Conquests and Guerrilla Warfare
The Art of Ganimi Kava
At seventeen, Shivaji captured his first fort. Over the next two decades, he would invent a revolutionary style of warfare, ganimi kava, the art of guerrilla tactics, that humiliated the mightiest armies of his age. From the killing of Afzal Khan to the daring raid on Shaista Khan, discover how a young warrior with a handful of Mavlas built an empire that the Mughals could not destroy.
The First Fort Falls
In 1645, two years before Dadoji Konddev's death, seventeen-year-old Shivaji made his first move. Without informing his father or his mentor, he took a small band of Mavla companions and captured Torna Fort, a neglected hilltop fortress in the Sahyadris.
The fort was poorly defended. Its Bijapur garrison barely resisted. But the message was revolutionary: a teenage Hindu had seized a Sultanate fortress and raised his own flag.
"I have taken what belongs to my people. Let those who object come and take it back."
Shahaji, his father, was furious. Serving the Bijapur Sultanate, he feared his son's recklessness would destroy the family. The Sultan was appeased with apologies and payments. But Shivaji had tasted independence, and he wanted more.
The Strategy of Forts
Between 1645 and 1659, Shivaji systematically captured fortress after fortress across the Sahyadri ranges. His strategy was clear:
| Element | Approach |
|---|---|
| Target Selection | Focus on neglected forts with weak garrisons |
| Intelligence | Use Mavla networks to map defenses and bribe guards |
| Timing | Strike during monsoons when reinforcements couldn't arrive |
| Speed | Capture quickly before the enemy could organize response |
| Fortification | Immediately strengthen captured forts with loyal garrisons |
By 1659, Shivaji controlled a network of hill forts stretching across the Western Ghats. Each fort was a base for further operations, a refuge in retreat, and a symbol of growing Maratha power.
Key forts captured in this period:
- Torna (1645), The first conquest
- Rajgad (1647), Became his first capital
- Kondana (later Sinhagad, 1648)
- Purandar (1648)
- Javli (1656), Required defeating the Maratha chief More
Ganimi Kava: The Art of Guerrilla Warfare

Shivaji's military innovation was ganimi kava, literally "enemy tactics" or what we now call guerrilla warfare. He fought not like a traditional Hindu king with elephant-mounted cavalry meeting the enemy in open battle, but like a mountain wolf:
