Purandar and Vajragad were among the 23 forts which Shivaji had to give up in the treaty with Jaisingh. On 18th Mar 1670 CE, Nilopant Mujumdar launched an attack on both the forts. Killedar Sheikh Raziuddin was captured and the forts were won. Five years back Murarbaji had laid down his life at the same place. On that day, his death was avenged.
