The small cavalry detachment that had been left behind as rear guard cut through the Austrian lines and rejoined the main forces on the Wisloka. The Austrians had been bombarding Tarno for months with their heaviest artillery, destroying parts of the cathedral and the famous old town hall in the process. On May 7 the Russians withdrew from the Pilzno district, and the Dunajec-Biala Russian front had ceased to exist. From the hour that the Austro-Germans had broken through the line at Ciezkovice, on May 2, 1915, the Russian retreat on the Wisloka had begun. Yielding to the terrible pressure the line had increasingly lost its shape as the various component parts fell back, though it gradually resumed the form of a front on the Wisloka banks, where most determined fighting continued for five days. The Russians lost much of their artillery; they had to reverse the customary military practice of an army in retreat. If the retreating army is well equipped with artillery and munitions, its guns cover the retreat and are sacrificed to save the men. During their retreat the Russians had often to sacrifice men in order to save their guns for a coming greater battle at some more important strategic point. Many prisoners fell to the Germanic armies; according to their own official reports they took 30,000 in the fighting of May 2-4, 1915. What the Austro-German side lost in that time was not made public. * * * * * CHAPTER XXX AUSTRO-GERMAN RECONQUEST OF WESTERN GALICIA
