The rebels divided their forces into three parts. One was to invade Italy, which was not far from Nauportus (a Roman fort in present-day Slovenia); one had already entered the Roman province of Macedonia (present-day Greece); and the third fought in their home territories. They executed their plan swiftly, massacring Roman civilians and a sizable veteran contingent who were helpless in this remote area. They seized and pillaged Macedonia, creating general panic in Rome. Augustus, also alarmed, ordered a general levy, and recalled veterans. Rich families were ordered to supply freedmen in proportion to their income, which had not been done since the aftermath of the Battle of Cannae two centuries earlier. Augustus warned that the rebels could reach Rome in ten days if drastic action was not taken. He assigned command of the war to Tiberius. The Roman army was organized into several divisions to evade the united forces of the rebels. Outposts were placed to prevent them from breaking through to Rome, as well as to disrupt their supply lines.
