Cornwallis left India in 1793, and was succeeded by Sir John Shore. This well-meaning but feeble gentleman allowed both the Marathas and Tippoo to increase their strength at the expense of the Nizam, the ally of the British, and by his weakness encouraged Tippoo to cultivate relations with the French. In 1798 he was succeeded by a very different kind of man, Lord Mornington, better known as Marquess Wellesley, who speedily made up his mind that the anarchy outside the British dominions must cease, and that to this end British authority must become paramount in India. Tippoo Sahib, being the open ally of the French, was the first enemy to be attacked; and the command of the expedition was entrusted to General Harris with Colonel Arthur Wellesley, Mornington's younger brother, for one of his brigadiers. Harris, knowing Tippoo's trick of devastating his country before an invading army, had to think out some method of neutralising it, for his difficulties of transport and supply were frightful. In all he had 120,000 bullocks to draw supplies and stores for his army, and those bullocks must be fed, or the campaign would go for nothing. To protect them he was obliged to advance in a hollow square, two miles broad and seven miles deep, an extremely cumbersome formation; and yet his only resource was to make feints of an advance in one direction so that Tippoo should destroy the country in that quarter, and then swerve away to a district which Tippoo had spared. This device was successful. By much zig-zagging Harris reached Seringapatam in thirty-two days without mishap, and after a month's siege stormed the city for the last time. Tippoo was killed; Tanjore and the Carnatic were annexed to the British dominions; and Mysore was restored to the Hindu dynasty which had formerly ruled it. Arthur Wellesley was meanwhile left in civil and military command of the province, and during the next two years did excellent service in restoring order in southern India. In particular he took note of the superiority, for purpose of transport, of the Mysore bullocks, which can trot six miles an hour.
