The last battle in which Alexander the Great finally defeated the Persian kingdom?

Alexander the Great at that time already anticipated the triumph of victory over Tsar Darius 3. So in the fall of 331 BC, Greek and Persian armies met near Gaugamel. There, a decisive battle took place between Alexander and Darius 3. Despite the fact that the Persians gathered a huge army (about 250 thousand people), Alexander’s troops were able to withstand and deliver a serious blow to the very center of the Persian troops, which became the reason for the defeat of Darius, who in fear retreated from the battlefield.
