Kapitanleutnant Gunther Pluschow and his Rumpler Taube aeroplane represented the only viable source of airpower available to the defenders. Accordingly the besiegers devoted great efforts to downing both man and machine. They were unsuccessful, and Pluschow managed both to escape from Tsingtau before the capitulation and make his way back to Germany. A NEW BOOK has shed light on Britain???s little known dirty war in the Far East during WW1 as they allied with Japan to take German territories in China. Rare images show Japanese forces as they led siege to Tsingtau in order to wrest it from German control. Other pictures show the German and Chinese naval personnel who attempted to defend Tsingtau and Kapitanleutnant Gunther Pluschow and his Rumpler Taube aeroplane represented the only viable source of airpower available to the defenders. The images are included in a new book, The Siege of Tsingtau, by Charles Stephenson and published by Pen and Sword.
