Many histories written by professional historians discuss the Battle of the Bulge; however, none of them incorporate the growing field of environmental history as a lens of analysis. This paper aims to address that hole in the scholarship by evaluating the impact that environmental factors exerted on the American army's ability to fight in and around Bastogne and St. Vith, Belgium during the first week of the battle. Had it not been for the environmental factors and the Americans' ability to make better use of the natural and manmade conditions than the Germans, the Allies would not have been able to achieve eventual victory. In the historiography of the battle, weather conditions are usually referenced only as the setting in which the fighting occurred. This paper goes further than simply using the environment and climate as a stage set. By looking at the way environmental conditions impacted strategic, operational, and tactical issues, a new perspective is opened up. The role that these environmental factors played is emphasized and shows that they had a greater effect on the outcome than scholars have previously credited. This paper uses first person accounts from participants, from the command level to the soldier in his foxhole, as well as unit histories, oral histories, and the vast amount of secondary sources to focus on and synthesize the effects that the environment had. Without exploiting the environmental factors that existed in the Ardennes, the American army would not have been able to hold off the German offensive.
