Seleucid versus Parthia – preparing for Magnesia 190 BC

Continuing my refresher exercise for pike versus blade, the combined Roman-Pergamene cavalry strength at Magnesia was estimated at 3,000 strong. This is dwarfed by Seleucid totals and thought it a good moment to field the Seleucid against a mobile opponent, Parthia. The battle was fought on the larger board with both commands increased to 18 elements. The Seleucid were invading the steppe lands of Parthia.

1 x General (4Kn), 1 x cataphract (4Kn), 4 x phalangites (4Pk), 1 x Theurophori (4Ax), 1 x Galatian (4Wb), 1 x elephant (El), 1 x scythed chariot (SCh), 2 x skirmishers (Ps).
Additional troops:
1 x cataphract (4Kn), 2 x phalangites (4Pk), 1 x elephant (El), 1 x Galatian |(4Wb), 1 x Asiatic skirmishers (Ps).

1 x General (4Kn), 2 x cataphracts (4Kn), 9 x nomad horse archers (LH).
Additional troops:
1 x cataphract (4Kn), 3 x nomad horse archers (LH), 2 x city militia archers (3Bw).

Recalling Alexander’s battle against the Scythian, the phalangites deployed in line and not their usual deeper columns. Behind them, the cavalry formed a reserve with the elephants and scythed chariots holding the left wing. Having deployed first, the Parthian deployed in five groups with ample spacing between each group. This proved beneficial as the Parthian quickly shifted their light cavalry to occupy the Seleucid left wing while the main threat would sweep the light troops from the hill exposing the phalangite line.

The Parthian assault on the Seleucid right was stemmed by the determined resistance of mercenary troops.

The battle for the hill cost the Parthian dearly in pip expenditure, leaving the Seleucid time to roll up the Parthian right to earn them a victory (6-4)

Swapping the role of defender-attacker, the Seleucid deployed first forming their battle line in echelon with a reserve formation posted on the hill to their rear. The Seleucid cataphracts formed to the left of the battle line had the elephants and chariots to their rear. In response, the Parthian formed a contiguous front with their foot archers positioned facing the Seleucid cataphacts.

Learning from the previous engagement, the Parthian would refrain from attacking both flanks, but concentrate on one; the Seleucid left. The Parthian battle line would keep pace with their foot archers and move steadily forward.

Seizing the initiative, the Seleucid phalangites struck first and despite their thin line, the sent the enemy horse recoiling back with the losses. During the same bound, the elephant and chariot re-positioned themselves between the Parthian light horse and their camp; this offered ample room for the cataphracts to attack the Parthian light horse inflicting more casualties.

A counter attack by Parthia proved costly as the Seleucid were able to contain each threat and retake the advantage on their bound resulting in another victory (6-2).


Command control posed less an issue for the Parthian commander, however, considering their mobility it is quite tempting to use or in this case mis-use flanking maneuvers. Integrating light horse among the cataphract has its risk as LH will flee if defeated by foot troops leaving the Parthian cataphract exposed. Consider also mounted will also recoil from solid foot on even combat scores, making the Parthian a difficult army to use. 

If there are any weak aspects of the the Seleucid army, then that would be the elephants and chariots. A simple ‘more than’ combat result will finish them both, hence their being tucked away in game two. 


  1. Thanks for posting.

    Really nice to see a LH heavy army in use, and will hope to remember about your experience with the flanking maneuvers, next time I field my Albanian army. Not as many LH as the Parthians(only five), but your word of caution should still come in handy.

  2. Christopher,
    Thank you for the comment.

    Not one to let a challenge slide by, I will do another cavalry battle, but this one is between Parthia and the Sassanid (III/69a). That is the Sassanid list for Ardashir’s campaign against Parthia, Rome and Armenia.

    This should appear early next week.
