Was Alexander the Great’s most essential general a victim of his own success?
In short: Parmenion served as the steady, conservative anchor for Alexander the Great’s lightning-fast conquests. As second-in-command, he commanded the left wing in every major battle, providing the tactical balance that allowed Alexander to strike decisive blows. Yet, despite his loyalty, Parmenion was assassinated by his king without any proof of treason.
Parmenion rose to prominence under Philip II of Macedon, securing victories against the Illyrians and overseeing Macedonian influence in Euboea. By the time Alexander ascended the throne in 336 BC, Parmenion was already his most experienced general. He solidified his position by executing Attalus, a rival to Alexander’s succession, effectively clearing the path for the young king. In return, Alexander placed Parmenion’s family in key military roles, including his sons Philotas and Nikanor, and his son-in-law Coenus.
During the campaign against Persia, Parmenion acted as a tactical foil to Alexander. While the king favored aggressive, innovative maneuvers, Parmenion often advocated for caution. At the Battle of Granicus, ancient accounts conflict on whether he advised delay, but his presence was vital. At the Battle of Issus, his ability to counter the Persian attack was the primary reason for the Macedonian victory. Even at Gaugamela, his command of the left flank remained a critical component of the overall battle philosophy.
The relationship fractured in 330 BC after Philotas was convicted of conspiracy against Alexander. Though no evidence linked Parmenion to the plot, Alexander feared the potential threat posed by a disaffected general commanding a large army near the royal treasury. To prevent a revolt, Alexander dispatched assassins on racing camels to kill Parmenion in Media before the general could learn of his son’s execution. This swift, preemptive strike ended the career of the man who had been the backbone of the Macedonian military machine for decades.
