How a strategic gamble at the Hellespont reshaped the fate of Alexander's empire
In 321 BC, the death of Alexander the Great triggered a brutal power struggle among his successors. When the veteran general Craterus attempted to invade Asia, Eumenes faced him with a clever tactical maneuver. The resulting clash at the Hellespont eliminated two major rivals and altered the course of history.
Following Alexander the Great's death in 323 BC, his vast empire descended into chaos as his generals, known as the Diadochi, vied for control. Perdiccas, who held the title of regent of the Asiatic Empire, sought to solidify his authority by attempting to marry Alexander’s sister, Cleopatra of Macedon. This ambition provoked a powerful coalition of rival successors to unite against him, leading to the deployment of Craterus to Asia to challenge Perdiccas and his allies.
To block this invasion, Perdiccas dispatched Eumenes and Neoptolemus to the Hellespont. However, internal friction undermined this mission when Neoptolemus, driven by jealousy, defected to join Craterus with a small force of cavalry. Despite this betrayal, Eumenes prepared for battle. Both sides deployed their infantry phalanxes in the center, with cavalry positioned on the wings. Craterus commanded a formidable force of veteran Macedonian infantry, while Eumenes relied on his superior numbers of cavalry, specifically avoiding the use of Macedonian troops against the highly popular Craterus.
Eumenes entrusted his cavalry wings to Pharnabazus and Phoenix of Tenedos, ordering them to charge immediately upon sighting the enemy to prevent any negotiations. The strategy proved decisive. The rapid cavalry assault shattered Craterus’ lines, leading to the death of the aged general in the ensuing chaos. Simultaneously, Eumenes engaged Neoptolemus in single combat, killing him. With their leaders fallen, the remaining infantry surrendered. Although the defeated soldiers initially agreed to serve under Eumenes, they soon defected under the cover of darkness to support Antipater. While the battle removed two significant contenders, it was merely one chapter in a conflict that would persist for four decades.
