A change came at last in the shape of war and captivity. As soon as the war of the Austrian Succession broke out the superiority of the French in power and influence tempted them to expel the English from India. Labourdonnais, the governor of the French colony of the Mauritius, besieged Madras, razed it to the ground, and carried its clerks and merchants prisoners to Pondicherry. Clive was among these captives, but he escaped in disguise, and returning to the settlement, threw aside his clerkship for an ensign's commission in a force which the Company was busily raising. For the capture of Madras had not only established the repute of the French arms, but had roused Dupleix, the governor of Pondicherry, to conceive plans for the creation of a French empire in India. When the English merchants of Elizabeth's day brought their goods to Surat, all India, save the south, had just been brought for the first time under the rule of a single great power by the Mogul Emperors of the line of Akbar. But with the death of Aurungzebe, in the reign of Anne, the Mogul Empire fell fast into decay. A line of feudal princes raised themselves to independence in Rajpootana. The lieutenants of the Emperor founded separate sovereignties at Lucknow and Hyderabad, in the Carnatic, and in Bengal. The plain of the Upper Indus was occupied by a race of religious fanatics called the Sikhs. Persian and Affghan invaders crossed the Indus, and succeeded even in sacking Delhi, the capital of the Moguls. Clans of systematic plunderers, who were known under the name of Mahrattas, and who were in fact the natives whom conquest had long held in subjection, poured down from the highlands along the western coast, ravaged as far as Calcutta and Tanjore, and finally set up independent states at Poonah and Gwalior.
