the controversy that arose from the assassination of the Austrian Crown Prince at Sarajevo (in Bosnia, Austria) on June 28, 1914. Serbia mobilized, and it was generally believed that this action was due to Serbia's knowledge that Russia was secretly mobilizing. By about July 10, 1914, Germany believed herself satisfied that Russia was actually mobilizing, and she also began secretly to do so. France became suspicious of German military activity, and by the end of the third week and the beginning of the fourth week in July a general, but unadmitted, military preparation was in progress. Actual and admitted mobilization is more or less arbitrarily placed as of August 1, 1914, which date is now generally regarded as the opening of the Great War.
In any consideration of Russian mobilization it will be remembered that Russia had three armies, not one, to mobilize, i.e., the armies of European Russia, of the Asiatic Russia, and of the Caucasus. It is also to be remembered that, unlike the German system in which every man has a definite place in a particular corps, the Russian system holds its reserves as reserves solely, and organizes them after they have been gathered together. Slow mobilization is therefore an evil not to be avoided. For this reason one must expect to find Russian mobilization occurring, not on the frontier, but at a point sufficiently far therefrom to be safe from hostile attack during the period of disorganization.
The line Bialystok-Brest-Litovsk was the main field selected, because of its central location between the Austro-German frontiers, and more particularly because it was well covered from attack by the intrenched fortress and camp of Warsaw. The troops and reserves from Little Russia, especially from the Kiev district, were readily available on lines converging to the Austrian city of Lemberg in Galicia, and, it was estimated, could take the front in ten days. From this district five army corps are raised. From the Odessa district to the south two more army corps could be counted upon, and these could reach the scene of operations in twelve or thirteen days. In actual speed of mobilization the Austrian army was ready first, but the Russian army protected and covered the slow mobilization and concentration of its forces by a dense curtain of cavalry masses, for which task the rapidly mobilized Cossack cavalry was especially well fitted. These cavalry engagements—for the Russians were met by the Hungarian cavalry—effectually screened the actual gathering of the armies, and led Austria into the error of supposing Russia to be quite unready. But, although Austria had been the first to begin actual mobilization, her strategic railways on the frontier were so poor that it was not until August 10, 1914, that she was ready to advance, and even then that single line of railroad running from the Bug to the Vistula was deficient in rolling stock. Austrian military organization was excellent, Hungarian railroad organization was utterly inadequate to cope with the sudden requirements of modern warfare.
The Austrian army advanced on Russia in force, expecting the success of the German armies to the east. From the plans as they developed, and particularly from railroad orders given to the lines crossing Germany, it was expected that before Russia could be mobilized sufficiently to do more than give a temporary check to the Austrian army, several German army corps could be released from the western front and sent to the Russian border to take the burden of Russian invasion away from Austria. But the resistance of Belgium against Von Kluck's armies, the resistance of France against the armies of the crown prince, and the resistance of England to all naval action, prevented any release of the German armies, and the mobilization orders for the transference of German troops from the western theatre to the eastern theatre of war during the first few weeks of the struggle proved to be unavailing, for the men could not be spared. Slowly but heavily the mobilization of Russian forces continued. Lacking strategic railroads, lacking the motor-lorry system of England, the heavy-footed but untiring Russian infantry marched the scores and hundreds of miles from their homes to the front. The Russian dirigibles and aeroplanes were more than a match for the Austrian aircraft, and kept them back from flying over the country to determine the number of forces opposing. Then the action of the Russian "steam roller" began, and with more men marching in every day, unwearied despite their long travel, the steam roller gathered force. But, in one regard, Russia had miscalculated. She had never contemplated the terrific wastage of ammunition that is required for modern artillery duels, gun conflicts that are necessary before troops can advance, and in the first few weeks of the war her ammunition was all shot away. Without ammunition the steam roller could not continue, and the advance of the Russians upon Austrian territory was first halted and then driven back. Here, again, then, was a campaign successfully begun because of a better mobilization of men than was expected, and lost because of a lack of mobilization of supplies.
A great deal has been said of the slowness of Russian mobilization, and much of it is undoubtedly true. But little has been said about the steadiness of Russian mobilization. The Russian officer, almost always a noble, and belonging to what is probably the most polished and most cultured class in Europe, an aristocrat to his finger tips, possesses the power of commanding men, and understands his Slav soldiers. He knows that no army in the world can begin to compare with the Russian for enduring hardship, and that no troops in the world can sustain so large a proportion of loss and still advance. Forced marches that would kill English troops can be handled by a Russian army without great fatigue. The principal note in the gathering of the czar's armies was that day by day, week by week, from every corner of the empire, men went to the front. It was not the sudden concentration of Germany, it was not the eager formation of France, it was not the heroic sturdiness of Belgium, it was not the accustomedness to active service of the British regulars, it was a gradual transition of an idealistic people from contemplation into action.
German-Belgian Frontier, Strategic Railroads on.
To the Russian, more than to any other of the peoples engaged in the war, mobilization spells advance, advance in a thousand ways. Germany, France, and England were practically unchanged in temperament and viewpoint by the mere processes of mobilization, but old Russia became new Russia almost within a month. War is the greatest unifier of racial dissension in the world, and when the first three months of war were over, the German Empire, the British Empire, the Republic of France and her colonies, and above all, the Russian Empire, were welded by the grim forces of necessity into homogeneous units. Moreover, mobilization and the conditions of war bring into high relief the powers and the characters of the several nations, and as the story of the war is told, its developments portray the changing appreciations of the national combatants for each other, and of the neutral nations for all.
