Hill forts

Hill forts played a key role in Shivaji's strategy. Ramchandra Amatya, one of Shivaji's ministers, describes the achievement of Shivaji by saying that his empire was created from forts. Shivaji captured important Adilshahi forts at Murambdev (Rajgad), Torna, Kondhana (Sinhagad), and Purandar. He also rebuilt or repaired many forts in advantageous locations. In addition, Shivaji built a number of forts, numbering 111 according to some accounts, but it is likely the actual number "did not exceed 18." The historian Jadunath Sarkar assessed that Shivaji owned some 240–280 forts at the time of his death. Each was placed under three officers of equal status, lest a single traitor be bribed or tempted to deliver it to the enemy. The officers acted jointly and provided mutual checks and balances.
