On May 31, 1915, they began to roar, and before long the trenches were completely pulverized--the very trenches that thousands of Germans and Austrians had died in vain attempts to carry by assault. The Thirty-eighth Hungarian Honved Division were sent to finish the work of clearance and take possession of Stryj. The entire Russian line withdrew to the Dniester, step by step, ever fighting their favorite rear guard actions, killing and capturing thousands of their enemies. They retired behind the Dniester, but maintained their hold on any useful strategical position south of the river, so far as was possible without imperiling the continuity of their line. We must also consider two more Austro-German sectors in order to bring the combatants stationed there into line with the Germanic advance--the Uzsok Pass and the Bukowina-_cum_-Eastern Galicia sectors. In the former the army of Von Szurmay stood beside that of Von Linsingen opposite the Ninth Russian Army. Von Szurmay led his men out of the pass and advanced northward on May 12, after the fall of Sanok had forced the Russians away from their positions in the vicinity of it. Their line of retreat was threatened by the Austrian approach to Sambor. On May 16, 1915, Von Szurmay moved across the upper Stryj near Turka and passed along secondary roads in the direction of the oil districts of Schodnica, Drohobycz and Boryslav, arriving on May 16-17, 1915. Von Linsingen's troops had started their advance on the same day as those of Von Szurmay, when the Russians found Koziowa had to retire for the purpose of keeping in touch with their line: the same pressure that Sambor exerted on the Uzsok. Here again the Russians adopted rearguard tactics and considerable fighting occurred during their retreat to Stryj and Bolechow, both of which were eventually captured by Von Linsingen. In Eastern Galicia and the Bukowina matters had come almost to a standstill between Lechitsky and Von Pflanzer-Baltin about the middle of May, 1915. When the former had cut the latter's connection with the main line, the brigade of General von Blum and other adjoining German troops on the extreme right of Von Linsingen tried hard to relieve the pressure of Lechitsky on the Austrian forces. Not till after the fall of Przemysl was the connection restored, when the Russians had to fall back from Kalusz and Nadvorna; on June 9 they evacuated Obertzn, Horodenka, Kocman and Sniatyn. Lechitsky was also compelled to withdraw from the Bukowina between Zaleszczyki, Onut, and Czernowitz, where the Austrians were moving along the Dniester in the north, the Pruth in the south, and over the hills in the center against the village of Szubraniec. Here the Russians once more inflicted severe losses on the Austrians, but being in danger from a flanking movement by the Forty-second Croatian Infantry through the Dniester forests, they retired from the Bukowina on to Russian territory on June 12, 1915. * * * * *
