HMS Cornwall'\HMS Cornwall' was a Royal Navy 9000 ton armoured cruiser of the Monmouth-class, launched at Pembroke, Wales in 1902. On the outbreak of the First World War in 1914 she was despatched to West Africa to intercept German merchant shipping. She proceeded to the Falklands in the squadron commanded by Vice-Admiral Sturdee, and on 8 December 1914 engaged German light cruisers in the Battle of the Falkland Islands, sinking the Leipzig.
Returning to West Africa until June 1915 she was sent to support the Gallipoli campaign. The following October she went back to the East Indies and China Stations to protect Allied shipping from surface raiders. Returning to the UK in 1917 she was refitted and escorted convoys between Canada and the UK. She paid off early in 1919 and scrapped in 1920.
