Zoom in a couple of clicks and you'll see Roth a little south and west of Mettendorf.This is just the general area where they fought.The 319th IR didn't take Roth until Feb 21, so somewhere within probably a mile or so radius of Roth is probably where he was wounded.
Yes, Purple Hearts were generally awarded in the hospital where the soldier was being treated, hence your paperwork.The paper refers to the 217th General Hospital, which at the time was in Paris.The APO 887 is the Army Post Office Number for the area.
You've already got alot of information.Since you have his discharge papers, there's probably no point in writing to the NPRC.Many of the WWII records were destroyed in a fire in 1973, so often all you'll get is a handwritten statement of service, which is what you have on the discharge papers anyway.
Go to the VA for medical records.Your next step is probably contacting the 80th Div. reunion organization, and finding more specifics about the action.As I said in an earlier post, you probably won't find out specifically how he was wounded, but you'll get a fair idea of what the 319th IR was doing that day.If you're lucky you can maybe get historical information down to the Company level. Write or call the National Archives Modern Military Records Section in College Park, MD and get the 80th Division After Action Report for February 1945.It should contain some good details regarding the actions on Feb. 20.
The book "The Last Offensive" by Charles MacDonald has a paragraph about the 319th IR's actions:
"The 319th Infantry meanwhile maneuvered against the pillboxes along the Our. Advancing along the west bank of the Gay Creek, the first stream line behind the river and the pillboxes, one battalion during the night of 18 February occupied high ground near Niedersgegen, nestled at the bottom of the creek valley, amd soon after daylight took the village itself. The next day, 20 February, the same battalion turned west to the Our, cutting off the Germans in a two and a half mile stretch of the West Wall."
