Clive was now ready to agree to Admiral Watson's views, and to advance at once against Chandranagore; but the admiral again veered round, and refused to agree to the measure, unless the consent of the nabob was obtained. He wrote, however, himself, a threatening, and indeed violent letter to the nabob, ordering him to give his consent. The nabob, still under the influence of his fears from the Afghans, replied in terms which amounted to consent, but the very next day, having received news which calmed his fears as to the Afghans, he wrote peremptorily, forbidding the expedition against the French. This letter, however, was disregarded, and the expedition prepared to start. It consisted of seven hundred Europeans and fifteen hundred native infantry, who started by land; a hundred and fifty artillery proceeding in boats, escorted by three ships of war and several smaller vessels, under Admiral Watson. The French garrison consisted only of a hundred and forty-six French, and three hundred Sepoys. Besides these were three hundred of the European population, and sailors of the merchant ships in port, who had been hastily formed into a militia. The governor, indignant at the duplicity with which he had been treated, had worked vigorously at his defences. The settlement extended along the river banks for two miles. In the centre stood the fort, which was a hundred and twenty yards square, mounting ten thirty-two pounder guns on each of its four bastions. Twenty four-pounder guns were placed on the ramparts, facing the river on the south. On an outlying work commanding the watergate eight thirty-two pounders were mounted. Monsieur Renault set to work to demolish all the houses within a hundred yards of the fort, and to erect batteries commanding the approaches. He ordered an officer to sink several ships in the only navigable channel, about a hundred and fifty yards to the south of the fort, at a point commanded by the guns of one of the batteries. The officer was a traitor. He purposely sank the ships in such a position as to leave a channel, through which the English ships might pass; and then, seizing his opportunity, deserted to them.
