Following this attack, Domitian, accompanied by Cornelius Fuscus, Prefect of the Praetorian Guard, personally arrived in Moesia, reorganized the province into Moesia Inferior and Moesia Superior, and planned a future attack into Dacia. To replenish their forces and greatly strengthen the Roman army in this territory, the IV Flavia from Dalmatia and two more legions, the I and II "Adiutrix", were moved to Moesia from the western provinces. The region of Sirmium was attached to Moesia Superior, in order to have a single command over the endangered Dacian frontier.
