After the fall of Lucknow Canning insisted that Sir Colin Campbell should take immediate action against the rebels in Oudh and Rohilkhand, and a number of petty and harassing operations were carried out by detached columns; but Campbell moved too slowly to bring his guerrilla opponents to book, and the rebellion was really brought to a conclusion by Sir Hugh Rose's brilliant campaign in Central India. The Central India Campaign. Though the two great princes of Central India, Sindhia and Holkar, wisely and fortunately remained true to the British, troops belonging to both of them joined the mutineers. The Gwalior contingent of Sindhia's army mutinied in the middle of June, and on the 1st of July Holkar's troops revolted at Indore, and the resident, Henry Durand, was forced to leave the residency. The rani of Jhansi also rose in rebellion, to become known as "the best man upon the side of the enemy." The rising in this quarter received little attention until January 1858, when Sir Hugh Rose was given the command of two brigades, to act in concert with Sir Colin Campbell, and he immediately began a campaign which for celerity and effectiveness has rarely been equalled in India. His principle was to go straight for the enemy wherever he found him, and pursue him until he had exterminated him. He was hampered by none of that exaggerated respect for the rebels which earned Sir Colin Campbell the nickname of Old Khabardhar (Old Take-Care); but carried to an extreme the policy of audacity. Advancing from Bombay Sir Hugh Rose relieved Saugor on the 3rd of February, after it had been invested by the rebels for upwards of seven months. On the 3rd of March he forced the pass of Madanpur, and took the whole of the enemy's defences in rear, throwing them into panic. On the 21st he began the siege of Jhansi, the stronghold of the mutineers in Central India, with a garrison of 11,000 men. During the course of the siege Tantia Topi, the most capable native leader of the Mutiny, arrived with a fresh force of 20,000 men, and threatened the British camp; but Sir Hugh Rose, with a boldness which only success could justify, divided his force, and while still maintaining the siege of the fort, attacked Tantia Topi with only 1500 men and completely routed him. This victory was won on the 1st of April, and two days later Sir Hugh carried Jhansi by assault. On the 1st of May the battle of Kunch was fought and won in a temperature of 110° in the shade, many of the combatants on both sides being struck down by heat apoplexy. On the 22nd of May the battle of Kalpi was won, though the European troops were hampered by defective ammunition and Sir Hugh himself here received his fifth sunstroke. In five months he had beaten the enemy in thirteen general actions and sieges, and had captured some of the strongest forts in India. News now arrived that the rebel army under Tantia Topi and the rani of Jhansi had attacked Sindhia, whose troops had gone over to the
