Shortly, following his accession, Sambhaji began his military campaigns against neighbouring states. Sambhaji's attack on Burhanpur, and granting refuge to prince Akbar, Aurangzeb's fugitive son compelled the latter to move south with the Mughal army.
Attack on Burhanpur Bahadur Khan was in charge of the fort of Burhanpur who later entrusted Kakar Khan with the same. Kakar was performing the duty of collecting
jizya tax from the Hindu citizens of Burhanpur. The Jizya was collected and stored at the Burhanpur fort. Sambhaji plundered and ravaged
Burhanpur in 1680. His forces completely routed the
Mughal garrison and punitively executed captives. The Marathas then looted the city and set its ports ablaze. Sambhaji then withdrew into
Baglana, evading the forces of Mughal commander Khan Jahan Bahadur. Aurangzeb in response moved his court south to
Aurangabad and took over command of the Deccan campaign. The rebels were defeated and Akbar fled south to seek refuge with Sambhaji. Sambhaji's ministers including Annaji Datto, and other ministers took this opportunity and conspired again to enthrone Rajaram again. They signed a treasonable letter against Sambhaji in which they promised to join Akbar, to whom the letter was sent. Akbar gave this letter to Sambhaji.
Siege of Ramsej (1682) In 1682, the Mughals laid siege to the Maratha fort of
Ramsej, but after five months of failed attempts, including planting explosive mines and building wooden towers to gain the walls, the Mughal siege failed.
Mughal invasions of Konkan (1684) Aurangzeb then decided to attack the Maratha capital
Raigad Fort directly from the North and the South directions. He made a pincer attempt to surround the Maratha Capital that led to
Mughal invasions of Konkan (1684). The Mughals were badly defeated due to the Maratha strategy and the harsh climate of the region. These failures forced Aurangzeb to look away from the Maratha Empire and search for success against the
Qutb Shahi dynasty and
Adil Shahi dynasty. Under Sambhaji (1680–89) the Marathas ranged up and down western India.
Siddis of Janjira The Marathas under Shivaji came into conflict with the
Siddis, Muslims of
Abyssinian descent settled in India, over the control of the Konkan coast. Shivaji was able to reduce their presence to the
Janjira fort, a fortified island of
murud. Sambhaji continued the Maratha campaign against them, while at that time the
Siddis formed an alliance with the Mughals. At the start of 1682, a Maratha army later joined by Sambhaji personally, attacked the island for thirty days, doing heavy damage but failing to breach its defenses. Sambhaji then attempted a ruse, sending a party of his people to the Siddis, claiming to be defectors. They were allowed into the fort and planned to detonate the
gunpowder magazine during a coming Maratha attack. However, one of the female defectors became involved with a Siddi man and he uncovered the plot, and the infiltrators were executed. The Maratha then attempted to build a stone
causeway from the shore to the island, but were interrupted halfway through when the Mughal army moved to menace Raigad. Sambhaji returned to counter them and his remaining troops were unable to overcome the Janjira garrison and the Siddi fleet protecting it.
Portuguese and English Having failed to take Janjira in 1682, Sambhaji sent a commander to seize the Portuguese coastal fort of
Anjadiva instead. The Marathas seized the fort, seeking to turn it into a naval base, but in April 1682 were ejected from the fort by a detachment of 200 Portuguese. This incident led to a larger conflict between the two regional powers. In order to deny this support to the Mughals, Sambhaji invaded the Portuguese territories of Bardez and Salcette with 20,000 Maratha soldiers. According to an account by Padre Francisco de Souza, Marathas looted, destroyed Churches and raped Christian women. After they had completed sacking, they carried off with themselves many men, women and children whom they later sold to Arabs and Dutch. The sudden withdrawal of Sambhaji from Goa was cited as the result of a "miraculous intercession" by the saint. Meanwhile, in 1684 Sambhaji signed a defensive treaty with the English at Bombay, realising his need for English arms and gunpowder, particularly as their lack of artillery and explosives impeded the Maratha's ability to lay siege to fortifications. Thus reinforced, Sambhaji proceeded to take
Pratapgad and a series of forts along the
Ghats. Chikkadevraja later made treaties and rendered tribute to the Maratha kingdom during the conflicts of 1682–1686. Chikkadevraja however began to draw close to the Mughal Emperor and ceased to follow his treaties with the Marathas. In response, Sambhaji invaded Mysore in 1686, accompanied by his Brahmin friend and poet
Kavi Kalash.
Maratha Deshmukhs During his short reign, Sambhaji faced Mughal efforts to bring many Maratha Deshmukhs on their side, particularly after the demise of Bijapur and Golconda in 1686–87. Defections had become common by the end of his reign; according to Stewart Gordon, he had "badly alienated" deshmukh families by "burning villages to deny supplies to Goa" during the conflict with the Portuguese. The Deshmukh families that joined the Mughal service during Sambhaji's reign were the
Mane,
Shirke, Jagdale, and Yadav. There were also cases like that of the
Jedhe family where one brother joined Mughal service, and the other stayed loyal to Sambhaji. In 1683, Sambhaji learned from Prince Akbar that the faction opposing him was plotting to offer his kingdom to Akbar in exchange for his support against Sambhaji. Following this, Sambhaji tried and executed 24 members of influential families including top government ministers involved in the plot. == Capture, torture and execution ==
