The Nabob behaved with all the faithlessness of an Indian statesman, and with all the levity of a boy whose mind had been enfeebled by power and self-indulgence. He promised, retracted, hesitated, evaded. At one time he advanced with his army in a threatening manner towards Calcutta; but when he saw the resolute front which the English presented, he fell back in alarm, and consented to make peace with them on their own terms. The treaty was no sooner concluded than he formed new designs against them.
He intrigued with the French authorities at Chandernagore. He invited Bussy to march from the Deccan to the Hoogley, and to drive the English out of Bengal. All this was well known to Clive and Watson. They determined accordingly to strike a decisive blow, and to attack Chandernagore, before the force there could be strengthened by new arrivals, either from the south of India, or from Europe. Watson directed the expedition by water, Clive by land. The success of the combined movements was rapid and complete. The fort, the garrison, the artillery, the military stores, all fell into the hands of the English. Near five hundred European troops were among the prisoners.
The Nabob had feared and hated the English, even while he was still able to oppose to them their French rivals. The French were now vanquished; and he began to regard the English with still greater fear and still greater hatred. His weak and unprincipled mind oscillated between servility and insolence. One day he sent a large sum to Calcutta, as part of the compensation due for the wrongs which he had committed, The next day he sent a present of jewels to Bussy, exhorting that distinguished officer to hasten to protect Bengal "against Clive, the daring in war, on whom," says his Highness, "may all bad fortune attend." He ordered his army to march against the English. He countermanded his orders.
He tore Clive's letters. He then sent answers in the most florid language of compliment. He ordered Watts out of his presence, and threatened to impale him. He again sent for Watts, and begged pardon for the insult. In the meantime, his wretched maladministration, his folly, his dissolute manners, and his love of the lowest company, had disgusted all classes of his subjects, soldiers, traders, civil functionaries, the proud and ostentatious Mahommedans, the timid, supple, and parsimonious Hindoos. A formidable confederacy was formed against him, in which were included Roydullub, the minister of finance, Meer Jaffier, the principal commander of the troops, and Jugget Seit, the richest banker in India. The plot was confided to the English agents, and a communication was opened between the malcontents at Moorshedabad and the committee at Calcutta.
In the committee there was much hesitation; but Clive's voice was given in favour of the conspirators, and his vigour and firmness bore down all opposition. It was determined that the English should lend their powerful assistance to depose Surajah Dowlah, and to place Meer Jaffier on the throne of Bengal. In return, Meer Jaffier promised ample compensation to the Company and its servants, and a liberal donative to the army, the navy, and the committee. The odious vices of Surajah Dowlah, the wrongs which the English had suffered at his hands, the dangers to which our trade must have been exposed, had he continued to reign, appear to us fully to justify the resolution of deposing him. But nothing can justify the dissimulation which Clive stooped to practise. He wrote to Surajah Dowlah in terms so affectionate that they for a time lulled that weak prince into perfect security. The same courier who carried this "soothing letter," as Clive calls it, to the Nabob, carried to Mr. Watts a letter in the following terms:
"Tell Meer Jaffier to fear nothing. I will join him with five thousand men who never turned their backs. Assure him I will march nigh and day to his assistance, and stand by him as long as I have a man left."
It was impossible that a plot which had so many ramifications should long remain entirely concealed. Enough reached the ear of the Nabob to arouse his suspicions. But he was soon quieted by the fictions and artifices which the inventive genius of Omichund produced with miraculous readiness. All was going well; the plot was nearly ripe; when Clive learned that Omichund was likely to play false. The artful Bengalee had been promised a liberal compensation for all that he had lost at Calcutta. But this would not satisfy him. His services had been great. He held the thread of the whole intrigue. By one word breathed in the ear of Surajah Dowlah, he could undo all that he had done. The lives of Watts, of Meer Jaffier of all the conspirators, were at his mercy; and he determined to take advantage of his situation and to make his own terms. He demanded three hundred thousand pounds sterling as the price of his secrecy and of his assistance. The committee, incensed by the treachery and appalled by the danger, knew not what course to take. But Clive was more than Omichund's match in Omichund's own arts. The man, he said, was a villain. Any artifice which would defeat such knavery was justifiable. The best course would be to promise what was asked. Omichund would soon be at their mercy; and then they might punish him by withholding from him, not only the bribe which he now demanded, but also the compensation which all the other sufferers of Calcutta were to receive.
His advice was taken. But how was the wary and sagacious Hindoo to be deceived? He had demanded that an article touching his claims should be inserted in the treaty between Meer Jaffier and the English, and he would not be satisfied unless he saw it with his own eyes. Clive had an expedient ready. Two treaties were drawn up, one on white paper, the other on red, the former real, the latter fictitious. In the former Omichund's name was not mentioned; the latter, which was to be shown to him, contained a stipulation in his favour.
