Explanation:

From the description of Bana it is known that Harsha carried his campaigns with an army of 5000 elephants, 20,000 horses, and 50,000 infantry. It is further revealed from his accounts that in six years of his incessant warfare Harsha brought the “Five Indies under his allegiance” and became the Lord Paramount of the north. Some historians believe that Five Indies refer to Saurashtra, Kanauj, Gauda, Mithila and perhaps a part of Orissa.
