The 1917 Battle of Passchendaele, the Germans were well-entrenched, with mutually-supporting pillboxes which the initial bombardment had not destroyed. After three months of fierce fighting the Canadian Corps took Passchendaele on 6 November 1917, ending the battle, but in the meantime the Allied Powers had sustained almost half a million casualties and the Germans just over a quarter of a million. The Allies had captured a mere five miles (8 km) of new front at a cost of 140,000 lives, a ratio of roughly 2 inches, or about 5 cm, gained per dead soldier. This is a trailer for the upcoming movie about this battle.
