Pre-war manoeuvres. Members of the 3rd Naval Battalion move a heavy machine gun through the rough terrain around Tsingtau. 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.
