It will be recalled that when Russky's army advanced, a portion of the Austrian Reserve Army, commanded by Archduke Joseph Ferdinand, was hurriedly withdrawn from the position it held in Poland on the left of the Vistula, across the rear of Dankl's army, to assist General von Auffenberg. This was referred to as an "advance," in a "communique" published by the Austrian General Staff on September 3, 1914. It is probable that at that very early date some German troops also were being brought up for the same purpose. Some of the Austrian reenforcements had been joined with Von Auffenberg's army and had shared in its reverses. Some had remained to screen Dankl on the right. After Von Auffenberg's army began to encounter difficulties and its progress was stopped, the gap between its left and Dankl's right and rear grew too large for safety, so that there was a hurrying of forces from the left bank of the Vistula to fill the gap. Later, as the Russian strength grew, an entirely new Austrian army was assembled, consisting, it seems, of portions of the Third or Reserve Army under Archduke Joseph Ferdinand, which was augmented by two corps withdrawn from the Serbian frontier, and also some German troops. The "Fourth" Army, under the command of the Archduke, was referred to thereafter in official announcements by Russia as the "Tomaszow Army." To strengthen Dankl's left, which lay upon the Vistula at Opolie, German troops from Breslau also were brought up. In the last part of August and the first part of September, 1914, there was considerable confused fighting between detached forces on both sides in the frontier country between Zamosc and Sokal. Both sides claimed successes. The Russians claimed that their wedge was driven through successfully to Tomaszow and that there a severe defeat was administered to the Austrians. From there the latter retired to the swampy land about Bilgoraj and upon Tarnograd. The tactics of the Russians had put a last barrier between the two principal sections of the Austrians. Interest thereafter centered in Dankl's First Army. Fighting on the Lublin-Kholm front, having been purely defensive on the part of the Russians, at first, had grown fiercer as days passed, until there was continuous battle along the entire line. When Von Auffenberg had been defeated and his right and rear threatened, the condition of the northern army seemed so critical that General Dankl decided to force the issue. He might fall back or break through the Russian defense. He decided to attempt to pierce the line between Lublin and Kholm. On September 2, 1914, the Tenth Austrian Army Corps led the assault against the weaker part of the Russian line and reached within eleven miles of Lublin. There it was halted, and so the Austrian offensive seems to have spent itself.
