Germany had not planned on the need to hold out for long and upon entering the war had a stockpile of nitrates for making gunpowder sufficient for six months and no more. Only the later discovery of a method for fixing nitrogen out of the air enabled her war effort to continue. The French, gambling on a quick finish, risked no troops on what would have been a difficult defense of the Lorraine iron basin but allowed the Germans to take it on the theory that they would regain it with victory. As a result they lost 80 per cent of their iron ore for the duration and almost lost the war.
