アエトリア同盟
In the spring of 209 BC, Philip received requests for help from his ally the Achaean League in the Peloponnesus who were being attacked by Sparta and the Aetolians. He also heard that Attalus had been elected one of the two supreme commanders of the Aetolian League, and rumours that he intended to crossover the Aegean from Asia Minor. It was due to this that King Philip decided to march south into Greece. In the First Battle of Lamia the Aetolian league suffered almost 1,000 casualties.
