But the Austrian fire became heavier and heavier; a blast of steel pellets and shells swept through the cornfields and the plum orchards, tearing through the streets of the village and crumpling up the houses. The breastworks of the small Serbian detachment were literally the center of a continuous explosion of shells.
When a full tenth of their number lay dead or disabled, the Serbians began retiring across the cornfields and up the slopes leading to the heights behind Losnitza. There, on higher ground, which offered more effective shelter, they made a determined stand and continued their fire on the Austrian masses.
Having crossed the river, the Austrians threw up defensive breastworks and dug elaborate trenches, thus fortifying their crossing. Next they built a pontoon bridge, and then the main Austrian army poured across; a whole army corps and two divisions of a second.
Meanwhile, on the same day, August 12, 1914, a similar event was happening at Shabatz, on the Save, where that river takes a sharp southward turn and then swings up again before joining the Danube at Belgrade. Here the country is a level plain, really the southern limit of the great plain which stretches up to the Danube, past Belgrade and so into Hungary. Here, too, the Austrians screened themselves behind an island in the river, then hurled their forces across, driving the feeble detachment of Third Reserve Serbian troops back across the plain up into the hills lying to the southeast of Shabatz. Then the advance guard of the Austrian Fourth Army occupied the town, strongly fortified it and built a pontoon bridge across the river from their railroad terminus at Klenak.
Further passages of a similar nature were forced that day, August 12, 1914, at other points by smaller forces; one at Zvornik and another at Liubovia. In addition the Austrians also threw bridges across the river at Amajlia and Branjevo. Thus it will be seen that the invasion covered a front of considerably over a hundred miles and that six strong columns of the enemy had crossed, all of which naturally converged on Valievo. For Valievo was the terminus of a small, single track railroad which joined the main line at Mladenovatz. Thus the Austrians would have a convenient side door open into the heart of Serbia which was, of course, their main objective. To this Belgrade was merely incidental. With this line of transport and communication in Austrian hands, Belgrade would fall of itself.
From Losnitza, where the main column of Austrians crossed the Drina to Valievo, runs the River Jadar, along a level valley, which narrows as it nears Valievo. On the left-hand side of the Jadar Valley rise the southern slopes of the Tzer Mountains, covered with cornfields, prune orchards, with here and there a stretch of thick timber. Continuing southward, slightly to the eastward, up the Jadar Valley another range rises, slightly smaller than the Tzer Mountains, forming a smaller valley which branches off eastward. Along this runs the River Leshnitza, parallel with the Jadar until it makes an independent junction with the Drina. Still farther up the valley the foothills of the Iverak ridges are lost in a series of fairly important summits which closely flank the Jadar River.
To the south of the Jadar River the valley stretches into a rolling plain, which rises abruptly into the giant Guchevo Mountains. It is this range, converging with the Tzer and Iverak Mountains toward Valievo, and forming the plain of the Jadar Valley, which was presently to become the center of the first great battle between the Serbians and Austrians.
A military movement against Valievo, therefore, demanded complete possession of these two ridges, which overlooked the line of march. This the Austrians knew well enough, even before the first of their troops had crossed the Drina. As is well known, the best maps, not only of Serbia but of all the Balkan countries, have been made by Austrian engineers. There was probably not a spur, not a fissure, certainly not a trail, of these mountains that had not been carefully surveyed and measured by engineers of the Austrian staff.
The Austrians knew the country they were invading quite as well as did the native Serbians. All through it may be said that it was not through want of accurate knowledge that the Austrians finally met disaster. Rather was it because they misjudged the relative values of their facts. And one of their first mistakes was in overestimating the effects of the two Balkan Wars on the efficiency of the Serbian army. First of all, as was obvious from the leisureliness with which they proceeded to occupy the two mountain chains in question, that they vastly misjudged the capacity of the Serbian troops to make rapid movements. Even as the first shots were being fired across the Drina at Losnitza, the Serbian forces were on the move, westward. Two army corps were at once rushed toward the Valley of the Jadar; part of a third was sent to block the advance of the Austrians from Shabatz. Meanwhile the Austrians took their time. For two days they busied themselves fortifying the bridge at Losnitza.
CHAPTER XLIX
THE GREAT BATTLES BEGIN
On August 14, 1914, began the first battle of the Serbian campaign. The Austrians proceeded to storm the heights from which the small outpost detachments had all the time been bombarding them with its old-fashioned guns. The Serbians, though few in number, made a desperate resistance. It was their business to hold back the enemy as long as possible, even until the reenforcements should arrive.
Early in the morning of August 14, 1914, the Austrians advanced in a great mass, then charged up the hillsides toward the Serbian position. The Serbians waited until they were well up the steep slopes and the rush of the enemy had subsided to a more toilsome climb. Then they sent down volley after volley from every available weapon.
The Austrian soldiers, who had until then never experienced anything more warlike than field maneuvers, lost their nerves; the first line broke and ran at the first fire. However, that was likely to happen to any troops under fire for the first time. Down in the plain they formed again, and again they swept up the slopes. This time they did not turn at the first volley. On they came, with fixed bayonets. And presently the first line reached the top of the heights, and the fighting was hand-to-hand. For a moment the Serbians, overwhelmed by numbers, were on the point of fleeing. But these same men had been through many a hand-to-hand encounter with both Turks and Bulgars; that experience stood them in good stead. And again they swept back the attacking masses of Austria-Hungary.
By evening, August 14, 1914, the Austrians had not yet taken the heights. But the Serbians, most of them middle-aged and old men, had spent their vitality. As the dark night lowered over the scene, they fell back, until, at Jarebitze, they met the first advance guards of the oncoming Serbian main army. And here they halted, and the united forces proceeded to dig a trench on a ten-mile front, extending from north to south, through the town and clear across the Jadar Valley. Nor did the Austrians then attempt to follow up this first success. Thus the Serbians were allowed to intrench themselves unmolested until, next day, August 15, 1914, they were joined by the balance of their forces.
Now, by studying the map, it will be seen at a glance that it was only the Tzer Mountains which separated the Austrian column crossing the Drina at Losnitza and the column which had crossed the Save and had occupied Shabatz. Should the Austrians from over the Drina get possession of the Tzer ridges, they would thus effect a junction with the forces in Shabatz, and so form a line that would cut off a large portion of northwestern Serbia. Aside from that, they would have a solid front. But should the Serbians possess themselves of the Tzer ridges first, then they would have driven a wedge in between their two main forces. This would make it difficult for either to advance, for then they would be exposing a flank to the enemy, who would also have a great advantage in position. Moreover, the Serbians would be in a position to turn immediately toward either of the Austrians' columns, whichever might need most attention.
Meanwhile, the Serbian cavalry had made a reconnaissance toward Shabatz. They immediately sent back reports of overwhelming forces occupying the town. It was out of the question to make any attack there for the present.
It was now learned, for the first time, that another of the enemy's columns had crossed the Drina far down in the south, and was marching on Krupanie, just below the Guchevo Mountains and on the way to the upper part of the Jadar Valley. However, as the first report seemed to indicate that this was only a minor force, a small force of third reserve men was detached to hold this force back and prevent its entrance into the main
