He therefore spoke to his army and tried to persuade them to march further into India, but Coenus pleaded with him to change his mind and return, saying the men "longed to again see their parents, their wives and children, their homeland". Alexander, seeing the unwillingness of his men, agreed and turned back.

Why did Alexander decide to return home?

He had the dared elephants (Greeks were quite new to the use of Elephants in battle). So, men could not be persuaded to cross the Ganges. Understanding that his dreams would have to wait, Alexander decided to return back.

Who defeated Alexander in India?

King Porus of Paurava blocked Alexander's advance at a ford on the Hydaspes River (now the Jhelum) in the Punjab. The forces were numerically quite evenly balanced, although Alexander had more cavalry and Porus fielded 200 war elephants.
