In another fragment, Cassius Dio wrote that the Romans had learned that Tarentum was preparing for war against them and sent Gaius Fabricius Luscinus (one of the consuls for 282 BC) as an envoy to the cities allied with Rome to prevent a rebellion there. However, "these peoples" arrested him and sent men to the Etruscans, Umbrians, and Gauls, causing several of them to secede. He also wrote that the Tarentines had started the war but felt safe because the Romans pretended to be unaware of the Tarentines' plans because of their "temporary embarrassments." Cassius Dio did not clarify what the "temporary embarrassments" were. The Tarentines thought that they were not observed. They "behaved still more insolently and forced the Romans even against their will to make war upon them."
