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 Tarnow 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 XLII AUSTRO-GERMAN RECONQUEST OF WESTERN GALICIA By the time the retreating Russians had reached the Wisloka they had to some extent recovered from the first shock of surprise, and were better able to attempt a determined stand against the overwhelming onrush of the Austro-Germanic troops. Ivanoff hurriedly sent reenforcements for Dmitrieff and Ewarts which included the Caucasian Corps of General Irmanoff from the Bzura front. The heavy German guns belched forth with terrible effect, and the Russians could not reply at the same weight or distance. Bayonets against artillery means giving odds away, but the attempt was made. With a savage fury that seems to belong only to Slavs and Mohammedans--fatalists--the Russians hurled themselves against the powerful batteries and got to close quarters with the enemy. For nearly twenty minutes a wild, surging sea of clashing steel--bayonets, swords, lances and Circassian daggers--wielded by fiery mountaineers and steady, cool, well-disciplined Teutons, roared and flowed around the big guns, which towered over the lashing waves like islands in a stormy ocean. A railway collision would seem mild compared with the impact of 18,000 desperate armed men against a much greater number of equally desperate and equally brave, highly-trained fighters. But machinery, numbers and skillful tactics will overcome mere physical courage. The Russian avalanche was thrown back with terrific slaughter; the Caucasian Corps alone lost over 10,000 men, for which, it is estimated, they killed and wounded quite as many.
