The correspondent of the New York "Times" on July 29, 1915, in a special cable summed up the situation in an announcement that the fate of Europe hung on the decision that Russia might make on the question: "Shall Russia settle down to a war of position in her vast fortifications around Warsaw, or shall she continue to barter space against time, withdrawing from the line of the Vistula and points on it of both strategic and political importance, in order to gain the time which Germany has already stored in the form of inexhaustible gun munitions?" The reply was the evacuation of Warsaw. The decisive blow to Russia's hopes came with the crossing of the Vistula about twenty miles north of Ivangorod on July 28, 1915, already noted. It showed that Warsaw was being rapidly surrounded. The Russian communique of the 30th of July told of the crossing over of the Teutons on both sides of the Radomka, a tributary of the Vistula, to the right bank of the Vistula on pontoons, and of attempts to throw bridges across the great rivers. Von Woyrsch's troops that had crossed over were irresistibly pursuing still farther east on the 30th, defeating troops hastily brought up to stop their advance. By August 1 two entire German army corps reached the right bank of the Vistula. Ivangorod, now threatened from all directions, could evidently not be held much longer. The fortress surrendered on August 4, 1915, after a violent bombardment of the outer forts had taken place, beginning on the first of the month. Austro-Hungarian troops under General von Koevess especially distinguished themselves in the attack on the west front. CHAPTER LX WARSAW FALLS The retreat from Warsaw began during the night of August 3 and 4, 1915. Already the city had been stripped as far as possible, to judge by reports from Petrograd, of metals, such as church bells and machinery that might possibly be of use to the Germans. A portion of the civilian population left the city. The Blonie line just to the west of the capital was given up under pressure from the Teutons on the 3d. While the retreat was taking place the Russians gave all possible support to their forces defending the Narew lines, so far as they still were maintained. Desperate charges were hurled by the Russians against the Germans moving forward all along the front Lowza-Ostrow-Wyszkow. The bravery of the Russians, especially in their counterattacks on both sides of the road from Rozan to Ostrow on the 4th of August, won the admiration of the Germans.
