Russia entered World War I with an army which was massive but badly armed. Russia suffered quick body blows from Germany and went on to one disaster after another. It lost 1,650,000 men killed, 3,850,000 wounded and 2,410,000 prisoners before the 1917 revolution which ousted the tsar and ended Russia's part in the war. Here reservists, accompanied by relatives, are called up in St. Petersburg as the army was assembled. #

Original caption: "Russian Troops in Flight. A remarkable photograph of a scene which followed the recent revolt of Russian troops on the Eastern front. The photo illustrates the first mad rush of the Slavic soldiers at a point of the line, where a cry was raises: 'The German cavalry have broken through.' With the raising of the cry the mad stampede started and not one of the runners paused for breath until he had put several miles between him and the firing line." #

Over 320,000 were recruited for service with the Allied Forces despite the fact that China was engrossed in her own domestic turmoil. #
