After the attack on the Archduke Ferdinand of  Austria Hungary, Germans became hostile to Russia. Russia attacked Germany. The truth is that Russia had to give up because of the less infrastructural and road transport facilities were lacking which made Russia difficult to deploy its soldiers in major fronts.
