Map of defense layout, First US Army HQ, Spa

[Simon Trew]

This is an interesting map, dated 31 October 1944, of the defense layout for  FUSA's HQ at Spa (Belgium).  The town and surrounding area appear to have been divided into sub-sectors (Red, Green, Blue and White.  There was a Main Line of Resistance fairly close to the town, and what I assume are checkpoints (numbered red dots), some only them on high ground with fields of observation.  Units involved appear to have been many and varied. Hope some people find this interesting.
