Howdy DJV and welcome to the forum. Here is a link for more info I dug up. Perhaps you may see something here. BTW, what was your father's name?

328th Field Artillery Battalion

The 328th Field Artillery Battalion is one of the 3 artillery units that made up the artillery support of the 85th Custer Division. The 328th Field Artillery(or FA) Battalion trained at Camp Shelby, MS and entered combat in May 1944 with the Custer Division. They participated in capture of Rome, attack of the Gothic Line, heavy fighting in the Appenine Mountains, crossing of the Po River and drive to the Alps.

The 85th Division consisted of 328th, 329th, 403rd and 910th FA Battalions. A typical Battalion consisted of 3 batteries, each containing four 105mm howitzers and one battery of 155mm howitzers. Each battery was sighted in together and could fire at same targets simultaneously after initial ranging shot. In July of 1944, two additional guns were added to the battery. Later, a Tank Destroyer battalion, operating self-propelled artillery, became designated as Battery "D" of 328th FA Battalion.

Also, generally, one artillery battalion was assigned to one infantry regiment and one battery was assigned to a specific infantry battalion (or 4 infantry companies). Thus, 328th FA was assigned to support the 337th Infantry Regiment and Battery B was assigned to support 2nd Battalion of that Regiment. However, due to the fluidity of the battle command, this changed a lot as the groups rotated through reserve status.
