In the following year Maximianus defeated the Germans near Treviri, and Diocletian himself marched against other tribes on the Rhætian frontier; the year after he defeated the Sarmatians on the lower Danube. In the same year, 289, peace was made between Carausius and the two emperors, Carausius being allowed to retain possession of Britain.
XLV. In the meantime, Labienus engages in a successful cavalry action among the Treviri; and, having killed several of them and of the Germans, who never refused their aid to any person against the Romans, he got their chiefs alive into his power, and, amongst them, Surus, an Aeduan, who was highly renowned both for his valour and birth, and was the only Aeduan that had continued in arms till that time.
Allured by this hope, the Germans were then making excursions to greater distances, and had advanced to the territories of the Eburones and the Condrusi, who are under the protection of the Treviri.
VII. While these things are being performed by Caesar, the Treviri, having drawn together large forces of infantry and of cavalry, were preparing to attack Labienus and the legion which was wintering in their territories, and were already not further distant from him than a journey of two days, when they learn that two legions had arrived by the order of Caesar.
II. Indutiomarus having been slain, as we have stated, the government was conferred upon his relatives by the Treviri. Having found some states willing to accede to their wishes, they enter into a compact with them by a mutual oath, and give hostages as a security for the money: they attach Ambiorix to them by an alliance and confederacy.
Having left a strong guard at the bridge on the side of the Treviri, lest any commotion should suddenly arise among them, he leads over the rest of the forces and the cavalry.
XI. He therefore sends T. Labienus, his lieutenant, with the cavalry to the Treviri, who are nearest to the river Rhine. He orders P. Crassus to proceed into Aquitania with twelve legionary cohorts and a great number of the cavalry, lest auxiliaries should be sent into Gaul by these states, and such great nations be united.
XXVI. About fifteen days after they had come into winter-quarters, the beginning of a sudden insurrection and revolt arose from Ambiorix and Cativolcus, who, though they had met with Sabinus and Cotta at the borders of their kingdom, and had conveyed corn into our winter-quarters, induced by the messages of Indutiomarus, one of the Treviri, excited their people, and after having suddenly assailed the soldiers, engaged in procuring wood, came with a large body to attack the camp.
Cneius Lentulus Gaetulicus says that he was born at Tibur; Pliny the younger, in the country of the Treviri, at a village called Ambiatinus, above Confluentes ; and he alleges, as a proof of it, that altars are there shown with this inscription: "For Agrippina's child-birth." Some verses which were published in his reign, intimate that he was born in the winter quarters of the legions,
The Remi, Lingones, and Treviri were absent from this meeting; the two former because they attached themselves to the alliance of Rome; the Treviri because they were very remote and were hard pressed by the Germans; which was also the reason of their being absent during the whole war, and their sending auxiliaries to neither party.
