Dear Richard,
Thanks a lot for your bibliography, which will prove of utmost help to me.
Well, I've tried to find of copy of Monroe Mason's book through Addall Used Books and there was one for... $750.00!!! I'm not certain I'm going to buy this one...
As for the rest, I'll try to find cheaper copies.
What you can tell me is: is it worth buying some of these titles, knowing that I'm only looking for elements about the involvement of the regiments in the Vosges/Alsace sector (where I live)? I mean, do these volumes contain real new elements (maps? photos?) about that topic?
Best regards
Eric
