After the defeat of the Austrians at Belikamen on August 16, 1914, the cavalry division was reenforced by some infantry and artillery, then sent on the delicate mission of driving a wedge in between the Austrians in Shabatz and those along the Drina. Spreading out across the Matchva plain, its left wing up against the slopes of the Tzer Mountains, and its right wing within reach of Shabatz, it advanced as far as Dublje in the north. At the same time it was able to assist the column advancing along the Tzer ridges by playing its artillery on the Austrian position in the mountains at Troyan. Throughout all the fighting this cavalry division rendered notable service by its dismounted action. On the morning of August 17, 1914, the extreme right of the Serbian front now turned toward Shabatz. Though only half the number of the forces they were proceeding to engage, they continued onward. But on closer approach it became apparent that they could do nothing more than hold the Austrians inside the town. So well and so thoroughly had the Austrians fortified themselves that it was hopeless for so small a force to attempt an attack. Thus this section of the Serbian front settled down to wait for reenforcements. The center and left of the Second Army now prepared to advance along the Tzer and Iverak ridges. The Austrians in this section, who had suffered so severely the day before at Belikamen, were now concentrated around Troyan, the most easterly and the second highest peak of the chain. At dawn on August 17, 1914, the Serbians located the Austrians. Immediately they began a heavy artillery fire on this position, then proceeded to infantry attack. Two regiments hurled themselves up the slopes, and with bayonets and hand bombs drove the Austrians back. After that no further progress was possible that day, the Serbians having to wait for their artillery to come up. The Austrians now began intrenching themselves on the heights of Kosaningrad, the loftiest portion of the Tzer range. Along the Iverak ridges the Austrians made a determined advance. The situation of the Serbian troops in this section, the left wing of the Second Army, was extremely dangerous, for their left flank was becoming exposed by the continued retreat of the Third Army. The only hopeful aspect of their situation was that the Austrians were also having their left flank exposed by the retreat of the Austrians along the Tzer ridges. Evidently the opposing forces realized this fact, for they made a fierce attempt to drive back the Serbians opposing them, so that their danger from the north might be lessened. Half an hour later they were severely repulsed. But heavy reenforcements came up to the Austrians just then, and again they attacked, this time more successfully. By noon, August 17, 1914, the Austrians had extended their line over to the Serbian right wing.
