Deelite, you have quite a treasure there with the letters. I am willing to bet that he said all he could to your grandmother about his experience without running afoul of the censors. The AAR probably will not refer to the camp by any descriptive terms such as "concentration", "death" etc. Also, most of the main camps had satellite camps and it is not uncommon for soldiers to understand that had liberated "A" camp when it was actually "A-1" camp. Regardless, it was still a numbing experience for the men involved. You probably will have to obtain a listing of all camps and their satellite camps and then go piece by piece through the AAR, using a period map, to find the location. You might alos consider tracing the path of the 19th Corp, since the 2nd AD was under that command's control during the fight across Germany. I would like a copy of the 2nd AD AAR, if you are offering. If he was B Company, then he would have been in the 1st Battalion.
