The Augustan Empire 43 BC

Then there were three weeks of inaction. The first battle had done nothing to ease the triumviral problems of supply, and Antony was forced to detach a whole legion to march to Greece for provisions. But Brutus was under pressure from his own army to fight again; he was a less respected general than Cassius, and after the first battle he feared desertions; and he also soon found his own line of supplies from the sea threatened, for Antony and Octavian occupied new positions in the south. He felt forced to accept a second battle (23 October). His own wing may again have won some success, but eventually all his lines broke. The carnage was very great; and Brutus too took his own life. With him died the republican cause. Several of the surviving nobles also killed themselves, some were executed, others obtained pardon; a few fled to Murcus, Ahenobarbus, or Sextus Pompeius. Most of the troops came over to the triumvirs.[9]

Antony had long been known as a military man, but until now his record was not especially lustrous. His wing had played little part at Pharsalus, he had been absent from most of Caesar's other battles, and the outcome at Mutina had been shameful. All that was now erased. Octavian had given little to this victory; he had indeed been absent from the first battle — hiding in the marsh, and not even his friends could deny it.¹⁴ Before the fighting the forces had appeared equally matched: it was Antony's operations that forced the battles, his valour that won the day. He took the glory and the prestige. Now and for years to come, the world saw Antony as the victor of Philippi.

iii. the east, 42-40 b.c.

Antony's strength was reflected in the new division of responsibility and power. His task would be the organization of the East; he was also to retain Further Gaul, and take Narbonensis from Lepidus; he would lose only the Cisalpina, which was to become part of Italy. Italy itself was nominally left out of the reckoning, but Octavian was to be the man on the spot, with the arduous and unpopular task of settling the veterans in the Italian cities. He was also to carry on the war against Sextus Pompeius; he would retain Sardinia; and he too was to gain at Lepidus' expense, taking from him both provinces of Spain. Lepidus himself would be allowed only Africa; and there was some doubt even about that.¹⁵ Already, clearly, he was falling behind his colleagues. Antony was also to keep the greater part of the legions. A large number of the troops in the East had served their time, and were to be demobilized; the rest, including those who had just come over from Brutus and Cassius, were to be re-formed into eleven legions. Antony was to take six of these, Octavian five; he was also to lend Antony a further two. The position concerning the western legions is more obscure, but there too Antony's marshals seem to have controlled about as many legions as Octavian.[10]Antony promised that Calenus would transfer to Octavian two legions in Italy to compensate for the two he was now borrowing: but such promises readily foundered. The legions stayed with Calenus.

In Antony's lifetime two generals had successfully invaded Italy from their provinces, Sulla from the East and Caesar from Gaul. Both Gaul and the East would now fall to Antony. The menace was clear. The case of Gaul is particularly interesting. So much of the fighting and diplomacy of the last two years had been, in one way or another, a struggle for Gaul: and the province's strategic importance was very clear.[11] With hindsight, we always associate Antony with the East; Octavian's propaganda was to make great play with his oriental degeneracy. But nothing suggests that Antony yet planned any extended stay in the East. Naturally, he eyed its riches and prestige; he might of course have to play Sulla over again; but it was just as likely that he would return peaceably, as Pompey had returned in the sixties, to new power and authority in the West. In that case, and in the likely event of the triumvirs eventually falling out, Gaul would prove vital. Its governor would be Calenus, with eleven legions: Antony could rely on him. And, even if the Cisalpina were technically part of Italy, that too would not be out of Antony's control: Pollio was to be there, and he too had veterans under his command. The trusty Ventidius would also be active in the West, perhaps in Gaul, perhaps in Italy.[12] In the event Antony's possession of Gaul came to nothing, for Octavian took it over bloodlessly on Calenus' death in 40. It was that important historical accident that would turn Antony decisively towards the East. But, for the moment, possession of Gaul kept all his important options free.
