Eudemus: The man who assassinated Porus

Eudemus was one of Alexander the Great's generals. In 326 BC he was appointed by the king as the commander of Alexander's troops in India. After Alexander's death, Eudemus effectively controlled Alexander's northern Indian territories until he became involved in the Wars of the Diadochi during which he was captured and killed by Antigonus.

In 326 BC Eudemus was appointed by Alexander the Great to the command of the troops left in India, after the murder of the Alexander-appointed satrap Philip (son of Machatas) by his own mercenary troops in 326 BC. Alexander dispatched letters to India to Eudamus and also to Taxilas telling them to take charge of the district formerly under Philip, until Alexander could send a satrap to govern the district.[1]

After Alexander's death in 323 BC, Eudemus made himself master of the territories of the Indian king Porus and, according to Diodorus Siculus, treacherously put that monarch to death. As a result, Eudemus became very powerful and in 317 BC he was able to support Eumenes of Cardia in his war against Antigonus by providing a force of 500 horsemen, 300 footmen, and 120 elephants
