Auxiliary units were set up WW2 in case of German invasion, they would of been the British resistance. This was one of their hideouts located in Park Wood Hellingly, close to the Hospital. Visited with Monk and Jackal.
Where abouts in Park Wood was this? You've got the car park up by where the Hospital used to be (which is now a vast housing estate) and two tracks that lead out in to the woods. One right, one left.
