In 36 BCE, Mark Antony drove into Atropatene and Media with grand plans and a vast siege train—only to see it destroyed by Parthian cavalry. Under relentless arrows, he retreated through Armenia, men freezing at night and bleeding by day. Prestige demanded a response; the target would be Armenia.

What Happened

Mark Antony, heir to Caesar’s armies and eastern command, set out to erase the memory of Carrhae. He advanced from Antioch through Armenia toward Atropatene, towing a massive siege train meant to batter Parthian-held cities into submission. Plutarch’s Antony wrote the tragic sequence: mobile Parthian and allied Median horse found the lumbering column and destroyed it, burning towering engines before they ever touched a wall [3].

Without rams and towers, the Roman plan unraveled. Horse archers encircled marching columns, the air quivering with shafts. By day, the hiss of arrows; by night, frost and thin rations. Antony’s men staggered across the Araxes and back toward Artaxata, cavalry snapping at their flanks and rear. The legions still fought like legions, but the battlefield had been chosen by the wrong army [3].

Antony was no Crassus in one respect—he extracted the bulk of his force. Yet he returned to Antioch with prestige in tatters and no cities to show for thousands of casualties. The blue of the eastern sky mocked the scarlet stains in the snow along mountain passes.

Plutarch lingers on the aftermath. Antony, furious at Armenian kingship’s wavering support, looked for compensation in ritual and revenge. The problem of the East could not be solved by siege alone; it could be answered, for a season, with a diadem seized from a neighbor [3].

Why This Matters

Antony’s failure reaffirmed the Parthian advantage in mobility. Destroying the siege train made Roman engineering irrelevant, proving again that campaigns had to be paced by rivers, depots, and allied cavalry if they were to succeed beyond the Euphrates [3].

The episode illuminates mobility versus siegecraft: the stronger Roman toolset collapses if the tools cannot be brought to the wall. It also pushed Antony toward a prestige play in Armenia, trading conquest for spectacle [3].

His pivot to Armenia set a template Rome would revisit: when victory in Mesopotamia proved elusive, control of the Armenian throne became the lever of choice.
