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
Now it was enough. When Caesar was informed by the tribunes
who had fled to his camp entreating protection as to the reception
which his proposals had met with in the capital, he called together

and unfolded before them the state of things.
It was not merely
the man of genius versed in the knowledge and skilled in the control
of men's hearts, whose brilliant eloquence shone forth and glowed
in this agitating crisis of his own and the world's destiny;
nor merely the generous commander-in-chief and the victorious general,
addressing soldiers, who had been called by himself to arms
and for eight years had followed his banners with daily-increasing
enthusiasm.
