"Emden" disrupted trade throughout the Indian Ocean, intercepting 29 ships and sinking those belonging to Britain or its allies. At the Battle of Penang she sank the Russian protected cruiser and the French destroyer "Mousquet", catching the Russian ship by surprise while in harbour. At Madras she destroyed oil-storage facilities through shelling. The ship finally met its end on 9 November 1914 after a prolonged struggle with HMAS "Sydney" at the Battle of Cocos.
