And having been brought together when night was well advanced, all were embarked whom forty scouting boats[*](See note, p. 313.) (as many as were available at the time) would hold, and ordered to go down stream so quietly that they were even to keep their oars lifted for fear that the sound of the waters might arouse the savages; and while the enemy were watching our campfires, the soldiers
While this was being done with all haste, Hortarius, a king previously allied with us, not intending any disloyalty but being a friend also to his neighbours, invited all the kings, princes, and kinglets to a banquet and detained them until the third watch, prolonging the feasting after the native fashion. And as they were leaving the feast, it chanced that our men unexpectedly attacked them, but were in no way able to kill or take any of them, aided as they were by the darkness and their horses, which carried them off wherever panic haste drove them; they did, however, slay the lackeys or slaves, who followed their masters on foot, except such as the darkness of the hour saved from danger.
When word at last came of the crossing of the Romans, who then, as in former campaigns, expected to find rest from their labours wherever they should succeed in finding the enemy, the panic-striken kings and their peoples, who were watching with eager intentness and dreading the building of the bridge, shuddering with fear, took to their heels in all directions; and their unbridled anger now laid aside, they hastened to transport their kindred and their possessions to a greater distance. And at once every difficulty was removed, the bridge was built, and before the anxious nations expected it our soldiers appeared in the land of the savages, and were passing through the realms of Hortarius without doing any damage.
But when they reached the territories of kings that were still hostile, they burned and pillaged everything,
The kings were at once followed also by Vadomarius, whose abode was over against the Rauraci, and since he presented a letter of the emperor Constantius, in which he was strongly commended, he was received kindly (as was fitting), since he had long before been taken by Augustus under the protection of the Roman empire.
And Macrianus indeed, when admitted with his brother among the eagles and ensigns, was amazed at the variety and splendour of the arms and the forces, things which he saw then for the first time, and pleaded for his subjects. But Vadomarius, who was familiar with our affairs (since he lived near the frontier) did indeed admire the equipment of the splendid array, but remembered that he had often seen the like from early youth.
Finally, after long deliberation, by the unanimous consent of all, peace was indeed granted to Macrianus and Hariobaudus; but to Vadomarius, who had come to secure his own
But when they themselves also, after the burning of their harvests and homes and the capture or death of many men, sent envoys and made supplication as if they too had committed these sins against our people, they won peace on the same terms; and among these conditions it was especially stressed that they should give up all the prisoners whom they had taken in their frequent raids.
