Conclusion
From this brief outline may be seen how tremendous and important a role was played by Russia in the world conflict. Summing up the general facts cited above, we arrive at the following definite conclusions:
1.) Russia's role in the World War was bound to be very serious and important for this reason alone, that the participation of a nation numbering 180 million souls could not fail to be significant in itself, and was therefore bound to exercise a tremendous influence upon the outcome of the World War.
2.) Accordingly, Russia's role became apparent even at the very beginning of the War, in the important aid she rendered in frustrating the initial and most dangerous plan of the Germans, by her early offensive in aid of the Allies. Russia, having diverted against herself the entire Austrian army and part of the German, at the time of the battle on the Marne, through her offensive in East Prussia and Galicia, deprived the enemy of the opportunity to realize the fundamental idea of Moltke's plan to fling "all forces into France." The enemy, having contrary to his plan moved on France with only a part of his forces, inevitably suffered defeat. This cooperation on the part of Russia was of tremendous significance, for the Germans based their plan on the idea that they would at first have to deal only with France alone, on one front only, whereas Russia compelled them at once to start the War on two fronts, both with Russia and France. This made the initial German war plan useless because strategy says plainly: "Errors in the strategic deploying of forces in the beginning of a war have a decisive influence and cannot be rectified until the war is over." From this rule of strategy it is plain that Russia's operations in the beginning of the war at the outset condemned Germany to lose the war.
3.) At the following attempt of the enemy to find a decision in France, to break through to Calais, at Ypres, Russia, by the blows she delivered in Galicia, at Warsaw and in East Prussia, contributed to the early termination of this second offensive in France, so dangerous to England, and compelled the Germans for more than a year to abstain from their main operations on the main decisive front of the War—in France.
4.) In 1915 Russia, having shouldered alone the whole burden of the struggle against Germany, Austria and Turkey, although forced to abandon Poland, still gave the Allies the opportunity to prepare throughout a whole year for the coming German offensive at Verdun. At the same time, having compelled the Germans during 1915 to spend all their fresh formations and reserves on the Russian front, Russia thereby deprived the Germans of the reserves they needed for Verdun and their other operations in France.
5.) In 1916 Russia, thanks to the Brusilov offensive, saved Italy at that critical moment when the Austrians, through their successful offensive from Tyrol in the rear of the Italians, threatened to cut off a considerable portion of the Italian Army, at the same time menacing Venice. Together with this, Russia by this offensive greatly facilitated the operations of the Allies on the Somme, and was instrumental in the final clearing of the Verdun forts.
6.) In 1916 Russia took upon herself the blows of Mackensen's and Falkenhayn's armies which had invaded Roumania, stopped the further advance of the Germans, and undertook the defense of a considerable stretch of the Roumanian front.
