Western Chalukya Empire
The Chola dynasty and the Western Chalukya Empire maintained a large number of war elephants in the 11th and 12th century. The war elephants of the Chola dynasty carried on their backs fighting towers which were filled with soldiers who would shoot arrows at long range. The army of the Pala Empire was noted for its huge elephant corps, with estimates ranging from 5,000 to 50,000.
