The same day that brought the report of this Russian retreat on the south brought the news that in the adjoining sector to the west of the Upper Vistula the army of General von Woyrsch had met resistance from the Russians behind the Ilzanka after the Russian defeat on July 13, 1915, that, however, Silesian Landwehr on the 18th had captured the Russian defenses at Ciepilovo by storm, and that the Russian line at Kasonow and Barenow was beginning to yield. The army of General von Gallwitz had now taken up positions along the whole Narew line from southwest of Ostrolenka to Novo Georgievsk. The Russians, however, as already indicated, were still holding fortified places and bridgeheads on the right bank of the river. In this sector the number of prisoners taken by the Germans had risen to 101 officers and 28,760 men. In the sector next adjoining, passing onward around the enveloping lines, that lying between the Pissa and the Szkwa, the Russians likewise had retreated until they stood directly on the Narew. Here the Slavs had been favored by forests and swampy land which made pursuit difficult. At the extreme left end of the German line a magnificent success had been achieved in the occupation of Tukkum and Windau. This capture brought the Germans to within fifty miles of Riga, seat of the governor general of the Baltic provinces. They were, however, destined not to make any substantial progress in the direction of that city for many months to come. Blow fell upon blow. The question "Can Warsaw be held?" began to receive doubtful answers in the allied capitals. The colossal coordinate movement of the Teutonic forces in these July days had received so little check from the Russian resistance that the British press had begun to discount the fall of the Polish capital. Shortness of ammunition and artillery was ascribed as the cause of Russia's failure to make a successful stand against the onrushing Teutons. On July 20, 1915, Berlin announced the capture of those fortifications of Ostrolenka lying on the northwest bank of the Narew River. This was one or the strong places designed to protect the Warsaw-Grodno-Petrograd railway. The threatened fall was highly significant. To the south of the Vistula the Teuton troops had advanced to the Blonie-Grojec lines. Blonie is some seventeen miles west of Warsaw and Grojec twenty-six miles south of the city. Farther eastward and to the south troops of the army of General von Woyrsch had completely turned the enemy out of the Ilzanka positions, having repulsed the counterattacks of the Russian reserves which had been quickly brought up, and captured more than 5,000 prisoners. Von Woyrsch's cavalry had now reached the railway line from Radom to the great fortress of Ivangorod, the objective point of this army, and Radom itself had been seized. * * * * * CHAPTER XLVII BEGINNING OF THE END
