Panic over the Illyrian revolt breaks out in Rome and Augustus raises a second task force under Tiberius's nephew Germanicus.

To do this, he resorts to the compulsory purchase and emancipation of thousands of slaves in order to amass enough troops.

This is the first time such a measure has been taken since the aftermath of the Battle of Cannae two centuries earlier.

At one moment, in winter CE 6/7, ten legions are deployed and an equivalent number of auxilia (seventy cohors, ten ala and more than ten thousand veterans).

Many within the legions are Roman war veterans.

In addition, they are assisted by a large number of Thracian troops deployed by their King Rhoemetalces, a Roman amicus (ally), for a grand total of some one hundred thousand men.

Bato II is captured soon afterwards by Bato of the Daesitiates, whose assembly puts the Bato of the Breuci to death.

The Romans face further reverses on the battlefield and a bitter guerrilla war in the Bosnian mountains, but bitter fighting also occurs in southern Pannonia around Mons Almus (modern Fruška Gora) near Sirmium.

Bato of the Breuci in the summer of CE 8, after two years of war, surrenders his forces to Tiberius on the bank of the river Bathinus (probably the river Bosna).
