Six legions were formed of the men newly called out; of these two remained in Rome and two in Etruria, and only two embarked at Brundisium for Macedonia, led by the consul Publius Sulpicius Galba.

After the Perusine war he joined Antony at Brundisium in the spring of 40, and acted as his spokesman at the conference which led to the momentous treaty of peace.

The Roman fleet conveyed a division of the army from Brundisium to Epirus; Oricum was recaptured from the king, a garrison was thrown into Apollonia, and the Macedonian camp was stormed.
