Least encouraging was the experience of the Serbian Third Army, which was defending the territory south of the Iverak Mountains. Here the Austrians developed a vigorous and persistent offensive, hoping to turn the Serbian left and thus capture the road to Valievo.
The attack on the positions at Jarebitze commenced at daybreak on August 16, 1914. Here the Serbians held good ground: rocky summits, but so limited in extent that there was room only for a few companies at a time. On the other hand the ground before them was broken up into hollows screened by growing corn. This enabled the Austrians to deploy their lines beyond the Serbian flanks unseen. They did execute just such a movement, and attempted to circle around toward the Serbian rear.
At the same time the Serbians here were attacked from in front by another hostile column which had come from across the plain on the south side of the Jadar valley, where hollows, sunken roads, and fields of corn again formed ample screening. However, in spite of all these movements, the Serbians were able to hold their own. The Austrian attacks were all beaten back. Their position might have been held indefinitely, but developments to the south were taking on a threatening form.
It will be remembered that an Austrian force had been reported approaching from the south, moving on Krupanie, and that it had seemed so insignificant that a small detachment of third reserve troops had been sent to hold it back. But this enemy force now developed into three mountain brigades.
Reenforcements of infantry and mountain artillery were hurried down to support the retaining force, but the Austrians were able to force their way on toward Zavlaka. Seeing Valievo thus threatened, the Serbians retired from their position at Jarebitze and took up a new position along a line from Marianovitche to Schumer, thus enabling them to face both the enemy columns. This retreat was fortunately not interfered with by the Austrians, though in executing it the Serbian artillery, which had been in position on the right bank of the Jadar, was obliged to pass along the Austrian front in single file, in order to gain the main road.
Early the next morning, August 17, 1914, the Serbians were in position and had extended their line to Soldatovitcha, whence the detachment from Krupanie had retired. Summing up the day's fighting, and considering it as a whole, it will be seen that the Austrians had pretty well held their own, except on their extreme left, where they had failed to get in touch with their forces in Shabatz.
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.
Unfortunately, at about that time the Third Army again called for assistance, and this hard-pressed division was compelled to send it. The result was that it was compelled to withdraw gradually to the heights of Kalem. The retirement was executed in good order, and the Austrians satisfied themselves with occupying Kugovitchi. Intrenching themselves in their new position, the Serbians awaited further attacks. Only an ineffectual artillery fire was maintained by the enemy. Meanwhile came the good news of the success of the Serbians along the Tzer ridges, so preparations were made for another advance on the following day, August 18, 1914.
As has already been stated, the extreme south wing of the Serbian front, the Third Army, had retreated the day before so that it could present a solid front against not only the forces opposing it, but also another column coming up from the south, whose advance had been inadequately covered by third reserve men. Here the Austrians attempted to pierce the Serbian line in the extreme south and come out at Oseshina. But though vastly outnumbered, the Serbians held their ground stoutly until late afternoon, when, as already shown, they were compelled to ask the division operating along Iverak for assistance. When this help came they were able to resume their defense.
Thus ended the second day of the general battle. On the whole the Austrians had suffered most, but the general situation was still somewhat in their favor. The Austrian center, along the Tzer ridges, had been pushed back. To retrieve this setback the logical course for the Austrian commander in chief was to curl his wings in around the Serbian flanks. That he appreciated this necessity was obvious, to judge from the furious onslaughts against the Serbian Third Army in the extreme south. But to weaken the Serbian center by these tactics it was also necessary to free the Austrians in Shabatz, or, at least, it was necessary that they should assume a strong offensive against the extreme right of the Serbians, and, if possible, flank them.
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
