2. From this place he ordered all the booty and the prisoners to be brought to Metz, to be left there till his return. Then departing for Mayence, to lay down a bridge at that city and to seek the barbarians in their own territories, since he had left none of them in arms, he was at first met by great opposition on the part of his army; but addressing them with eloquence and persuasion he soon won them to his opinion. For their affection for him, becoming strengthened by repeated experience, induced them to follow one who shared in all their toils, and who, while never surrendering his authority, was still accustomed, as every one saw, to impose more labour on himself than on his men. They soon arrived at the appointed spot, and, crossing the river by a bridge they laid down, occupied the territory of the enemy.
3. The barbarians, amazed at the greatness of his enterprise, inasmuch as they had fancied they were situated in a position in which they could hardly be disturbed, were now led by the destruction of their countrymen to think anxiously of their own future fate, and accordingly, pretending to implore peace that they might escape from the violence of his first invasion, they sent ambassadors to him with a set message, offering a lasting treaty of agreement; but (though it is not known what design or change of circumstances altered their purpose) they immediately afterwards sent off some others with all speed, to threaten our troops with implacable war if they did not at once quit their territories.
4. And when this was known, the Cæsar, as soon as all was quiet, at the beginning of night embarked 800 men in some small swift boats, with the intention that they should row with all their strength up stream for some distance, and then land and destroy all they could find with fire and sword.
5. After he had made this arrangement, the barbarians were seen at daybreak on the tops of the mountains, on which our soldiers were led with speed to the higher ground; and when no enemy was found there (since the barbarians, divining their plan, immediately retreated to a distance), presently large volumes of smoke were seen, which indicated that our men had broken into the enemy's territory, and were laying it waste.
6. This event broke the spirit of the Germans, who, deserting the ambuscades which they had laid for our men in narrow defiles full of lurking-places, they fled across the river Maine to carry aid to their countrymen.
7. For, as is often the case in times of uncertainty and difficulty, they were panic-stricken by the incursion of our cavalry on the one side, and the sudden attacks of our infantry, conveyed in boats, on the other; and therefore, relying on their knowledge of the country, they sought safety in the rapidity of their flight; and, as their retreat left the motions of our troops free, we plundered the wealthy farms of their crops and their cattle, sparing no one. And having carried off a number of prisoners, we set fire to, and burnt to the ground all their houses, which in that district were built more carefully than usual, in the Roman fashion.
8. And when we had penetrated a distance of ten miles, till we came near a wood terrible from the denseness of its shade, our army halted for a while, and stayed its advance, having learnt from information given by a deserter that a number of enemies were concealed in some subterranean passages and caverns with many entrances in the neighbourhood, ready to sally forth when a favourable opportunity should appear.
9. Nevertheless our men presently ventured to advance in full confidence, and found the roads blockaded by oaks, ashes, and pines, of great size, cut down and laid together. And so they retreated with caution, perceiving that it was impossible to advance except by long and rugged defiles; though they could hardly restrain their indignation at being compelled to do so.
10. The weather too became very severe, so that they were enveloped in all kinds of toil and danger to no purpose (forasmuch as it was now past the autumnal equinox, and the snow, which had already fallen in those regions, covered the mountains and the plains), and so, instead of proceeding, Julian undertook a work worthy of being related.
11. He repaired with great expedition, while there was no one to hinder him, the fortress which Trajan had constructed in the territory of the Allemanni, and to which he had given his own name, and which had lately been attacked with great violence and almost destroyed. And he placed there a temporary garrison, and also some magazines, which he had collected from the barbarians.
