Another difficult problem which confronted both the Russians in their retreat and the Germans in their advance was that of transportation, especially in the region between the Vistula and the Bug Rivers. Not only is the number of railroads in that territory very small, but neither side had available a large enough number of railroad cars to transport the large number of men and vast quantities of equipment involved. This necessitated the creation of new means of transportation. According to a correspondent of the Hungarian newspaper "Az Est" the problem was solved by the Austro-German armies in a remarkable way. In the first place the number of horses before each wagon was increased. Where formerly two horses had been used, four were employed now, and where four used to be considered sufficient the number was increased to six. This resulted in an unending line of giant transports drawn by teams of four and six horses like they had never been seen before.
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.
