The attacking army was forced to come to the eventual site of this battle, near the towns of Urhai and Harran, due to a maneuver by the General Mazaeus, and lacked expected reinforcements which had been tied down in a war against King Agis III. The defending army may have been demoralized by a lunar eclipse shortly before this conflict, and its commanders included the satrap Bessus. The attacking general arrayed his flanks in an awkward manner, so as to encourage the enemy to attack them, resulting in a gap in the defending center, into which the Companion Cavalry charged, eventually capturing Queen Sisygambis and causing Darius to flee. For ten points, name this third and final of Alexander the Great against the Persians.
