Background edit

Parthia had been Seleucid territory until 245 BC, when, following the death of Antiochus II and the subsequent seizure of the Seleucid capital Antioch by the Egyptians, the governor Andragoras had taken the opportunity to declare his independence. He was soon overthrown by the Parni tribe, led by Arsaces the First, who then claimed the kingship of Parthia. The Parni would rule Parthia unopposed for 3 decades.

Prelude edit

Having ended hostilities with Egypt, the Seleucid monarch Antiochus the Great sought to regain his empire's lost eastern territories. In early 209 BC he entered Media and began preparing to cross a stretch of waterless desert (most likely the Sirjan salt desert), which if successfully traversed would lead him to the Parthian capital Hecatompylos. The current Parthian king Arsaces the Second sent men to destroy the main underground wells along the route, but they were met and dispersed by 1000 Seleucid horsemen led by the commander Nicomedes.[2] Antiochus was then able to cross the desert and seize Hecatompylos. After a brief stay in the capital he set off in pursuit of Arsaces' much smaller Parthian army, which had retreated to find a more advantageous battle site.[3] They travelled as far as the Alborz mountains in the neighbouring region of Hyrcania, which were navigable only by narrow passes. In the primary pass, over Mt Labus, the Parthians prepared to face Antiochus.

Battle edit

Knowing that he could not force the pass, Antiochus split his army into many companies which took different, smaller routes over the mountains. In front was a detachment of Cretan shields led by Polyxenidas of Rhodes and many skirmishers led by a man only known as Diogenes. The rear was brought up mainly by infantry led by Nicolaus of Aetolia and the aforementioned Nicomedes.[4] The Parthians constructed blockades and positioned groups of soldiers on the different high points in the pass, and adverse weather caused additional trees and rocks to fall and block the Seleucids' way. An army entirely in phalanx formation could not have broken through, but the Parthians had not prepared for the light skirmishers led by Diogenes.[5] At each blockade Diogenes' company drove off the enemy with attacks from higher ground, allowing the Seleucids to move steadily up the mountain for seven days. On the eighth day the Parthians decided to abandon their ambush tactics and fight Antiochus in a body on the summit. The contest between the infantry forces was surprisingly close, with Diogenes again making a decisive contribution; he found an alternate route to the summit and panicked Arsaces' soldiers by appearing behind them. The Parthians were routed, allowing the Seleucids to enter Hyrcania.

Aftermath edit

Antiochus first took Tambrax, a large unwalled city. Most of its inhabitants fled to the walled Sirynx, which the Seleucids captured after a hard-fought siege.[6] After the fall of Sirynx Arsaces opened negotiations with Antiochus, reducing Parthia to a vassal of the Seleucid Empire. Two decades later the Seleucids were defeated by the Roman Republic at the Battle of Magnesia and began a century-long decline, allowing the Parthians to regain their independence and become a dominant power in the Middle East.
