I gave you an account of the taking of Chandernagore; the subject of this address is an event of much higher importance, no less than the entire overthrow of Nabob Suraj-ud-Daulah, and the placing of Meer Jaffier on the throne. I intimated in my last how dilatory Suraj-ud-Daulah appeared in fulfilling the articles of the treaty. This disposition not only continued but increased, and we discovered that he was designing our ruin by a conjunction with the French. To this end Monsieur Bussy was pressingly invited to come into this province, and Monsieur Law of Cossimbazar was ordered to return from Patna.

About this time some of his principal officers made overtures to us for dethroning him. At the head of these was Meer Jaffier, then Bukhshee to the army, a man as generally esteemed as the other was detested. As we had reason to believe this disaffection pretty general, we soon entered into engagements with Meer Jaffier to put the crown on his head. All necessary preparations being completed with the utmost secrecy, the army, consisting of about one thousand Europeans and two thousand sepoys, with eight pieces of cannon, marched from Chandernagore on the 13th and arrived on the 18th at Cutwa Fort. The 22nd, in the evening, we crossed the river, and landing on the island, marched straight for Plassey Grove, where we arrived by one in the morning.

At daybreak we discovered the Nabob's army moving towards us, consisting, as we since found, of about fifteen thousand horse and thirty-five thousand foot, with upwards of forty pieces of cannon. They approached apace, and by six began to attack with a number of heavy cannon, supported by the whole army, and continued to play on us very briskly for several hours, during which our situation was of the utmost service to us, being lodged in a large grove with good mud banks. To succeed in an attempt on their cannon was next to impossible, as they were planted in a manner round us, and at considerable distances from each other. We therefore remained quiet in our post, in expectation of a successful attack upon their camp at night.

About noon the enemy drew off their artillery, and retired to their camp.... We immediately sent a detachment accompanied with two field-pieces, to take possession of a tank [=an artificial pond] with high banks, which was advanced about three hundred yards above our grove, and from which the enemy had considerably annoyed us with some cannon managed by Frenchmen. This motion brought them out a second time; but on finding them make no great effort to dislodge us, we proceeded to take possession of one or two more eminences lying very near an angle of their camp.... They made several attempts to bring out their cannon, but our advance field-pieces played so warmly and so well upon them that they were always drove [=driven (archaic)] back. Their horse exposing themselves a good deal on this occasion, many of them were killed, and among the rest four or five officers of the first distinction, by which the whole army being visibly dispirited and thrown into some confusion, we were encouraged to storm both the eminence and the angle of their camp, which were carried at the same instant, with little or no loss.... On this a general rout ensued; and we pursued the enemy six miles, passing upwards of forty pieces of cannon they had abandoned, with an infinite number of carriages filled with baggage of all kinds. Suraj-ud-Daulah escaped on a camel, and reaching Moorshedabad early next morning, despatched away what jewels and treasure he conveniently could, and he himself followed at midnight with only two or three attendants.

It is computed there are killed of the enemy about five hundred. Our loss amounted to only twenty-two killed and fifty wounded, and those chiefly blacks. During the warmest part of the action we observed a large body of troops hovering on our right, which proved to be our friends; but as they never discovered themselves by any signal whatsoever, we frequently fired on them to make them keep their distance. When the battle was over they sent a congratulatory message, and encamped in our neighbourhood that night. The next day Meer Jaffier paid me a visit, and expressed much gratitude at the service done him, assuring me in the most solemn manner that he would faithfully perform his engagement to the English....
