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
Thus overawed, the majority decreed what was commanded--
that Caesar should at a definite and not distant day give up
Transalpine Gaul to Lucius Domitius Ahenobarbus, and Cisalpine Gaul
to Marcus Servilius Nonianus, and should dismiss his army,
failing which he should be esteemed a traitor.
When the tribunes
of Caesar's party made use of their right of veto against this resolution,
not only were they, as they at least asserted, threatened
in the senate-house itself by the swords of Pompeian soldiers,
and forced, in order to save their lives, to flee in slaves'
clothing from the capital; but the now sufficiently overawed senate
treated their formally quite constitutional interference
as an attempt at revolution, declared the country in danger,
and in the usual forms called the whole burgesses to take up arms,
and all magistrates faithful to the constitution to place themselves
at the head of the armed (7 Jan. 705).
