intending to crush the growing power of shivaji maharaj, aurangzeb sent jaisingh of ambar, an experienced and powerful mughal sardar. he left delhi on 30th september 1664 and reached pune on 3rd march 1665. jaisingh's strategy was to isolate shivaji maharaj from his neighboring powers so that he would get neither help nor support from them, to prevent him from breaking out into the mughal territory, to devastate his homeland, and capture his forts. as per this strategy he was trying to provoke the adilshahi against shivaji maharaj. jaisingh was simultaneously instigating local rulers in the karnataka against the adilshah so that the latter would be unable to help shivaji maharaj. to the portuguese of goa and vasai, the dutch of vengurla, the british of surat, and the siddis of janjira, jaisingh suggested that they should start a naval campaign against shivaji maharaj. he also drew up a plan of capturing the forts in possession of maharaj. jaisingh and dilerkhan led siege to the fort of purandar. mughal forces were sent to various parts of swaraj to devastate the territories of the swaraj. maharaj endeavored to resist the mughals. when the mughals put the fort of purandar under siege, murarbaji deshpande fought with the greatest of courage. he died a hero’s death. realizing that in this conflict with the mughals, shivaji maharaj and his subjects had to face great losses, maharaj began talks for a treaty with jaisingh. a treaty between jaisingh and maharaj was signed in june 1665 which is known as the ‘treaty of purandar’. under the terms of the treaty, maharaj ceded twenty-three forts and adjacent areas yielding a revenue of four lakh hons to the mughals. he also assured the mughals of help against the adilshahi.
