The Eighth HMS Severn
In 1914 the RN purchased three River Amazon monitors built by Vickers for Brazil. These, renamed Mersey, Humber and Severn, were specialist shore-bombardment ships. After supporting the Army in Belgium, Severn and Mersey were towed to German East Africa where they destroyed the Imperial German cruiser SMS Königsberg, at the Battle of the Rufiji Delta. After a long refit in Alexandria she served on the lower Danube in 1919. She was sold in 1921 and scrapped in 1923.
