Eumenes was a native of Cardia in the Thracian Chersonese, although he was suspected to be Scythian. At a very early age, he was employed as a private secretary by Philip II of Macedon until his death and by Alexander the Great, whom he accompanied into Asia. After Alexander's death (323), Eumenes took command of a large body of Greek soldiers fighting in support of Alexander's son, Alexander IV. In the ensuing division of the empire, Cappadocia and Paphlagonia were assigned to Eumenes; but as they were not yet subdued, Leonnatus and Antigonus were charged by Perdiccas with securing them for him. Antigonus, however, ignored the order, and Leonnatus vainly attempted to induce Eumenes to accompany him to Europe and share in his far-reaching designs.
Eumenes joined Perdiccas, who installed him in Cappadocia. When Craterus and Antipater, having subdued Greece in the Lamian War, determined to pass into Asia and overthrow the power of Perdiccas, their first blow was aimed at Cappadocia. Craterus and Neoptolemus, the satrap of Armenia, were completely defeated by Eumenes in a battle somewhere near the Hellespont in 321. Neoptolemus was killed, and Craterus died of his wounds.
After the murder of Perdiccas in Egypt by his own soldiers (320), the Macedonian generals condemned Eumenes to death, assigning Antipater and Antigonus as his executioners. Eumenes, betrayed to them by one of his own officers, fled to Nora, a strong fortress on the border between Cappadocia and Lycaonia, where he held out for more than a year until the death of Antipater threw his opponents into disarray. Antipater had left the regency to his friend Polyperchon instead of his son Cassander. Cassander, therefore, allied himself with Antigonus and Ptolemy, while Eumenes allied himself with Polyperchon. He was able to escape from Nora, and his forces were soon threatening Syria and Phoenicia.
In 318 BC Antigonus marched against him, and Eumenes withdrew east to join the satraps of the provinces beyond the Tigris River. After two indecisive victories at Paraitacene (317) and Gabiene (316), Eumenes was betrayed to Antigonus by officers under his command.
According to Plutarch and Diodorus, Eumenes had won the battle but lost control of his army's baggage camp thanks to his ally Peucestas' duplicity or incompetence. This baggage also included all the loot of the most decorated Macedonian veterans (called the Argyraspides, or Silver Shields)—treasure accumulated over 30 years of successful warfare. It contained not only gold and gems but the soldiers' women and children. Antigonus responded to a request for the return of the baggage train sent by Teutamus, one of their commanders, by demanding they give him Eumenes. The Silver Shields did just that.
Antigonus, according to Plutarch, starved Eumenes for three days, but finally sent an executioner to dispatch him when the time came for him to move his camp. Eumenes' body was given to his friends, to be burnt with honor, and his ashes were conveyed in a silver urn to his wife and children.
Despite Eumenes' undeniable skills as a general, he never commanded the full allegiance of the Macedonian officers in his army and died as a result. He was an able commander who did his utmost to maintain the unity of Alexander's empire in Asia, but his efforts were frustrated by generals and satraps both nominally under his command and under that of his enemies. Eumenes was hated and despised by many fellow commanders—certainly for his successes and supposedly for his Greek ethnicity and prior office as Royal Secretary. Eumenes has been seen as a tragic figure, a man who seemingly tried to do the right thing but was overcome by a more ruthless enemy and the treachery of his own soldiers.
