In 13 parts a blow by blow account which must have been written by a Japanese authour and translated sometime in the 1930s it includes some incredible detail on forces actions fortifications etc around Tsingtao in 1914..... A complete detailed operational history of the Siege till its fall.
Your welcome Roger unfortunatly the 14? or so maps showing positions and locations dont appear to be with it, but im sure could be sourced from else where.. practically all of the forces involved and their actions seem to be recorded in detail down to the officers names.... a fairly leisurely campaign, very civilised the Japanese allowed all non coms who wished too to leave the area...
