Sangram Durga is a land fort situated at Chakan, Pune, India. It is famous for its defense by Firangoji Narsala a renowned Maratha warrior and military leader in the army of Shivaji, a Maharaja of the Maratha Empire, against a Mughal army led by Shaista Khan in 1660 .
Firangoji was a Killedar(commander) of this fort in Chakan (Pune). When Shaista Khan invaded Pune with a lakh of soldiers, he selected Sangram Durga as the first target. He attacked the fort with 10,000 soldiers. Firangoji Narsala was prepared for this attack, despite only having 200 soldiers at his disposal. Just before this attack Shivaji had asked his commander to leave the fort, however Firangoji decided not to abandon the fort and instead started a fierce guerrilla war against the Mughals and defended the fort for almost two months.
The Mughals tried another way of taking the fort. They dug a tunnel up to the fort; which was a challenge because of the water around it. They filled this tunnel with explosives and blew up the wall of the fort. This was a major setback for Firangoji and his soldiers; 75 soldiers died in this attack. The Mughal army rushed into the fort; fierce fighting ensued and many Maratha soldiers were killed.
Shaista Khan was astonished by Firangoji's bravery, and offered him Mughal Sardari[disambiguation needed]. Firangoji refused to accept it and instead Shaista Khan gave him and his soldiers safe passage. Firangoji came to meet Shivaji and apologised for surrendering the fort. Shivaji, happy with him for having defended the small fort for almost 2 months said "if it took 60 days for Shaista Khan to take a small fort, imagine how many days will be required to capture an entire swarajya (kingdom)". Shivaji rewarded Firangoji and made him Killedar of the Bhupalgad fort .
