Aurangzīb removed Shāyista Khān from the viceroyalty and sent Jay Singh of Amber to the Deccan to punish Shivājī (1665). This raja by marvellously skilful diplomacy raised a complete ring of enemies round Shivājī and laid siege to the fort of Purandar, in which the families of the Marāthā officers had taken shelter. In two weeks he wrested the fortified hill of Vajragarh (Rudramāl) which commands the main terrace of Purandar, and advanced along the ridge connecting the two forts, while a strong flying column burnt and sacked the villages of Mahārāshtra. At last, finding the fort doomed, Shivājī personally visited Jay Singh and made with him the treaty of Purandar (22 June) by which he ceded to the emperor twenty-three forts (with lands yielding 400,000 *hūns*), and retained for himself only twelve forts (with territory worth 100,000 *hūns* a year), acknowledged himself a vassal of the emperor and promised to send a contingent of 5000 horse to serve in the Mughul ranks in the Deccan. In the invasion of Bījāpur that soon followed, he served the imperial cause with complete loyalty.
