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. Historians are divided as to what happened next. A. Mócsy suggests that after handing over the command to Fuscus, Domitian returned to Rome in the same year, while Fuscus cleared the Dacian invaders from the province.Mócsy (1974), p83. According to E. T. Salmon and M. Bunson, however, Domitian personally led the successful operations, then returned to Rome to celebrate a double triumph.Salmon (1944), p248.Bunson (1994), p181.

Defeat of Cornelius Fuscus

In the same year (86), after the initial success against the Dacians, Cornelius Fuscus crossed the Danube. However, his army was ambushed and destroyed while Fuscus himself died in the battle. Grumeaza has speculated that, after this victory, Diurpaneus received the name of
