In 313 BC, Cassander sends Prepelaus with an army to Caria in Asia Minor to aid his ally Asander.
They decide on a surprise attack on Ptolemy, the commander of Antigonus' forces in western Asia Minor.
In the middle of the night Ptolemy launches a surprise attack on Eupolemus' camp capturing the entire force with ease.
[4] Prepelaus is mentioned in 303 BC, when he held the important fortress of Corinth with a large force, but was unable to prevent its fall at the hands of Demetrius, and narrowly escaped capture.
