But the Serbians anticipated the plans of the Austrians.  Additional reenforcements were sent to the extreme right with orders to spare no sacrifice that would keep the Austrians inclosed within their fortifications around Shabatz.

And true enough, next morning, August 18, 1914, shortly after the hot summer sun had risen over the eastern ridges, the Austrians emerged from Shabatz and attacked the Serbians.  The Austrian onslaught was furious, so furious that, step by step, the Serbians, in spite of their reenforcements, were driven back.  Fortunately toward evening the Austrian offensive began losing its strength, and that night the Serbians were able to intrench along a line from Leskovitz to Mihana.

This obliged the cavalry division, which had been cooperating with the Serbian center and was driving the Austrians toward Leshnitza, to retire along a line from Metkovitch to Brestovatz.  Naturally the advance of the Austrians from Shabatz was endangering its right flank.  Moreover, a reenforced column of Austrians also appeared before it.  But this opposing force did not press its advance.

Meanwhile, on the same day, August 18, 1914, the Austrians were reenforcing their position on the Tzer ridges.  They had also strongly fortified the height of Rashulatcha, which lay between the heights of Tzer and Iverak, whence they could direct an artillery fire to either field of activities.

But the difficulties which the Serbians operating along the Iverak ridges were meeting also hampered the Serbians who were attempting to sweep the Austrians back along the Tzer ridges.  If they advanced too far they would expose their flank to the Austrians over on Iverak.  As a general rule, it is always dangerous for any body of troops to advance any distance beyond the general line of the whole front, and this case was no exception.  However, though delayed, this division did advance.  Oxen were employed in dragging the heavy field pieces along the trails over the rocky ridges.

With savage yells the Serbian soldiers leaped over the rocks, up the jagged slopes of Kosaningrad.  Again they had fallen back on their favorite weapons, bayonets and hand bombs.  The Austrians put up a stout resistance, but finally their gray lines broke, then scattered down the slopes, followed by the pursuing Serbians.  Having gained possession of Kosaningrad Peak, the Serbian commander next turned his attention to Rashulatcha, which, in conjunction with the Serbians over on Iverak, could now be raked by a cross artillery fire.  He had previously left a reserve force behind at Troyan.  This he now ordered to reenforce his left, which had been advancing along the southern slopes of the Tzer range.  This force he now directed against the heights, but the movement was not vigorously followed up.
