In European history, Alexander was a legendary emperor. He used his wisdom and boldness to unify the whole of Greece, and he created the Macedonian phalanx platoon deployment method, leading the soldiers to be invincible on the battlefield, making European countries bow their heads and be subordinate.
He was hailed as the greatest military commander in European history, as he won almost every victory and swept through Europe. When he swept through the Middle East and flattened Persia, he was ambitious and spoke harsh words about conquering the East. When he led his army to the East in search of a great Eastern country, it was tragic.
It turned out that because no Europeans had ever arrived in China at that time, although there was a map, the path and direction marked on the map were far from China, and the result was that they came to India by mistake. Alexander was so excited that he mistakenly believed that India was the great power of the East, and immediately launched a war of conquest. The Macedonian phalanx that swept across Europe did not disappoint him. At the Battle of Haydas, Alexander defeated the Indian army, and even the Indian king was captured by him.
Later, in order to ensure victory, he released the Indian king and allowed him to continue to govern India. After the war, Alexander believed that the Central Asian plateau had reached the end of the world, and that the soldiers were tired of fighting and that there were logistical problems, so he had no choice but to return home.
