 She also captured Cassander's brother and a hundred of his partisans.Cassander soon blockaded and besieged Olympias in Pydna and one of the terms of the capitulation had been that Olympias's life would be saved, but Cassander had decided to execute her, sparing only temporarily the lives of Roxana and Alexander IV (they were executed a few years later in 309 BC).When the fortress of Pydna fell, Cassander ordered Olympias killed, but the soldiers refused to harm the mother of Alexander the Great.
