Suraj-ud-Dowlah, exasperated by this breach of neutrality within his own dominions, took the side of the French.
After a few rounds of artillery fire, Suraj-ud-Dowlah fled, and the road to Murshidabad was left open.
Bharatpur rose into importance under Suraj Mall, who bore a conspicuous part in the destruction of the Delhi empire.
Suraj Mall raised the Jat power to its highest point; and Colonel Dow, in 1770, estimated the raja's revenue (perhaps extravagantly) at £2,000,000 and his military force at 60,000 or 70,000 men.
After the invasion of Mahmud of Ghazni the city fell into insignificance till the reign of Akbar; and thenceforward its history merges in that of the Jats of Bharatpur, until it again acquired separate individuality under Suraj Mal in the middle of the 18th century.
Ali Vardi Khan died in 1756, and was succeeded by his grandson, Suraj-ud-Dowlah, a youth of only nineteen years, whose ungovernable temper led to a rupture Black Hole of Calcutta.
Calcutta was retaken by Clive and Admiral Watson on the 2nd of January 1757, and on the 23rd of June, Suraj-ud-Dowlah, routed at Plassey, fled to Rajmahal, where he was captured.
He was put to death on the 4th of July 1757 at Murshidabad, by order of Miran, son of Mir Jafar, who had conspired against Suraj-ud-Dowlah and had been present at Plassey without taking part in the battle.
The chief event in the history of Calcutta is the sack of the town, and the capture of Fort William in 1756, by Suraj-udDowlah, the nawab of Bengal.
Thus in 1 757 it was the first to be taken by Suraj-ud-dowlah, the nawab; and the resident with his assistant (Warren Hastings) were taken as prisoners to Murshidabad.
