"Alexander's march east put him in confrontation with the Nanda Empire of Magadha and the Gangaridai of Bengal. According to the Greek sources, the Nanda army was supposedly five times larger than the Macedonian army.[5] His army, exhausted, homesick, and anxious by the prospects of having to further face large Indian armies throughout the Indo-Gangetic Plain, mutinied at the Hyphasis (modern Beas River) and refused to march further east. Alexander, after a meeting with his officer, Coenus, and after hearing about the lament of his soldiers,[6] eventually relented,[7] being convinced that it was better to return. This caused Alexander to turn south, advancing through southern Punjab and Sindh, along the way conquering more tribes along the lower Indus River, before finally turning westward.[8]
Alexander died in Babylon on 10 or 11 June 323 BC. In c. 322 BC, one year after Alexander's death, Chandragupta Maurya of Magadha founded the Maurya Empire in India. "
