"Alexander had obtained from Phegeus (a tribe from modern region of Punjab; probably modern Bhangu tribe) a description of the country beyond the Indus: First came a desert (obviously, Great Indian Desert) which it would take twelve days to traverse; beyond this was the river called the Ganges (if we came from Indus side and crosses Great Indian Desert, first comes River Jumna, then River Ganges; then note this description to Alexander was given by a Punjabi tribe and in many Punjabi texts upto the modern times Ganga and Jumna were mentioned always together as Gang-Jaman; so this tribe is reffering to Ganga or Ganga-Jumna is not clear) which had a width of thirty stadia (3.5 miles, rough idea given by Punjabi tribe as this measurement is equal to 1 kos an Indian unit of length), and a greater depth than any other Indian river; beyond this again were situated the dominions of the nation of the Prasioi (Greek form of Indian word "Prachi", i.e. one from the East, even today people of Punjab refer to people from the Province of Uttar Pradesh and Bihar as "poorbias" i.e. Easterners) and the Gangaridai (probably Greek form of Indian word "Gangadri", Gangadri is a place where River Ganges descends into the plains), whose king, Xandrammes (probably Greek form of Indian word Chandrama), had an army of 20,000 horse 200,000 infantry, 2,000 chariots and 4,000 elephants trained and equipped for war.

 

 

"Next came the Ganges, the largest river in all India, the farther bank of which was inhabited by two nations, the Gangaridae and the Prasii, whose king Agrammes (probably Greek form of Indian name Agrani; Agrani means Chief or Leader in Indian Language) kept in field for guarding the approaches to his country 20,000 cavalry and 200,000 infantry, besides 2,000 four-horsed chariots, and, a troop of elephants which he said ran up to the number of 3,000"
