We have mentioned that German troops were moving on Senkova, southeast of Gorlice, by night. During the last two days of April the Bavarians captured the Russian position in the Senkova valley. A further move was made here during the night of May 1-2, 1915, preparatory to dislodging the Russians from the ground they still held. At seven o'clock in the morning the big howitzers started to "prepare" that ground. By ten o'clock it was deemed that every living thing had perished, when the "fire curtain" was drawn behind the Russian position. Infantry were then thrown forward--some Bavarian regiments. To their intense astonishment they were received with a most murderous fire from Russian rifles, and machine guns. The first attack failed and many were killed, few getting beyond the wire entanglements. Cautiously other troops advanced to the battered Russian trenches cut off from the rear by the artillery screen behind. Yet here again they met with strenuous resistance in the Zamczysko group of hills. The Austrian artillery shelled the heights, and the Bavarians finally took possession. The Tenth Austrian Army Corps had meanwhile conquered the Magora of Malastow and the majority of the heights in the Ostra Gora group. On Sunday, May 2, 1915, the Austro-German armies pierced the Dunajec-Biala line in several places, and by nightfall the Russians were retreating to their last hope--the line of the Wisloka. The operations round Gorlice on that day resulted in breaking the Russian defenses to a depth of over two miles on a front of ten or eleven miles. Mr. Stanley Washburn wrote from the battle field at the time: "The Germans had shot their last bolt, a bolt forged from every resource in men and munitions that they could muster after months of preparation." Of the Russian army he said, "it was outclassed in everything except bravery, and neither the German nor any other army can claim superiority in that respect." With the center literally cut away, the keystone of the Russian line had been pulled out, and nothing remained but to retire. Ten miles north of Ciezkovice lies the triangle formed by the confluence of the Dunajec and Biala rivers and the Zakliczyn-Gromnik road. Within this triangle, commanding the banks of both rivers up to the Cracow-Tarnow line, the Russians held the three hills marked 402, 419, and 269 which figures express their height in meters.
