The resurgent Maratha Confederacy emerging from Maharashtra quickly repulsed the Mughals and subjugated them to the confines of Delhi.

However, due to their relentless attacks and raids the Nawab would be more partial towards signing the treaty eventually agreeing to cede Orissa to the Maratha Confederacy to ensure peace for both states.

However, Nawab Alivardi Khan successfully repelled the invasion, although not without the unfortunate consequence of Murshidabad and Hooghly suffering from plundering.

[11] By way of the jungles of north Birbhum and the Khargpur hills (south of Mungir), Raghoji arrived near Fatua which he pillaged heavily, and then turned south-west, plundering Shaikhpura and many villages in the Tikari zamindari, till he struck the Son river.

[12] The Battle of Burdwan oversaw Alivardi Khan heavily repulsing and defeating the Janoji Bhonsle led Marathas.

An army was amassed to defend against the invading Maratha forces at Orissa after the dismissal of Mir Jafar by Alivardi Khan.

Alivardi Khan was able to break the Afghan lines and make them retreat through the use of war elephants by his eager generals and eventually he won the battle.

[7] During that period of invasion by the Marathas, warriors called as "Bargis", perpetrated atrocities against the local population of Bengalis and Biharis.

[23][6] The atrocities devastated Bengal's economy, as many of the people killed in the Bargi raids included merchants, textile weavers,[6] silk winders, and mulberry cultivators.

[7] The Cossimbazar factory reported in 1742, for example, that the Bargis burnt down many of the houses where silk piece goods were made, along with weavers' looms.

Industries such as agriculture and trade were dislocated and a large number of people migrated from Western Bengal to the Northern and Eastern districts.
