Admiral Sir Ernest Charles Thomas Troubridge, was an officer of the Royal Navy who served during the First World War.

The pursuit of Goeben and Breslau was a naval action that occurred in the Mediterranean Sea at the outbreak of the First World War when elements of the British Mediterranean Fleet attempted to intercept the German Mittelmeerdivision consisting of the battlecruiser SMS Goeben and the light cruiser SMS Breslau. The German ships evaded the British fleet and passed through the Dardanelles to reach Constantinople, where they were eventually handed over to the Ottoman Empire. Renamed Yavuz Sultan Selim and Midilli, the former Goeben and Breslau were ordered by their German commander to attack Russian positions, in doing so bringing the Ottoman Empire into the war on the side of the Central Powers.
