The Augustan Empire 43 BC

As relations had worsened, both Antony and Octavian had thought of wooing Sextus to their side. He was indeed worth wooing: Murcus had recently joined him, and Sextus' combined fleet now numbered some­thing like 250 ships.⁶⁷ Now, in the summer of 40, Octavian married Scribonia, the sister of Sextus' associate and father-in-law L. Scribonius Libo. But Sextus was always particularly distrustful of Octavian, and preferred to look to Antony: indeed, Antony's mother Iulia had fled confidently to Sextus after Perusia's fall, which may suggest that there was already some secret understanding. Sextus sent a prestigious escort, including Libo, to accompany her to Antony, and took the opportunity to offer him an alliance. Antony replied in measured but encouraging terms: if it came to war with Octavian, he would welcome Sextus as his ally; if he and Octavian made their peace, he would try to reconcile Octavian with Sextus as well. The understanding was sufficiently strong for Sextus to raid the Italian coast in Antony's support;⁶⁸ and a little later he occupied Sardinia and displaced Octavian's governor M. Lurius.

Octavian's ruthlessness in Italy, and perhaps his uncompromising response to L. Antonius' proclamations of freedom, had a further sequel. Domitius Ahenobarbus was also persuaded by the consul Pollio to join Antony, and his seventy ships joined Antony's two hundred as they sailed towards Brundisium. The alignments of early 43 had been paradoxically reversed. Republicans and Antony, with Sextus in the background, now stood together to confront the isolated Octavian; Brundisium might well turn out a Mutina in reverse, except that both Antony and Octavian were now much stronger. But, as in 43 but this time before serious bloodshed, Antony and Octavian were to find it prudent to come to terms.

There was some initial military activity. Brundisium, guarded by five of Octavian's legions, would not admit Antony's fleet, and was laid under siege; meanwhile Sextus was still continuing his raids on the coast. Octavian sent Agrippa to the town's aid, and himself swiftly followed; his troops were numerically superior⁶⁹ but reluctant, and some of them turned back. There was some skirmishing; Antony had the better of it. But by now deputations of each army were urging compromise, and it was not at all clear that either side would fight. The two men's friends began to discuss terms, with Maecenas negotiating for Octavian, Pollio

for Antony, and L. Cocceius Nerva as something of a neutral. Lepidus, unsurprisingly, was not represented. (He had been notably ineffectual in Italy during the Perusine War, and by now he was out of the way in Africa.) Thus was reached the Treaty of Brundisium (September 40).

The agreement closely duplicated the compact of Philippi, except for the important change that followed from Calenus' death. Octavian's occupation of Gaul was now recognized; he was also to have Illyricum. Antony was no longer simply entrusted with the organization of the East, he was also recognized as its master. The division of the world was correspondingly neater, with Antony controlling the East and Octavian the West: Scodra in Illyria was given unprecedented prominence as the dividing-point of the dominions. Lepidus might retain Africa, for what that was worth. Antony was to avenge Crassus by carrying through the Parthian War, Octavian to assert his claim to Sardinia and Sicily by expelling Sextus — unless (an interesting qualification) Sextus came to some agreement. There was also to be an amnesty for republican supporters. The consulships for the next few years were allocated; there was also a reallocation of legions, with Antony receiving some recom­pense for Calenus' army.[28]
