Sigild had surrounded the camp with a number of wooden towers placed on the old rampart, which had been strengthened. These towers, whose appearance is shown in [Fig. 6], were made of trunks of trees piled one upon another, and framed at their extremities. They projected from the rampart. At their summit was constructed a wooden floor surrounded by a parapet of wattling; and this floor was reached by means of a ladder placed inside the tower. The under story gave shelter to the men charged with the defence of the towers, and who watched from the top. If they perceived any suspicious movement without, it was their duty to give the alarm by blowing a horn. Sigild had fixed the number of men for each tower at twenty. Two of these twenty men remained day and night on the platform, the day and the night being each divided into four parts; there were eight men on duty during the day and eight during the night. Of the four remaining, the first was constituted chief of the tower; the second was intrusted with the stores, and the distribution of food and munitions; the third was to be at the disposal of the chief of the tower, to carry messages and seek for help in case of need; and the business of the fourth was to repair the injuries caused to the defences in the event of an attack.

As the circumvallation measured four thousand five hundred paces, and the towers were one hundred paces apart, there were forty-five towers, including the stronger and loftier ones placed on the two sides of the entrances. Nine hundred men sufficed to guard them. Sigild had taken the precaution of having a store of timber and branches brought within the inclosure of the Oppidum. By his care the wells had been deepened, and a trench dug outside the ramparts, towards the north. In addition to the flocks that habitually grazed within the camp, a great number of cattle had been brought by the fugitives to the plateau. But it would not have been possible to feed all these animals if stores of fodder had not been laid in beforehand. Accordingly, great stacks of grass had been placed along beside the rampart, thatched with reeds.

Between the towers the guarding of the ramparts was intrusted to a thousand men, put under the order of fifty-three chiefs; the two entrances were under the command of warriors of tried courage, and well known to Sigild.

This garrison, consisting of about two thousand men, had long been settled in the camp, and had partly executed the work of its fortification. As to the fugitives, they might have amounted to twelve thousand; and out of this number two thousand at least were able to fight, were provided with arms, and had been habituated to endurance.

In place of the original huts, which had fallen to decay, Sigild had formed a kind of halles, or vast sheds. There were eight of these sheds; one for every tribe. In front of each were disposed, at regular distances, circular fire-places, formed with flat stones, and intended for cooking. As soon as the sun appeared above the horizon a confused sound of voices succeeded to the silence which had gradually fallen upon the plateau. But Sigild had not lost time during the night. Orders had been given to his trusty followers; eight mounted chiefs, followed by armed men, went among the multitude of fugitives, and pointed out to each tribe the locality that had been assigned it. Whether through lassitude, or from a sense of danger, the multitude obeyed, and towards the middle of the day the camp had ceased to present the appearance of disorder it exhibited the evening before. Around the sheds, which were insufficient for such a number of families, might be seen men making huts with branches. The larger animals were fastened to stakes, and browsed on the grass which had not been too much trodden; the sheep were folded, and the women were preparing the day's repast; in every quarter the children were running about, and seemed to enjoy this new life. As to the warriors, they silently kept watch on the ramparts and the towers.

In the morning the valley was filled with a thick mist, and the hills were visible on either side above it; upon their ridges was no sign of the enemy, and from the white vapour which hid the valley, not a sound issued. Had the enemy withdrawn? Was it a false alarm?

From the camp the course of the river was scarcely distinguishable beneath the thick cloud of mist which covered it. Towards the end of the first quarter of the day Sigild sent out a detachment of a hundred men, with orders to explore the bridge and the banks of the river and rivulet. If no enemy appeared they were to follow the course of the latter and to reconnoitre towards the north; they were to avoid engaging with the enemy. Ten men were to remain upon the bridge to collect brushwood, and set fire to it the moment they saw the enemy in the valley. Gradually the fog dispersed, and at noon the sun shone out in all its splendour through the whole extent of the valley. Nothing broke the silence, the air was still, and in the distance, cattle that had been forgotten were seen quietly grazing. Many of the fugitives wished to leave the camp and return to their houses, with a view to remaining there, or to fetch articles which they had been unable to bring away. Sigild doubled the posts at the gates, with orders not to let any one go out. He went from one to another, trying to make the people understand that the enemy, far from withdrawing, was only waiting an occasion to seize the unwary who attempted to return to their homes. "They are in ambush," he urged; "they hope that you will relapse into security and will become their prey without a struggle; for though they covet your goods, they are still more anxious to get possession of your persons: they will carry you off to sell you, your wives and your children, as slaves among the nations beyond the mountains." Despite this warning, however, a great number were crowding towards the points of exit, and the armed men had hard work to keep the multitude back, when there arrived at the eastern entrance fifty of the warriors sent by Sigild to reconnoitre. They were covered with mud and sweat. When interrogated by the Brenn, they said that about three thousand paces from the camp, towards the north, among the woods, and although they were proceeding cautiously, they saw themselves all at once surrounded by the enemy: that many of them had been killed or captured; that they owed their escape only to their knowledge of the neighbourhood, and that they effected it by rushing into a narrow ravine filled with underwood and decayed trunks of trees, and leading down to the rivulet, not far from the camp. "Your chief is killed?" said the Brenn. "We do not know." "You left him behind you!" "We had orders to avoid any engagement." "You have not abandoned your arms?" "We have our arms." "Go and take rest." In an instant the entrances were clear, and the crowd returned in silence to its camping grounds.

Sigild then went to the northern end of the camp; he looked long through the depths of the forest; then he summoned to this front five hundred armed men from the tribes, besides those who were at their post; he stationed them behind the parapet, and ordered them to keep silence. He went into each of the towers raised on that side, and spoke in a low voice to each of the chiefs. Then all at once a shout arose from the southern side of the plateau. The Brenn mounted his horse and rode off hastily in that direction; but on his way he was told that the bridge was on fire, and that the ten warriors stationed there were coming in by the western gate.

"You have seen the enemy?" said Sigild, when the ten warriors made their appearance. "We have seen them: they were advancing in a strong body towards the bridge, endeavouring to screen themselves behind the reeds and willows." Then Sigild selected a hundred men from among his best warriors, and posted them on the slopes of the plateau outside the western gate, ordering them to pile up underwood and trunks of trees in the sunken road, to keep behind on the banks, and not use their bows and slings till they saw the enemy near the barricade; and if they attempted an assault on this point in a considerable body, to retire within and occupy the ramparts, helping those intrusted with their defence. In reality, however, the Brenn did not anticipate any serious attack on that side, which was difficult of approach. He thought the enemy would not attempt an assault with a river at their back, even should they succeed in crossing it. His attention was once more directed to the north. On this side, in fact, the camp is separated only by a slight hollow from the adjacent plateau, which widens and affords space for the gathering of a large number of troops, and a secure retreat in case of failure. He had also ascertained that the enemy already occupied the wide, forest-covered plateau.
