It was an ideal place for a crossing. Farther up, at the neck of the isthmus, was an old river bed, where the Save had once cut a straight channel. This was now full of stagnant water, while between it and the ford the ground was covered with thick timber. The stagnant water, while not very deep, afforded somewhat the same protection that a wire entanglement would, and the woods served as a screen to the advance guard of the Serbians stationed there to guard the crossing. Not far distant, farther up in Austrian territory, was a small town, Obrez.

After the Serbian army had crossed safely, it set to work clearing the timber away, it being no longer necessary to screen themselves from view, and a strong line of trenches was thrown across the neck of the isthmus, thus effectually protecting the ford for retreat, should that be necessary.

At this moment two regiments of infantry and a battery of artillery of the enemy appeared and attempted to oppose the further advance of the Serbians, but when the Serbian guns began shelling the forest opposite, this force fled in the direction of Obrez. Then the left of the Serbian force worked its way around toward the town itself and, after firing some dozens of shells, entered it and drove the Austrians still farther on.

The cavalry division now came up to secure possession of the town. The two divisions then set to work to intrench themselves. Meanwhile the Serbian right, advancing toward the northeast, encountered another force of the enemy, consisting of one regiment and two batteries, and, after a short skirmish, drove it back and occupied the two villages, Kupinovo and Progar. Thus the Serbian operations in this section fared well.

But at another point, on the extreme left, at Mitrovitza, they did not encounter such good fortune. The division operating here was to occupy and fortify Mitrovitza and with it a bridge, after which it was to advance and worry the enemy's flank. The actual point chosen for the construction of the bridge was a customs station at Jasenova Grada, between Mitrovitza and Jarak.

The column here had arrived at the river bank at midnight of September 5, 1914, and at early dawn had begun building the pontoon bridge. Meanwhile a steady artillery and rifle fire was kept up, sweeping the opposite bank, to keep back the enemy. The Serbian commander of this force had received instructions to the effect that as soon as he had moved his troops across safely, he was to send two regiments forward: one to the right, the other to the left, and the whole line was to advance and cover the territory between Mangjeloskabara and Shashinshi, the object being to push back any movement of the Austrians from Jarak.

As at Novoselo, an advance guard crossed in barges before the bridge had been thrown across. Immediately a heavy fire began from the enemy, hidden in the opposite forest. Many of the Serbians threw themselves into the river, and either swam or waded the rest of their way across.

Finally three barge loads had effected a crossing. While waiting for the rest to follow, sixty of the Serbians threw themselves over against the Austrians and, by their very boldness, drove them out of their trenches and took twenty prisoners.

Some delay in the building of the bridge followed, but more barge loads of soldiers were sent across, and the fighting with the Austrians was pushed vigorously. But meanwhile the enemy was also being reenforced, more rapidly for not having a river behind him. By evening the Serbians, who had crossed, found themselves tremendously outnumbered and fighting on the defensive. At that time, one of the Serbian Regiments, which had advanced as far as Shashinshi, found itself isolated, with both flanks exposed.

After two hours of stubborn fighting the regiment managed to draw back to the river bank, carrying with them a mass of wounded comrades, hoping there to find the support of the main body of their army. But the pontoon bridge had not yet been completed. Of the 400 yards across the river, only twenty remained unbridged. Seeing their advantage, the pursuing Austrians redoubled their attack furiously. The Serbian regiment, with half its men down, and only 60 feet of water between itself and the main corps, turned, with its back to the river, and fought back with equal fury.
