She entered service for Royal in the Atlantic Fleet and at the outbreak of world war one she was stationed in Rosyth as part of 8th Desrtoyer Flotilla. 5.September 1914 she got the doubtful honor of being the first warship in history to be sunk by a self-propelled torpedo. The German uboat U-21 under command of Kapitänleutnant Otto Hersing spotted the cruiser outside St Abbs Head. She was hit in the forward ammunition storage and sank within a few minutes in the deep together with 259 men. The wreck rest today on a depth of 54 to 68 meter northeast of St Abbs Head.
