The defection of the Triads put an end to the idea of attacking Canton, and the Taepings marched to attack Kweiling, where the Imperial Commissioners still remained. Tien Wang's assault was repulsed with some loss, and, afraid of discouraging his troops by any further attempt to seize so strong a place, he marched into Hoonan. Had the imperial commanders, who had shown no inconsiderable capacity in defense, exhibited as much energy in offensive measures, they might then and there have annihilated the power of the Taepings. Had they pursued the Taeping army they might have harassed its rear, delayed its progress, and eventually brought it to a decisive engagement at the most favorable moment. But the Imperial Commissioners did nothing, being apparently well satisfied with having rid themselves of such troublesome neighbors. The advance of the Taepings across the vast province of Hoonan was almost unopposed. The towns were unprepared to resist an assailant, and it was not until Tien Wang reached the provincial capital, Changsha, that he encountered any resistance worthy of the name. Some vigorous preparations had been made here to resist the rebels. Not merely was there a garrison in the place, but it so happened that Tseng Kwofan, a man of considerable ability and of an influential family, was residing near the town. Tseng had held several offices in the public service, and, as a member of the Hanlin, enjoyed a high position and reputation; but he happened to be at his own home in retirement in consequence of the death of a near relation when tidings of the approaching Taepings reached him, and he at once made himself responsible for the defense of Changsha. He threw himself with all the forces his influence or resources enabled him to collect into that town, and at the same time he ordered all the militia of the province to collect and harass the enemy. He called upon all those who had the means to show their duty to the state and sovereign by raising recruits or by promising rewards to those volunteers who would serve in the army against the rebels. Had the example of Tseng Kwofan been generally followed, it is not too much to say that the Taepings would never have got to Nankin. When the rebels reached Changsha, therefore, they found the gates closed, the walls manned, and the town victualed for a siege. They attempted to starve the place into surrender, and to frighten the garrison into yielding by threats of extermination; but when these efforts failed they delivered three separate assaults, all of which were repulsed. After a siege of eighty days, and having suffered very considerable losses, the Taepings abandoned the attack, and on the 1st of December resumed their march northward, which, if information could have been rapidly transmitted, would have soon resulted in their overthrow. On breaking up from before Changsha they succeeded in seizing a sufficient number of junks and boats
