Between 327 and 325 BC Alexander conquered territories in India eastward against Hydaspes and Indus, much through a split-and-rule tactic, but he had to defeat King Poros of Punjab in a dangerous battle. But at the Indus, which was the ancient eastern border of the Persian Empire, the soldiers refused to follow him further east. He then went down to the coast, sending part of the army under Admiral Nearkho’s sea route to the mouth of the Euphrates, while he himself led the bulk of the great suffering through the deserts of Baluchistan back to Babylon (in the year 324).
