Assassination Following what was so far a disastrous campaign, a mutiny broke out amongst Perdiccas' soldiers, who were disheartened by his failure to make progress in Egypt. Angry at his incompetence and probably colluding with Ptolemy, Perdiccas was murdered by his officers (Peithon, Antigenes, and Seleucus), probably in the summer of 320 BC, roughly three years after he had assumed the regency. His officers and the rest of his army defected to Ptolemy.
