughter and heir presumptive of King George VI. During the Second World War, he served with distinction in the British Mediterranean and Pacific fleets.

HMS Malaya was one of five Queen Elizabeth-class super-dreadnought battleships built for the Royal Navy during the 1910s. Shortly after commissioning in early 1916, she participated in the Battle of Jutland of the First World War as part of the Grand Fleet.

Malaya spent the interwar period between the Mediterranean Fleet, Atlantic Fleet, and Home Fleet. She transported Ottoman Sultan Mehmed VI into exile and served during the 1936-1939 Arab revolt in Palestine. Apart from this, her interwar career was uneventful.

Admiral of the Fleet Sir Somerset Arthur Gough-Calthorpe GCB, GCMG, CVO, DL (23 December 1864 – 27 July 1937), sometimes known as Sir Somerset Calthorpe, was a Royal Navy officer and a member of the Gough-Calthorpe family. After serving as a junior officer during the Fourth Anglo-Ashanti War, he became naval attaché observing the actions of the Imperial Russian Navy during the Russo-Japanese War and then went on to command an armoured cruiser and then a battleship during the early years of the 20th century.

During the First World War Gough-Calthorpe initially served as commander of the 2nd Cruiser Squadron of the Grand Fleet, then became Second Sea Lord and after that became Admiral commanding the Coastguard and Reserves. In the closing years of the War he served as Commander-in-Chief of the Mediterranean Fleet, in which capacity he signed the Armistice of Mudros on behalf of all the Allies, by which the Ottoman Empire accepted defeat and ceased hostilities. The Occupation of Constantinople began with the Allied fleet entering Constantinople in November 1918 and it was Gough-Calthorpe's flagship, HMS Superb, that led the way.
