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
Mutina surrendered to Pompeius; and Brutus was,
notwithstanding the safe-conduct promised to him, subsequently
put to death by order of that general. Alba too was, after a long siege,
reduced by famine, and the leader there was likewise executed.
Lepidus, pressed on two sides by Catulus and Pompeius, fought another
engagement on the coast of Etruria in order merely to procure
the means of retreat, and then embarked at the port of Cosa for Sardinia
from which point he hoped to cut off the supplies of the capital,
and to obtain communication with the Spanish insurgents.
But the governor of the island opposed to him a vigorous resistance;
and he himself died, not long after his landing, of consumption (677),
whereupon the war in Sardinia came to an end. A part of his soldiers
dispersed; with the flower of the insurrectionary army
and with a well-filled chest the late praetor, Marcus Perpenna,
proceeded to Liguria, and thence to Spain to join the Sertorians.
