313 BCE
Aristodemus and his mercenary army (recruited the year prior) cross over to the Peloponnese and fight Alexander, the son of Polyperchon, at Cyllene, and liberate Patrae and Aegium from Cassander's garrisons. Aristodemus then returns to Aetolia, leaving a sizeable force in the Pelopponese who help the city of Dyme eject its garrison, despite a failed intervention by Alexander. Philip marches into Acarnania to prevent Aeacides from linking up with the Aetolians. Philip defeats Aeacides in battle, killing many Epirotes and capturing 50 leading supporters of Aeacides, sending them as prisoners to Macedon. Aeacides, with the remnant of his forces, joins the Aetolians. Philip catches up to Aeacides and the Aetolians at Oeniadae and defeats them in battle. Aeacides, who was wounded in the Battle of Oeniadae, dies a few days later. The remaining Aetolian army takes refuge in the surrounding mountains. The consul Gaius Junius Bubulcus Brutus is credited with the capture of Nola, Atina, and Calatia by some sources.
Geopolitics & Diplomacy
Conflict & Security
- Cassander, hearing of Aristodemus' success with the Aetolians, marches south in force, persuades the Acarnanians to ally with him, and campaigns successfully along the Adriatic coast; capturing Apollonia and defeating the Illyrian king Glaucius. At the end of the year Cassander returns to Macedon.source
- Deinocrates, the leader of the Syracusan exiles, sends envoys to the Carthaginians to ask them for help against Agathocles, the tyrant of Syracuse. The Carthaginians, fearing for their own possessions in Sicily, send a large force to the island.source
- Becoming tired of Macedonian rule, the people of Epirus recall their former king Aeacides (who until then had been campaigning with his old ally Polyperchon in the Peloponnese). Cassander immediately sends an army against him under his brother Philip, who is diverted from invading Aetolia.source

Eupolemus, one of Prepelaus' lieutenants, is sent with 8,000 infantry and 200 cavalry. However, some deserters from Eupolemus' strike force betray their plans to Ptolemy who quickly gathers 8,300 infantry and 600 cavalry from their winter quarters and marches against Eupolemus.
