Clive, unwilling to face a coalition between the French and the nabob, was in favour of acceding to the nabob's orders. The treaty of neutrality with the French was drawn up, and would have been signed, had it not been for the obstinate refusal of Admiral Watson to agree to it. Between that officer and Clive there had never been any cordial feeling, and from the time of their first connection, at the siege of Gheriah, differences of opinion, frequently leading to angry disputes, had taken place between them. Nor was it strange that this should be so. Both were brave and gallant men; but while Watson had the punctilious sense of honor which naturally belongs to an English gentleman, Clive was wholly unscrupulous as to the means which he employed to gain his ends.

Between two such men, it is not singular that disagreements arose. Admiral Watson, impelled by feelings of personal dislike to Clive, often allowed himself to be carried to unwarrantable lengths. On the occasion of the capture of Calcutta, he ordered Captain Eyre Coote, who first entered it, to hold it in the king's name, and to disobey Clive's orders, although the latter had been granted a commission in the royal army as lieutenant colonel, and was, moreover, the chief authority of the Company in all affairs on land. Upon Clive's asserting himself, Admiral Watson absolutely threatened to open fire upon his troops. Apparently from a sheer feeling of opposition, he now opposed the signing of the treaty with the French, and several days were spent in stormy altercations.

Circumstances occurred, during this time, which strengthened the view he took, and changed those of Clive and his colleagues of the council. Just then, the news reached Suraja-u-Dowlah that Delhi had been captured by the Afghans; and, terrified at the thought that the victorious northern enemy might next turn their arms against him, he wrote to Clive, begging him to march to his assistance, and offering a lac of rupees a month towards the expense of his army.

On the same day that Clive received the letter, he heard that Commodore James and three ships, with reinforcements from Bombay, had arrived at the mouth of the Hoogly; and that the Cumberland, with three hundred troops, which had grounded on her way from Madras, was now coming up the river.

Almost at the same moment he heard, from Omichund, who had accompanied the nabob to Moorshedabad, that he had bribed the governor of Hoogly to offer no opposition to the passage of the troops up the river.

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.
