Maratha Empire Dom Pedro Miguel de Almeida Portugal e Vasconcelos The siege of Alorna in 1746 was a military engagement that took place in India, between Portuguese forces under the command of the Viceroy of India, Dom Pedro Miguel de Almeida Portugal, and those of the Sawantwadi State then part of the Maratha Confederacy, which were defeated.

[8] In 1741, the Marathas overran the Bardez and Salcette districts of Portuguese Goa, being later forced to withdraw by the Viceroy, Marquis of Louriçal.

[9] An enemy of the Portuguese, the neighbouring Bhonsles of Sawantwadi, who were part of the Maratha Confederacy, were forced to make peace, but shortly afterwards renewed the hostilities against Goa, harassing its shipping and raiding its border territories.

By 10am, Portuguese boats bombarded a set of timber and earthen stockade the Bhonsles had erected by the river banks upstream and garrisoned with 300 men, which was captured by grenadiers.

After five hours of fighting, the fort was stormed by the Portuguese grenadiers, both via its gate, which was breached by gunpowder explosives, and taken by ladder assault.
