Events

By place

Macedonian Empire

* Eumenes and Antigonus, rivals to Cassander for control of Macedonia, meet in the Battle of Gabiene in Media to the northeast of Susa. Antigonus defeats Eumenes, with the aid of Seleucus and Peithon (the satraps of Babylonia and Media, respectively). The result is inconclusive. However, some of Eumenes' soldiers take matters into their own hands. Learning that Antigonus has captured many of their wives, children and the cumulative plunder of nearly 40 years of continuous warfare, they secretly open negotiations with Antigonus for their safe return. They hand over Eumenes and his senior officers to Antigonus in return for their baggage and families. Eumenes is put to death by Antigonus after a week's captivity.

Greece

* Cassander returns from the Peloponnesus and defeats Macedonia's regent Polyperchon in battle. Cassander blockades Olympias, mother of the late Alexander the Great, in Pydna, where she surrenders. Cassander takes Roxana and his son Alexander IV of Macedon into his custody.
* Olympias is condemned to death by Cassander, but his soldiers refuse to carry out the sentence. She is eventually killed by relatives of those she has previously had executed.
