The squadron initially had no base. Admiral Tirpitz had visited the Chinese coast in 1896 and selected the existing harbour at Kiautschou as a likely site. German offers to buy the site were refused, but the deaths of two German missionaries on 1 November 1897 provided an excuse for a cruiser squadron led by Rear Admiral Otto von Diederich to land troops on 14 November1897. China was militarily weak: a 99 year lease on the port was granted in March 1899 and colonisation of the territory began. A naval base with a supporting, neighboring infrastructure was then built at the fishing village of Tsingtao (now Qingdao) to create the Ostasiatische Station (East Asia Station) of the Imperial Navy.[1]
The 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 Russianprotected cruiserZhemchug and the FrenchdestroyerMousquet, catching the Russian ship by surprise while in harbour. At Madras she destroyed oil storage facilities by shelling. The ship finally met its end on 9 November 1914 after a prolonged struggle with HMAS Sydney at the Battle of Cocos.
The four small gunboats Iltis, Jaguar, Tiger and Luchs of the East Asia Squadron that had been left at Tsingtao were scuttled by their crews just prior to the capture of the base by Japan in September 1914 during the Siege of Tsingtao.
