When we think of the German Army we think of the Blitzkrieg years, 1939–41, during which Panzers pushed deep into enemy territory and forced huge encirclement battles that annihilated the enemy’s strength in Poland, France, the Balkans and the Soviet Union. With their Auftragstaktik and cutting-edge weaponry, they epitomised incisive modern war. However, there was an elephant in the room, and in spite of their superb battlefield leadership, their brilliant victories, their technical prowess, their mighty Tigers and Panthers, they lost because of it. It wasn’t, as the German generals argued postwar, the Soviet hordes that swamped them. It wasn’t the industrial capabilities of the United States. It wasn’t the control exerted by a dictator increasingly removed from the real world.

All these points helped swing the war in the Allies’ favour but they weren’t the main reason why the German Wehrmacht lost. The elephant in the room was logistics. It’s easy to point out how well the Germans achieved their Blitzkrieg successes, but the war didn’t end in 1941.

In the end, at the critical moments in the war, their logistics failed them
