Since the September days of 1914, when for the first time interminable columns of Russian war prisoners poured into Germany after the Battle of Tannenberg, it seemed as if the stream would never end but that as soon as one army was defeated and routed another would take its place. The supply of soldiers which the gigantic Empire placed at the disposal of the Czar seemed inexhaustible; new victims were always at hand for the holocaust of war. How long could Germany hold out in this competition?

And what then? According to human standards a Russian victory over Germany might be delayed but it would have to come in the long run.
