As all the central part of Asia now acknowledged his rule, he next went down into India, where he found King Porus, the bravest adversary he had ever met. This king, whose realm was in the northwestern part of India, came against Alexander with a very large army. In the ranks were many elephants, trained to crush the enemy beneath their huge feet, and bearing on their broad backs wooden turrets filled with brave fighting men and good archers.
In spite of these elephants, which at first awakened great fear in the Greek soldiers, the Macedonian phalanx won the victory as usual, and Porus was made prisoner. He was led into the presence of Alexander, who haughtily asked him how he expected to be treated. “Like a king!” was the proud reply.
This answer so pleased Alexander, that he not only set Porus free, but even allowed him to keep his kingdom, after he had sworn to be the faithful subject of his conqueror.
Alexander, having thus won the help and affection of Porus, made war against several other Indian kings, and continued his advance toward the south. In one of these battles he lost his faithful steed Bucephalus, which had borne him safely through many a fight.
Alexander felt this loss deeply, and not only had a monument built over his remains, but also founded a city near by, which was called Bucephala.
