To add a bit more information, already provided in the replies:
My father was the first sergeant of Battery B, 938th Field Artillery Battalion (155 mm).The battalion was most associated with the 3rd Infantry Division, 36th Infantry Division, and the 45th Infantry Division (providing general support) throughout the war.In today's Army, the battalion would be categorized as corps artillery (supporting those three infantry divisions).
The battalion was at Anzio; the invasion of southern France; the campaign up the Rhone River valley; and the battle at Colmar, France.It crossed the Rhine River near Ludwigshaven, Germany.His battery ended the war at Fuessen, Germany in Bavaria.Fuessen lies at the foot of the mountain, on which Neuswanstein (that Disney-like castle seen in so many photographs of Germany) sits.Battery B, 938th FA fired its last round of the war from there at German troops located just over the German-Austrian border.
The 938th's battalion commander was Lieutenent Colonel Milton B. Coburn between 1942 and 1945.Coburnretired as a major general in June 1970.
As already noted, Anzio was rough.And yes, James Arness (Marshal Matt Dillon in Gunsmoke) was there.As a machine gunner with the 3rd Infantry Division, he was wounded at Anzio.Some of the wounded infantry declined going to the field hospital in the rear at Anzio.They believed they were safer remaining in the line.German artillery shelling of the rear area (which was very small) was intense.After the breakout from Anzio, the battalion participated in the liberation of Rome on 5 June 1944.The invasion at Normandy occurred the following day, so Rome did not receive much press.
The 938th FA Bn landed at Sainte Maxim on 14 or 15 August 1944, accompanying the 45th Infantry Division (Delta Force -- not related to today's organization).Sainte Maxim is directly across the bay from Saint Tropez, also an objective for this force.The 3rd Infantry (Alpha Force) landed simultaneously on beaches a bit to the west of Saint Tropez.The 36th Infantry (Camel Force) landed to east at Saint Raphael.German resistance was light, which after Anzio, was welcome.
In final note, the 45th Infantry Division liberated the concentration camp at Dachau.Troops in the immediate vicinity were required by their commanders to view the camp.The 938th was among them.It was there, a day after the camp was closed and bodies still remained unburied, that our soldiers learned why they had fought this war.
