Did Germany and the Allies use pre-dreadnoughts in the early Dardanelles campaign?
Short answerYes; older battleships were suitable for bombardment work, although HMS Queen Elizabeth also joined the operation.
NotesPre-dreadnoughts no longer belonged in the front line against modern dreadnoughts, but their heavy guns remained useful against fixed coastal defenses. They were therefore serviceable for Dardanelles bombardment, although the Allies also committed the modern super-dreadnought HMS Queen Elizabeth.
