The work of these horses was greatly lightened by field railways. So quickly were these built that they seemed to grow right out of the ground. In some places industrial railways of this nature, already in existence, were utilized. Both steam and horsepower were used on these railways. Valleys were bridged over; gradients were reduced by every available means. At regular distances pleasant little block houses were to be found, which served as stations and guardhouses. The condition of the roads did not permit the use of motor trucks to any great extent, but wherever there was even a thread of possibility for motor trucks to get through they were promptly called upon to assume a leading part as a means of transportation. The immensity of the problem may well be understood by the fact that approximately two thousand automobiles of all kinds were employed by the German army of the Bug River.

All of this could be moved quickly. Everything that was necessary to make repairs was carried along. Supplies were heaped on motor trucks, and the officers in charge of supplies and equipment lived in automobiles which had been fitted up like rooms. The supply and equipment departments had their own electric-lighting system and their separate wireless. This vast establishment could be mobilized in twenty-four hours, and its completeness, swiftness, efficiency, and punctuality were not only a triumph of modern industry, but were among the chief contributing causes for the Austro-German success in overpowering obstacles and difficulties, and for the fact that throughout the entire campaign in Russian Poland the troops never suffered lack of provisions and munitions.

The Russian retreat brought untold misery to the civil population of those parts of Russia which were affected by it. Especially true was this of those sections in which the Russian authorities decreed that the civil population had to become participants in the retreat and leave their homes and goods to the mercy of the invaders. The terrible suffering and misery resulting from these conditions will, perhaps, become more vivid from the following details taken from some Russian newspapers which will give an idea of the conditions: "In Moscow all railroad stations are overcrowded with refugees. Most of these are unable to leave the freight cars in which they had arrived because the tortures of hunger and thirst which they had to suffer during their trip had been too much for them. Thousands upon thousands of these unfortunate beings had been struck down by sickness, and as far as the capacity of the Moscow hospitals allowed had been cared for, while still other thousands had to be satisfied with accommodations in the open squares and streets of the city, while others were removed farther east in order to reduce the overcrowded conditions of the city. Every day some ten thousand refugees were sent east by way of Smolensk, Orel, and Tula. Among these were many thousands of German colonists who had formerly been residents of Cholm and Volhynia, but had been removed from there by order of the Russian Government previous to the Russian retreat. The fate of all these hundreds of thousands of refugees by the time winter will have arrived will be horrible. What, for instance, will happen to about thirty thousand farmers from Galicia who were removed by force and now are located in a concentration camp on the River Slucz with nothing over their heads except the sky?"

From all parts of the Russian Empire involved in the German advance, streams of these unfortunate victims of war were continuously flowing toward the east. One of the chief reasons for the extensive misery which they had to suffer was the fact that the Russian organization, which even in times of peace does not work any too well, broke down completely under this unexpected and unparalleled demand on its resources. In spite of the fact that the larger number of these refugees were driven east by the special and express command of the Russian authorities, the latter had made no preparations to take care of them nor did they seem to show much worry concerning their fate. Even some of the high Government officials pointed out, to the responsible Government departments that, as long as the Government had driven these unfortunate human beings away from their own homesteads without, in most cases, giving them time to gather in even their most necessary belongings, it had become the Government's duty to provide for them elsewhere in some fashion. If one considers that most of these people were without any resources whatsoever, and that the housing and feeding of such vast masses demanded the expenditure of large sums of money, which apparently were not available, it will easily be understood that all these men, women, and children of all ages and conditions suffered not only untold inconveniences, but actually the pangs of hunger and thirst, which in a great many instances resulted in the outbreak of epidemics and in the decimation of whole camps.

How a civilian observer was struck by some of the conditions in Poland may be gleaned from a description in one of the German monthly magazines rendered by an artist who accompanied one of the German armies on its invasion of Poland: "Of course the first thing one learns to know is the horrible condition of roads in Russia.... One of the other main difficulties is the lack of cleanliness which results in so many epidemics among the population. These two conditions presented serious problems to the invading army; for, of course, it became necessary to remove the difficulties arising from them as much as possible....

"The water supply also is of the worst on the eastern front, and when I wandered in the great summer heat through the trenches or drove by the hour with wagon and horse through the sandy wastes of Poland, I could not help but think of the many occasions when the fighting armies, in spite of all fatigue and hardships, had to go without drinking water of any kind whatsoever...."

One of the greatest successes which the Germans gained in the summer of 1915 was the taking of the fortress of Kovno. Indeed it was the fall of this Russian bulwark as much as anything else that precipitated most of the Russian losses after the fall of Warsaw. Considering the importance of Kovno the following report of a special correspondent of the "Berliner Tageblatt," who was present during its bombardment, will be of interest. He says:

"The bombardment had reached a strength which made one believe that he was present at a concert in the lower regions. Guns of every variety and caliber, up to the largest, had been concentrated here and attempted to outroar each other. In unceasing activity the batteries spit their devastating sheaths of fire against the Russian forts and against the fortified positions which had been thrown up by the Russians between the forts and which had been supplied by them with very strong artillery. The latter did its best to keep up with the efforts of the besieging army. Day by day the Russian guns began firing against the German lines almost as soon as the German lines had opened their fire and the combination swelled the noise to a terrible height.

"Exactly at seven o'clock in the evening the German guns paused for a while in order to permit their infantry to advance. This was an almost daily occurrence and day by day the German lines drew nearer to the Russian forts.

"Hardly had the fire of the German guns stopped when a furious crackling of rifle fire would begin. The German lines had left their trenches and were advancing against the Russian position from which they received heavy fire. Machine guns, too, joined the uproar. It was impossible to follow the infantry attack in detail, but its success could be gleaned from the fact that the German gun fire, which gradually was taken up again, had to be advanced in the direction of the fortress."
