Well based on what I saw on the History Channel just now, Alexander the Great did win 1 battle in India, but as he wanted to attack the other kings, they all decided to unite to face him, his armies sensing that going against an Indian army who is 300k strong refuse to be drawn into another battle hence forced him to head back to Persia, apparently while he was in India, he contracted Malaria and died as he got back to Babylon.

I read another book on this subject in this book they said that he got poisoned by one of his courtiers in Babylon. So I guess as per where he died, the majority of the sources seem to indicate that it was in Babylon. Even the movie Alexander seems to show this. As to his death, that is very vague......

And I do think that Alexander the great is know as Iskandar Zulkarnian in our history text books, I don't see how can 1 claim otherwise
