Andriscus' reign was defined to a significant degree by his military campaigns, due to his being in a constant state of war with Rome. After his conquest of the Kingdom, he enlarged the army and began campaigns to conquer [[Thessaly]], a key part of the realm of the old [[Antigonids]]. Initial resistance to him were from ''ad hoc'' forces of Roman allies in Greece, a few Roman units and legates in the region and some resistance from the remnants of Rome's client republics in Macedon, some elements of which seem to have survived for some time into his reign. Soon, however, the Romans sent a legion under the praetor Publius Juventius Thalna to defeat the pretender.{{sfn|Niese|1903|p=333}}{{sfn|MacKay|1968|p=38}}

Thalna, however, appears to have underestimated Andriscus' strength, not taking into account the fact that the king's army had grown dramatically since his enthronement.<ref>Florus, 1.30</ref> Andriscus attacked and fought him at an unspecified location in Thessaly (Dio gives it as "near the borders of Macedon"); details of the engagement are scarce, but Thalna was killed and his forces almost annihilated.<ref>Dio, XXI.71</ref>{{sfn|Niese|1903|p=333}} It was the worst defeat Rome would suffer at the hands of the Macedonians; Florus remarks on the irony of how "they that were invincible against real kings, were defeated by this imaginary and pretended king".<ref>Polybius, 37.9</ref><ref>Florus, 1.30</ref> The victory greatly increased the king's prestige; he obtained an alliance with [[Ancient Carthage|Carthage]], and his domestic popularity was increased dramatically, allowing him to stamp out republican resistance and conquer Thessaly.{{sfn|Niese|1903|pp=333-334}}{{sfn|Chisholm|1911}}{{sfn|MacKay|1968|p=37}}
