Appian of Alexandria Civil Wars 3.14.96

[96] These things accomplished, Octavius formed plans for a reconciliation with Antony, for he had learned that Brutus and Cassius had already collected twenty legions of soldiers, and he needed Antony’s help against them. He moved out of the city toward the Adriatic coast and proceeded in a leisurely way, waiting to see what the Senate would do. Pedius persuaded the senators, after Octavius had taken his departure, not to make their differences with each other irremediable, but to be reconciled to Lepidus and Antony. They foresaw that such a reconciliation would not be for their advantage or for that of the country, but would be merely an assistance to Octavius against Brutus and Cassius. Nevertheless, they gave their approval and assent to it as a matter of necessity. So the decrees declaring Antony and Lepidus, and the soldiers under them, public enemies, were repealed, and others of a peaceful nature were sent to them. Thereupon Octavius wrote and congratulated them, and he promised to lend assistance to Antony against Decimus Brutus if he needed it. They replied to him at once in a friendly spirit and eulogized him. Antony wrote that he would himself take vengeance on Decimus for Caesar’s account and on Plancus ¹ for his own, and that then he would join forces with Octavius.
