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
Tidings successively arrived, that Flaccus, in
order not to be crushed by Sulla, had marched past him onward to
Asia (668); that Fimbria had set him aside and installed himself
in his room (beg. of 669); that Sulla had concluded peace with
Mithradates (669-670).
Hitherto Sulla had been silent so far as
the authorities ruling in the capital were concerned. Now a letter
from him reached the senate, in which he reported the termination
of the war and announced his return to Italy; he stated that he
would respect the rights conferred on the new burgesses, and that,
while penal measures were inevitable, they would light not on the
masses, but on the authors of the mischief.
This announcement
frightened Cinna out of his inaction: while he had hitherto taken
no step against Sulla except the placing some men under arms and
collecting a number of vessels in the Adriatic, he now resolved to
cross in all haste to Greece.
