The war of the Austrian Succession, in which George II. took the side of the empress, while the French king supported her competitor, extended to the Eastern World. Labourdonnais, the governor of the French colony in the Mauritius, suddenly appeared before Madras, and, as the town and fort were not prepared for defence, both were surrendered on honorable terms. But Dupleix, the French governor of Pondicherry, denying the right of Labourdonnais to grant any terms, refused to ratify the capitulation, and directed Madras to be razed to the ground. With still greater disregard for public faith, he led the English who had capitulated through the town of Pondicherry, as captives gracing his triumphal procession, in the presence of 50,000 spectators. Clive escaped this outrage by flying from Madras in disguise; he took refuge at Fort St. David, a settlement subordinate to Madras, where he obtained from Major Lawrence, one of the best officers then in India, an ensign's commission in the service of the company.

Peace between England and France having been established, Madras was restored to its former owners. Clive, however, did not return to his civil pursuits; he occasionally acted as a writer, but he was more frequently employed as a soldier in the petty hostilities which arose between the English and the natives. Events, however, were now in progress, which made the French and English East India companies competitors for an empire, though neither understood the value of the prize for which they contended; and Clive, fortunately for his country and himself, was almost forced to take the position of a military commander.

To explain fully the position of India, at this period, would take far more pages than we can afford lines; a very brief sketch, may, however, help our readers to comprehend the course of events. India, in its entire extent, was nominally governed by the Emperor of Delhi, or, as he was generally, though absurdly, called in Europe, "the Great Mogul." Under him were several viceroys, each of whom ruled over as many subjects as any of the great sovereigns of Europe; and the delegates of these viceroys had a wider extent of territory than is included in most of the minor states of Germany. This empire began to lose its unity toward the close of the seventeenth century. The different viceroys, while professing a nominal allegiance to the crown of Delhi, established a substantial independence; several of their immediate vassals treated them as they had done the emperor; and several warlike tribes took advantage of this disorganization to plunder the defenceless provinces. Of these the most formidable were the Mahrattas, whose name was long the terror of the peninsula.

Dupleix, whose name has already been mentioned as the French governor of Pondicherry, was the first who conceived the possibility of establishing a European dominion on the ruins of the Delhi empire; and, for this purpose, he wisely resolved to attempt no direct conquest, but to place at the head of the different principalities, men who owed their elevation to his aid, and whose continuance in power would be dependent on his assistance. With this view he supported a claimant to the viceroyalty of the Deccan, and another to the subordinate government of the Carnatic; or, as the Indians term it, a rival nizam, and a rival nabob, against the princes already in possession of these territories. His efforts were equally splendid and successful; the competitors whom he had selected became masters of the kingdom, and he, as the bestower of such mighty prizes, began to be regarded as the greatest authority in India. The English were struck with astonishment, and, as there was peace with France, they were at a loss to determine on the line of conduct that they ought to pursue. Mohammed Ali, whom the English recognized as Nabob of the Carnatic, was reduced to the possession of the single town of Trichinopoly, and even that was invested by Chunda Sahib, the rival nabob, and his French auxiliaries. Under these circumstances Clive proposed to the Madras authorities the desperate expedient of seizing on Arcot, the capital of the Carnatic, and thus recalling Chunda Sahib from the siege of Trichinopoly. With a force of 200 Europeans and 300 Sepoys, under eight officers, four of whom had been taken from the counting-house, Clive surprised Arcot in the midst of a terrific storm, and the garrison fled without striking a blow. Being reinforced by large bodies of troops, the expelled garrison, swelled to the number of 3,000 men, formed an encampment near the town; but Clive took them by surprise in the night, slew great numbers, put the rest to flight, and returned to his quarters without a single casualty.

Chunda Sahib sent 10,000 men, including 150 French soldiers, under his son, Rajah Sahib, to recover Arcot. Clive's little garrison endured a siege of fifty days against this disproportionate force, and against the pressure of famine, which was early and severely felt. Nothing in history is equal to the proof of devotion which the native portion of this gallant little band gave to their beloved commander; the Sepoys came to Clive with a request that all the grain should be given to the Europeans, who required more nourishment than the natives of Asia, declaring that they would be satisfied with the thin gruel which strained away from the rice. Rajah Sahib at length made an attempt to take the place by storm; he was defeated with great loss, principally by Clive's personal exertions, upon which he abandoned the siege, leaving behind him a large quantity of military stores.

Clive followed up his victory with great vigor, and the government of Madras, encouraged by his success, resolved to send him with a strong detachment to reinforce the garrison of Trichinopoly. Just at this conjuncture, however, Major Lawrence returned from England and assumed the chief command. If Clive was mortified by the change, he soon overcame his feelings; he cheerfully placed himself under the command of his old friend, and exerted himself as strenuously in the second post as when he held the chief command. The French had no leaders fit to cope with the two friends, and the English triumphed everywhere. The besiegers of Trichinopoly were themselves besieged, and compelled to capitulate. Chunda Sahib fell into the hands of the Mahrattas, and was put to death at the instigation of his rival. The forts of Covelong and Chingleput were taken by Clive, though his forces consisted of raw recruits, little better than an undisciplined rabble. Dupleix, however, was not driven to despair, but still sought means of renewing the contest.

After the capture of Chingleput, Clive returned to Madras, where he married Miss Maskelyne, sister to the Astronomer Royal, and immediately after returned to England. He was received with great honors by the Court of Directors, and, through the influence of Lord Sandwich, obtained a seat in Parliament; but his election having been set aside, he again turned his thoughts toward India, where both the company and the government were eager to avail themselves of his services. The directors appointed him governor of Fort St. David; the king gave him the commission of a lieutenant-colonel in the British army; and thus doubly authorized, he returned to Asia in 1755.

The first service on which he was employed after his return to the East was the reduction of the stronghold of Gheriah. This fortress, built on a craggy promontory, and almost surrounded by the ocean, was the den of a pirate named Angria, whose ships had long been the terror of the Arabian seas. Admiral Watson, who commanded the English squadron, burned Angria's fleet, while Clive attacked the fastness by land. The place soon fell, and a booty of a hundred and fifty thousand pounds sterling was divided among the conquerors.

About two months after Clive had entered on his government at Fort St. David, intelligence was received of the destruction of the English settlement at Calcutta by Surajah Dowlah, the Nabob of Bengal. Although scarcely any resistance had been made, the English prisoners, 146 in number, were all thrust into a close and narrow apartment called the Black Hole, which, in such a climate, would have been too close and too narrow for a single prisoner. Their sufferings during the dreadful night, until death put an end to the misery of most, cannot be described; 123 perished before morning, and the survivors had to be dug out of the heap formed by the dead bodies of their companions.

The authorities at Madras, on receiving this intelligence, resolved to avenge the outrage; 900 Europeans and 1,500 Sepoys, under the command of Clive, were embarked on board Admiral Watson's squadron; the passage was rendered tedious by adverse winds, but the armament arrived safely in Bengal. Clive proceeded with his usual promptitude; he routed the garrison which the nabob had placed in Fort William, recovered Calcutta, and took Hoogly by storm. Surajah Dowlah, who was as cowardly as he was cruel, now sought to negotiate peace, but at the same time he secretly urged the French to come to his assistance. This duplicity could not be concealed from Clive and Watson. They determined accordingly to attack Chandernagore, the chief possession of the French in Bengal, before the force there could be strengthened by new arrivals either from the South of India or 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, and nearly five hundred European troops were among the prisoners.
