An East German Major appeared and asked if he could use the facilities for his men.
His unit were a recently formed tank unit of the East German Volkspolizei (there is no East German army at this point).
He said that although they had no money they could provide goods that would more than adequately provide compensation for the services that they used. A deal was done and the East Germans visited on a few occasions.
However the local British military intelligence (in the shape of one Captain Captain Parr and some redcaps) were sniffing around looking for the Major.
In the end Captain Parr's redcaps broke in while the Major was in bed with a girl and attempted to shoot him (according to the girl) and he returned fire seriously injuring the two redcaps. He then made good his escape via the Tunnels, much to Captain Parr's annoyance.
