On his wings, the Pauravan king stationed his chariots. He placed these animals before his infantry men, knowing that the Macedonian cavalry could not attack them because horses fear elephants unless they have had a special training. However, Porus still had one dangerous weapon: the elephants, an army unit that the Macedonians had never encountered before. The Indians were outnumbered and outclassed by the Macedonian army. He was defeated and killed, and Alexander started to move against the army of his father. As it turned out, Porus' son was no match for the Macedonians: during a thunderstorm, they crossed the Hydaspes, and the Indian chariots were unable to move through the rain-soaked mud. A bit more to the north, one of his sons was guarding the river, to make sure that Alexander would not outflank the Pauravans.

With his army, he had taken up a position on the east bank, intending to prevent Alexander's crossing. Hydaspes, possible location of the battlefield In May, the Macedonian army started to march to the Hydaspes. This was a grave error, because Alexander wanted to conquer all of India. Therefore, he refused to send envoys to Taxila to offer tokens of submission. However, for the time being, he seemed safe, because the approaching monsoon rains would make it impossible to cross the Hydaspes. To Porus, the arrival of the westerners was a great threat: after all, it was obvious that Omphis would use his allies in a war against Paurava. When the Macedonian conqueror Alexander the Great arrived in India in the spring of 326, he was welcomed by Omphis, the king of Taxila ( Takshaçila, near modern Rawalpindi), another kingdom in the Punjab and Porus' archenemy. Its capital may have been at the site now known as Lahore.

This state was situated between the rivers Hydaspes (modern Jhelum) and Acesines (Chenab).

The Greek/Latin name Porus is a rendering of the Indian Puru, the throne name of the ruler of the kingdom Paurava. Porus (Old Indian Puru): king in the eastern Punjab, defeated in 326 BCE by Alexander the Great.
