Wou Sankwei drew up his forces at Yungping in a strong position near the scene of his recent victory; his front seems to have been protected by the river Zanho, and he calmly awaited the attack of Li Tseching, whose army far outnumbered his. Up to this point Wou Sankwei had not been joined by any of the Manchus, but a body was known to be approaching, and he was anxious to put off the battle until they arrived. For the same reason Li Tseching was as anxious to begin the attack, and, notwithstanding the strength of Wou Sankwei's position, he ordered his troops to engage without delay. Adopting the orthodox Chinese mode of attack of forming his army in a crescent, so that the extreme wings should overlap and gradually encompass those of the enemy, Li trusted to his numerical superiority to give him the victory. At one moment it seemed as if his expectation would be justified; for, bravely as Wou Sankwei and his army fought, the weight of numbers was telling its inevitable tale when a Manchu corps opportunely arrived, and attacking the Chinese with great impetuosity, changed the fortune of the day and put the army of Li Tseching to the rout. Thirty thousand men are said to have fallen on the field, and Li himself escaped from the carnage with only a few hundred horsemen. After this Li met with disaster after disaster. He was driven out of Shansi into Honan, and from Honan into Shensi. Wou Sankwei took Tunkwan without firing a shot, and when Li attempted to defend Singan he found that his soldiers would not obey his orders, and wished only to come to terms with Wou Sankwei. Expelled from the last of his towns he took refuge in the hills, but the necessity of obtaining provisions compelled him now and then to descend into the plains, and on one of these occasions he was surprised in a village and killed. His head was placed in triumph over the nearest prefecture, and thus ended the most remarkable career of a princely robber chieftain to be found in Chinese annals. At one time it seemed as if Li Tseching would be the founder of a dynasty, but his meteor-like career ended not less suddenly than his rise to supreme power was rapid. Extraordinary as was his success, Wou Sankwei had rightly gauged its nature when he declared that it had no solid basis.
