Greetings, Kathleen Jacobs !
Your dad's company was in 16th Infantry Regiment,
1st Infantry Division, which I assume he joined as a replacement.
Since you only mention possible service in Germany, I will limit this to that period, meaning that he would probably have been credited with two campaigns:
Rhineland, 15 Sep 44 / 11 May 45
Central Europe, 22 Mar 45 / 11 May 45.
Mind you, though, 1st ID campaigned in North Africa, Sicily, Normandy (D-Day), and Ardennes-Alsace (Bulge), in
addition to the two above.
His Separation Papers will record his campaigns and awards, and unless he was wounded prior to the Bulge, he was probably there also.
Actually, the 16th IR led the division onto Omaha Beach on D-Day.
The division crossed the Meuse River at Liege, Belgium,
9 Sep 44, and reached the German border.
It assaulted Aachen, Germany, 12 Sep 44;
an attempt to encircle the town met stiff resistence, with
16th IR forced to halt at the West Wall, 15 sep 44;
16th IR held defensive positions near Eilendorf, against strong German attacks.
Aachen finally fell to the 1st ID, 21 Oct 44.
Operating under First Army, the division spearheaded the offensive to secure the Roer River crossings east of Aachen, 16 Nov 44;
15 days later, it had moved only four miles;
16th IR was attached to V Corps, 5 Dec 44;
1st ID was sent to the Malmedy sector, about 16 Dec 44,
in response to the German Ardennes-Alsace counteroffensive.
Having turned back the Germans in the Ardennes, the division was next involved in the assault on the West Wall, 28 Jan 45, attacking through Buchholz Forest.
16th IR attacked Kreuanau, 25 Feb 45, and crossed the Neffel River, 1 Mar 45;
The division captured Bonn, 9 Mar 45, thus ending all German resistence west of the Rhine River.
It moved to the Czechoslovakian border, 30 Apr 45, and participated in limited action up until the German surrender, 11 May 45.
Location at war's end, 15 Aug 45:
1st ID, Ansbach, Germany.
16th IR, Bamberg,Germany.
Stephen E. Ambrose mentions the 16th IR at least twice in his excellentbook, CITIZEN SOLDIERS.
I hope that this information is of benefit to you and to your family.
