With the end of the Dardanelles Campaign in January 1916, during which "Lord Nelson" had suffered no casualties, British naval forces in the area were reorganized and "Lord Nelson" became flagship of the Eastern Mediterranean Squadron, which was redesignated the Aegean Squadron in August 1917; under either name, the squadron was dispersed throughout the area to protect Allied-held islands, support the British Army at Salonika, and guard against any attempted breakout from the Dardanelles by the German battlecruiser and light cruiser . "Lord Nelson" spent the remainder of the war based at Salonika and Mudros, alternating between the two bases with her sister ship ; the ship was based mostly at Salonika, with "Agamemnon" mostly at Mudros.
