Shortly after the news of Mutina, the provinces and armies of the East were consigned to Cassius in one act.Nor was this all. Octavianus remained in the neighbourhood of Bononia and awaited with equanimity the ruin of D. Brutus and the triumph of diplomacy among the Caesarian armies of the West. The confrontation with Lepidus was not long delayed. One of the lieutenants of Lepidus dispatched to Antonius during the War of Mutina remained in his company, another had studiously refrained from barring the road to Narbonensis. In March, Lepidus urged the Senate to accept his mediation; and Antonius publicly asseverated that Lepidus was on his side.
Mutinaの知らせが入ってまもなく１つの決議により属州と東方の軍隊がCassiusに委ねられた。OctavianusはまだBononia近郊に残り、落ち着いてD. Brutusの破滅と西側のCaesar派の軍隊の外交交渉の勝利を待っていた。Lepidusとの対立は長くは続かなかった。Mutinaの戦いの間、Antoniusの部隊に派遣されたLepidusの補佐官の1人は彼の部隊に残り、他の1人はNarbonensisに通じる道路を塞ぐのを故意にやめていた。3月、 Lepidusは元老院に対し、自分の仲裁を受け入れるよう促し、Antoniusは公然とLepidusは自分の味方だと公言した。
