Between 1939 and 1945, close to 13 million men served in the German army - das Heer. The bulk of these men were infantrymen, who slogged their way, mostly on foot, from Finisterre to Moscow, Kirkenes to Tripoli. They swore unlimited obedience to Adolf Hitler and were ready to stake their lives for this oath: over 1.6 million men of das Heer were killed during the war and over 4.1 million were wounded.
