Battle of Arvandj (287 BC)

The battle of Arvandj was a battle during the Seleukid-Atropatene War. Finding little resistance during his initial invasion, Seleukos I Nikator pushed deep into Atropatene. There he found the Atropatenean army, but the difficult terrain, high mobility of the Atropatenean army and great skill by which Oxyartes Atropatid wielded his forces made it difficult to engage in a decisive battle.

Second Battle of Arvandj
A year later, in march 286 BC, a cavalry detachment under Spithradates Frataraka was ambushed at Arvandj by Oxyartes Atropatid, who inflicted heavy casaulties on the units.
