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
But, though Perseus stood almost alone, he was no contemptible
antagonist. His army numbered 43,000 men; of these 21,000 were
phalangites, and 4000 Macedonian and Thracian cavalry; the rest were
chiefly mercenaries. The whole force of the Romans in Greece amounted
to between 30,000 and 40,000 Italian troops, besides more than 10,000
men belonging to Numidian, Ligurian, Greek, Cretan, and especially
Pergamene contingents.
To these was added the fleet, which numbered
only 40 decked vessels, as there was no fleet of the enemy to oppose
it--Perseus, who had been prohibited from building ships of war by the
treaty with Rome, was only now erecting docks at Thessalonica--but it
had on board 10,000 troops, as it was destined chiefly to co-operate
in sieges. The fleet was commanded by Gaius Lucretius, the land army
by the consul Publius Licinius Crassus.
