When the Taepings reached Changsha they found the gates closed and the walls manned. They proceeded to lay siege to it; they cut off its supplies, and they threatened the garrison with extermination. They even attempted to carry it by storm on three separate occasions. During eighty days the siege went on; but the Taepings were then compelled to admit that they were as far from success as ever. They had suffered very considerable losses, including another of their Wangs, the Western King, and although it was said that the loss of the Imperialists was larger, they could better afford it. On the 1st December they accordingly abandoned the siege and resumed their march northwards. They crossed the Tungting Lake on boats and junks which they had seized, and secured the town of Yochow on the Yangtsekiang without meeting any resistance. Here they captured much war material, including a large supply of gunpowder left by the great Chinese Viceroy, Wou Sankwei, of the seventeenth century. From Yochow they hastened down the river. The important city of Hankow surrendered without a blow. The not less important town of Wouchang, on the opposite or southern bank of the river, was then attacked, and after a siege of a fortnight carried by storm. The third town of Hanyang, which completes the busy human hive where the Han joins the great river, did not attempt any resistance. These successes raised the Taepings from the depths of despair to the heights of hope. The capture of such wealthy places dispelled all their doubt and discouragement. They were able to repay themselves for the losses and hardships they had undergone, and the prize they had thus secured furnished ground for hoping for more. But even now it was no part of their mission to stand still. They waited at Hankow only long enough to attach to their cause the many thousands attracted to Tien Wang's flag by these successes. The possibility of pursuit by Tseng Kwofan at the head of the warlike levies of Hoonan, where each brave is considered equal to two from another province, was still present to their minds. But he unfortunately rested content with his laurels, while the Taepings swept like an irresistible wave or torrent down the valley of the Yangtsekiang.
