6. German Wehrmacht (Operation Barbarossa, Early Campaign)
The German Wehrmacht’s initial phase of Operation Barbarossa in 1941 showcased the effectiveness of blitzkrieg tactics, enabling rapid advances through the Soviet Union’s snow-laden terrain. Utilizing coordinated assaults by infantry, tanks, and air support, German forces achieved significant territorial gains. However, as winter approached, the Wehrmacht faced unforeseen challenges. The onset of severe cold and heavy snowfall transformed roads into impassable quagmires, hindering supply lines and vehicle mobility. Additionally, the lack of winter clothing and equipment left soldiers vulnerable to frostbite and other cold-related injuries. These logistical and environmental difficulties significantly impeded the German advance, culminating in the eventual halt of operations near Moscow (theguardian.com).
