*The Great Retreat – The buildup of forces from the Central Powers on the eastern front was very effective at pushing the Russian’s back during the summer of 1915. Germans started their offensive in June of 1915 and gained ground in Poland through must of June and July of that year. On August 4th /5th German troops took Warsaw and Russian troops quickly retreated further east. This retreat caused Tsar Nicholas II to dismiss Grand Duke Nicholas Nikolaevich as leader of the war effort and to take control of the military directly.
