Battle of Gaugamela

The Battle of Gaugamela, also called the Battle of Arbela, took place in 331 BC between the forces of the Army of Macedon under Alexander the Great and the Persian Army under King Darius III. It was the second and final battle between the two kings, and is considered to be the final blow to the Achaemenid Empire, resulting in its complete conquest by Alexander. The fighting took place in Gaugamela, a village on the banks of the river Bumodus, north of Arbela (modern-day Erbil, in Iraqi Kurdistan). Despite being heavily outnumbered, the Army of Macedon emerged victorious due to the employment of superior tactics and the clever usage of light infantry forces. It was a decisive victory for the League of Corinth, and it led to the fall of the Achaemenid Empire and of Darius III. Background In November 333 BC, King Darius III had lost the Battle of Issus to Alexander the Great, which resulted in the subsequent capture of his wife, his mother and his two daughters, Stateira II and Drypetis. Alexander's victory at Issus had also given him complete control of southern Asia Minor (modern-day Turkey). After the battle, King Darius retreated to Babylon where he regrouped with his remaining army that was there, on-site from a previous battle. Alexander fought at the Siege of Tyre (332 BC), which lasted from January to July, and the victory resulted in his control of the Levant. Alexander then again fought at the Siege of Gaza. Persian troop counts in Egypt were diminished due to many soldiers being removed to support the Battle of Issus and dying there. As a result, the Persian satrap of Egypt, Mazaces, peacefully surrendered to Alexander upon his arrival.
