Photograph, World War Two, North West Europe (1944-1945), 1944. The 105 mm M2A1 (M101A1) howitzer was the standard American light field howitzer of the war. The US 3rd Army was commanded by Lieutenant General George Patton. His attack across the Saar River was underway when the Germans launched their Ardennes Offensive further north. Operations on the Saar were thus scaled down as the 3rd Army shifted troops north to counter the German attack.
