late but to return, nothing for the Treverian canton but to submit; its government reverted to the head of the Roman party Cingetorix, the son-in-law of Indutiomarus.  After these expeditions of Caesar against the Menapii and of Labienus against the Treveri the whole Roman army was again united in the territory of the latter.  With the view of rendering the Germans disinclined to come back, Caesar once more crossed the Rhine, in order if possible to strike an emphatic blow against the troublesome neighbours; but, as the Chatti, faithful to their tried tactics, assembled not on their western boundary, but far in the interior, apparently at the Harz mountains, for the defence of the land, he immediately turned back and contented himself with leaving behind a garrison at the passage of the Rhine.

Retaliatory Expedition against the Eburones

Accounts had thus been settled with all the tribes that took part in the rising; the Eburones alone were passed over but not forgotten.  Since Caesar had met with the disaster of Aduatuca, he had worn mourning and had sworn that he would only lay it aside when he should have avenged his soldiers, who had not fallen in honourable war, but had been treacherously murdered.  Helpless and passive the Eburones sat in their huts and looked on as the neighbouring cantons one after another submitted to the Romans, till the Roman cavalry from the Treverian territory advanced through the Ardennes into their land.  So little were they prepared for the attack, that the cavalry had almost seized the king Ambiorix in his house; with great difficulty, while his attendants sacrificed themselves on his behalf, he escaped into the neighbouring thicket.  Ten Roman legions soon followed the cavalry.  At the same time a summons was issued to the surrounding tribes to hunt the outlawed Eburones and pillage their land in concert with the Roman soldiers; not a few complied with the call, including even an audacious band of Sugambrian horsemen from the other side of the Rhine, who for that matter treated the Romans no better than the Eburones, and had almost by a daring coup de main surprised the Roman camp at Aduatuca.  The fate of the Eburones was dreadful.  However they might hide themselves in forests and morasses, there were more hunters than game.  Many put themselves to death like the gray-haired prince Catuvolcus; only a few saved life and liberty, but among these few was the man whom the Romans sought above all to seize, the prince Ambiorix; with but four horsemen he escaped over the Rhine.  This execution against the canton which had transgressed above all the rest was followed in the other districts by processes of high treason against individuals.  The season for clemency was past.  At the bidding of the Roman proconsul the eminent Carnutic knight Acco was beheaded by Roman lictors (701) and the rule of the -fasces- was thus formally inaugurated.  Opposition was silent; tranquillity everywhere prevailed.  Caesar went as he was wont towards the end of the year (701) over the Alps, that through the winter he might observe more closely the daily-increasing complications in the capital.
