 The armoured cruiser was disabled by British shells and was sunk, but the rest of the German force escaped, with the German battlecruiser and the British battlecruiser badly damaged.On 15 April 1915, "V2", searching for the British submarine , which had torpedoed and damaged the "Sperrbrecher" (or auxiliary minesweeper) "Schwarzwald" on 14 April, dropped several depth charges on an oil slick south of the Amrum Bank thought to from a submarine.Further searches by minesweepers could not find any hint of the suspected submarine, and in fact, "E5" had already left the German Bight by the time "V2" carried out her attack.
