Please note that Mommsen uses the AUC chronology (Ab Urbe Condita), i.e. from the founding of the City of Rome. You can use this reference table to have the B.C. dates
The attack came so unexpectedly, that the very men
absent from the camp could not be recalled and were cut off
by the enemy; otherwise the immediate danger was not great,
as there was no lack of provisions, and the assault, which the Eburones
attempted, recoiled powerless from the Roman intrenchments.
But king Ambiorix informed the Roman commander that all the Roman camps
in Gaul were similarly assailed on the same day, and that the Romans
would undoubtedly be lost if the several corps did not quickly set out
and effect a junction; that Sabinus had the more reason to make haste,
as the Germans too from beyond the Rhine were already advancing
against him; that he himself out of friendship for the Romans
would promise them a free retreat as far as the nearest
Roman camp, only two days' march distant.
