Admiral Sir Ernest Charles Thomas Troubridge, (15 July 1862 – 28 January 1926) was an officer of the Royal Navy who served during the First World War.
Troubridge was born into a family with substantial military connections, with several of his forebears being distinguished naval officers.
He too embarked on a career in the navy, rising through the ranks during the late Victorian period, and commanding ships in the Mediterranean.
He spent some time immediately before the outbreak of the First World War as a staff officer and assisted in the drawing up of strategic plans to be adopted in the event of war, though these were later rejected.
He returned to seagoing service just prior to the outbreak of war, and commanded a cruiser squadron in the Mediterranean with the rank of rear-admiral.
Here his promising career was blighted by the events surrounding the pursuit of two German warships, SMS Goeben and SMS Breslau.
Despite being outclassed by the German warships, Troubridge intended to engage them, but was convinced otherwise by his flag captain and allowed them to escape to Constantinople.
He and his commanding officer were heavily criticised for their failure to intercept the German ships, particularly when it subsequently appeared that they became influential in the Turkish decision to enter the war.
Troubridge was court-martialled and although he was acquitted, his reputation had been damaged.
Troubridge never had another seagoing command, but did command naval detachments and flotillas on the Danube during the Balkan campaigns, winning the respect of Serbian Crown Prince Alexander.
After the war he served on the Danube Commission and was promoted to admiral, but remained out of favour with the Admiralty.
He spent several years as president of the commission, retiring in 1924 and dying in 1926.
He had married twice; his second wife, the sculptor Margot Elena Gertrude Taylor, left him to begin a lesbian relationship with the writer Marguerite Radclyffe-Hall.
