At the age of 17 Shivaji carried out his first military action by attacking and capturing Torna fort of the Bijapur kingdom, in 1645. By 1647 he had captured Kondana and Rajgad forts and had complete control of the Pune region.
By 1654 Shivaji had captured forts in the Western Ghats and along the Konkan coast. In a bid to sabotage this move of the Marathas under Shivaji's able leadership, Adilshah had his father - Shahaji arrested by deceitful means, and he sent one army against Sambhaji, Shivaji's elder brother at Bangalore (with Farradkhan at its head) and another against Shivaji at Purandhar (with Fattekhan at its head). However both Bhonsle brothers defeated the invading armies securing the release of their father. Afzal Khan, the great warrior, was then sent to destroy Shivaji, in an effort to put down what was seen by Bijapur as a regional revolt.
