The Allied airborne and amphibious landings on D-Day opened up the long-awaited Second Front against Nazi Germany, but after overcoming the German coastal defenses at Utah and "Bloody Omaha," the US Army found itself having to contest every hedgerow and street in a nightmarish battle of attrition. It was the humble infantrymen of both sides who would play a vital role in taking and holding key objectives. Battles across Europe tested both sides to the limit, from the close-quarters warfare around Cherbourg in June 1944 to the struggle for the Scharnhorst Line in October and the brutal cold-weather fighting in the Ardennes that December. Featuring full-color artwork, specially drawn maps, and archive photographs, this study offers key insights into the tactics, leadership, and combat performance of the US and German infantrymen pitched into three pivotal actions at the height of World War II.
