Robert Whalen reports that after four years of battle, 2,037,000 German soldiers had died; 4,300,000 were wounded; and 974,977 reported missing or wounded. Total casualties: 7,311,977. 

The boxcars that transported Jews to their deaths in the Holocaust were the same boxcars that transported German soldiers to their deaths in the First World War.
