In summer 599, the East Roman Emperor Maurice sent his generals Priscus and Comentiolus to the Danube front against the Avars.

Unwilling at first to leave the city without Comentiolus, Priscus was soon forced to appear in the camp, as the Avars were harassing it in the absence of the generals.

This engagement was followed by two other great battles in the next ten days, in which the strategy of Priscus and the tactics of the Roman army were brilliantly successful.

Priscus subsequently pursued the fleeing Khagan and invaded the Avar homeland in Pannonia, where he won another series of battles on the banks of the River Tisza.

Priscus's victories decided the war for the Romans and ending, for a time, the Avar and Slavic incursions across the Danube.
