While initially there were two "Taube" aircraft assigned to Imperial German units stationed at Qingdao, China, only one was available at the start of the war due to an accident. The Rumpler Taube piloted by Lieutenant Gunther Plüschow had to face the attacking Japanese, who had with them a total of eight aircraft. On 2 October 1914, Plüschow's Taube attacked the Japanese warships blockading Tsingtao with two small bombs, but failed to score any hits. On 7 November 1914, shortly before the fall of Qingdao, Plüschow was ordered to fly top secret documents to Shanghai, but was forced to make an emergency landing at Lianyungang in Jiangsu, where he was interned by a local Chinese force. Plüschow was rescued by local Chinese civilians under the direction of an American missionary, and successfully reached his destination at Shanghai with his top secret documents, after giving the engine to one of the Chinese civilians who rescued him.
