Eumenes was born in 361–360 BC in Cardia, a Greek colony on the Thracian Chersonese. His origin is shrouded in the mist of ancient gossip. Plutarch and Duris of Samos, drawing information from sources hostile to Eumenes, called his father a simple charioteer or even a poor flute-player. However, modern historians such as E. Anson rightly believe that this was merely an attempt to blacken the name of the great Greek. Most likely, his father Hieronymus was an influential citizen, connected by ties of hospitality with the Macedonian king Philip II.
In 346 BC, Cardia became an ally of Macedonia, and it was then that the young Eumenes entered the court. Philip II, who always had an eye for talent, noticed the boy’s agility and intelligence during pankration contests. Thus began his rise: for seven years he served as Philip’s personal secretary, or grammateus. Eumenes is credited with creating a powerful state chancery that controlled taxes, revenues, and the demographics of the growing kingdom. For the harsh Macedonian aristocrats, this “foreigner with a writing tablet” always remained an upstart, but Philip and his wife Olympias saw in him a loyal ally with no ambition to seize the throne.
After Philip’s assassination in 336 BC, Alexander not only kept Eumenes in office but promoted him to archigrammateus. For all thirteen years of the legendary campaign, Eumenes was the king’s shadow. He kept the Royal Ephemerides — daily chronicles recording every word and action of the monarch. Unlike the philosopher Callisthenes, Eumenes was the ideal bureaucrat: he omitted facts that discredited the king and conducted diplomatic games with virtuosity.
His position was unique. On one side stood his friendship with Olympias and Craterus; on the other, sharp conflicts with the king’s favorite, Hephaestion. Once Hephaestion gave a house that Eumenes had chosen to some flute-player, which almost led to an open quarrel. Yet Alexander valued his secretary so highly that in 324 BC, at Susa, he gave him Artonis, the sister of his mistress Barsine, in marriage. In the same year, Eumenes made an incredible career leap: after Hephaestion’s death, he took the post of hipparch of the Companions, turning from an official into a combat commander of the guard cavalry.
Alexander’s death in 323 BC marked the beginning of the end. Chaos erupted in Babylon. The infantry led by Meleager demanded the accession of the mentally impaired Philip III Arrhidaeus, while Perdiccas’s cavalry insisted on waiting for the birth of Roxana’s son. Eumenes displayed extraordinary flexibility: it was he who acted as peacemaker, proposing a compromise — two kings and two regents.
At the division of the empire, Eumenes received Cappadocia and Paphlagonia. There was only one problem: these lands still had to be conquered from the local ruler Ariarathes. Perdiccas ordered Antigonus and Leonnatus to help Eumenes, but they ignored the command. Leonnatus even tried to draw Eumenes into an adventure involving marriage to Alexander’s sister Cleopatra and the seizure of power in Macedonia. Eumenes, understanding that this enterprise would end badly, secretly fled to Perdiccas, taking with him 5 talents from the treasury.
A grateful Perdiccas personally led an army into Cappadocia in 322 BC, defeated Ariarathes, and handed power to Eumenes. There the Greek showed himself to be an outstanding administrator: he created his own cavalry force of 6,000 local horsemen, becoming the only satrap with a personal army capable of opposing the Macedonian phalanx.
In 321–320 BC, the First War of the Diadochi broke out. The coalition of Ptolemy, Antipater, and Craterus opposed Perdiccas. Eumenes was appointed strategos autokrator of Asia. He had to hold back Craterus — the most popular commander in Alexander’s army.
It was a battle of minds. Eumenes knew that his Macedonian soldiers would not fight against Craterus, so he deployed foreign cavalry against him under the command of Pharnabazus. In the brutal battle, Eumenes personally met the traitor Neoptolemus in single combat and killed him. Craterus fell at the hands of an ordinary warrior. After his victory, Eumenes wept over the body of his old friend, but that victory became his curse. Upon learning of Craterus’s death, the Macedonian army in Egypt sentenced Eumenes to death in absentia.
After Perdiccas’s death, Eumenes was left alone against everyone. He became a “wandering knight,” maneuvering between satrapies. In 319 BC, Antigonus Monophthalmus defeated him at Orcynia because of the betrayal of the cavalry commander Apollonides. Eumenes, with 600 loyal warriors, shut himself inside the impregnable fortress of Nora.
The siege of Nora is an example of Eumenes’s incredible ingenuity. To prevent the horses from growing stiff in the cramped space, he ordered them to be suspended on straps so that their hooves barely touched the ground. The horses struggled, thereby training their muscles. In the winter of 319–318 BC, Antipater died, and the new regent Polyperchon, needing an ally, granted Eumenes an amnesty.
Eumenes left Nora, cleverly altering the wording of his oath to Antigonus so that it became an oath of loyalty to the kings. He was given control over the Argyraspides, the “Silver Shields” — Alexander’s elite veterans, who were invincible but extremely capricious. To manage these proud warriors, Eumenes devised a brilliant psychological move: he set up an empty throne of Alexander in the tent, convincing everyone that the spirit of the dead king himself guided their councils.
The Second War of the Diadochi turned into a duel between Eumenes and Antigonus Monophthalmus. In 317 BC, Eumenes won a brilliant victory at the River Coprates, filling the riverbed with the corpses of his enemies. Later, at the Battle of Paraetacene, the outcome remained uncertain, but Eumenes preserved his army.
The denouement came in 316 BC at the Battle of Gabiene. On the battlefield, Eumenes was winning: his Argyraspides literally swept away everything in their path. However, Antigonus carried out a hidden maneuver and captured the veterans’ baggage train. There were their wives, children, and all the gold accumulated over forty years of campaigns.
When the Argyraspides learned of this, their loyalty to the cause of imperial unity instantly evaporated. Led by Teutamus, they entered into negotiations with Antigonus and handed over their commander in exchange for their possessions. Eumenes begged his soldiers to kill him on the spot so that he would not fall into enemy hands, but his pleas went unanswered.
Antigonus hesitated for a long time. His son Demetrius begged him to spare such a talent, but most of the commanders demanded execution. In the end, Eumenes was killed in prison. Antigonus, who nevertheless respected his enemy, ordered his body to be burned with honors and his ashes sent to his family in a precious vessel.
With the death of Eumenes, the dream of Alexander’s united empire died as well. He was the only one who fought not for his own throne, but for the dynasty that had created him. The historian J. G. Droysen rightly believed that none of Alexander’s generals possessed the art of strategy to the same degree as this Greek secretary.
