A huge battle fought between the forces of the twenty-five-year-old Macedonian king Alexander III, later called “the Great,” and Persia’s King Darius III. Alexander had already defeated Darius at Issus in northern Syria in 333 b. c. After capturing Palestine and Egypt, Alexander marched his army, consisting of some seven thousand cavalry and forty thousand infantry, northeastward into the Mesopotamian plains. Darius was waiting near the village of Gaugamela, about 70 miles (113km) from Arbil (or Arbela). The size of his army is uncertain, but it was likely at least three or four times larger than Alexander’s. The Greeks arrived to find that the Persians had cleared the plain of obstacles to make it easier for chariots and horsemen to maneuver. The Persians were already formed into lines; they remained in them throughout the night for fear the Greeks might attack under the cover of darkness. Alexander wisely refrained from such a risky maneuver and got a good night’s sleep.
The next day, perhaps October 1, Alexander opened the battle by leading the cavalry on his right wing sideways to the right, as if trying to outflank the enemy. Darius and his generals responded by sending troops from their center to deal with the battle forming on their far left (corresponding to Alexander’s right). Just as Alexander had anticipated, this eventually caused a large gap to form in the Persian center. And into that opening charged the main force of the Macedonian cavalry, led by Alexander himself. According to his principal ancient biographer, Arrian, the young king
Drove in his wedge [i. e., a wedgeshaped formation] and raising the
Battle cry pressed forward at the
Double straight for the point where Darius stood. A close struggle ensued.
. . . Alexander himself. . . vigorously pressed the assault, fighting hand to hand. . . . Darius, who now saw nothing but terrors all around him, was the first to turn tail and ride for safety. (Anabasis Alexandri 3.14)
Many of Darius’s troops followed him in flight. Meanwhile, other Persian units made it through the Greek lines and attacked the Greek baggage train. These soldiers were driven back by a reserve unit of Macedonian infantry, and soon the entire Persian army was in full retreat. Alexander chased Darius to Arbil but there found only the king’s abandoned chariot and bow. To call Alexander’s victory decisive would be an understatement. He lost only a few hundred men, whereas Persian losses numbered forty thousand or more. In a single stroke, Alexander and his men had brought the mighty Persian Empire to its knees and ensured that it could never recover.
