The relief of Kongyin, which was hard pressed, was the first task Gordon set himself; and as he could not leave his boat on account of his wound, the conduct of operations was attended with much difficulty. After obtaining several minor successes, and approaching to within a few miles of Kongyin, Gordon found it necessary to completely alter his plans, and to attack the Taepings in their headquarters at Waisso, before relieving the former place. He accordingly proceeded to Waisso with his artillery on board the flotilla, and his infantry marching by land. The latter, carried away by some trifling successes, attacked the Waisso stockades without his orders, and even without his knowledge; and having invited a reverse by their rashness and disobedience, rendered it complete by an inexcusable panic, during which the Taeping cavalry, not more than 100 strong, rode through the best regiment of the force; the rebels, carrying a sword in each hand, cut down the fugitives right and left. The pursuit lasted for three miles, and 7 European officers killed, 1 wounded, 252 men killed, and 62 wounded, represented the heavy loss in this disastrous affair. The survivors, many of whom had thrown away their arms, were so panic-stricken that Gordon had to retire, and to summon up fresh troops.
For this disaster Gordon held the officers, and not the men, to be blameworthy. They led the men into a false position, and then did not make the proper movements. If the men had only formed square, Gordon wrote, it would have been all right with them. After this Gordon waited to allow of his wound being thoroughly cured, and on 6th April he again appeared before Waisso. A large Imperial force also enveloped the place on all sides but one, which had been left apparently open and unguarded in the hope that the garrison would use it as a means of reaching a place of safety. The Imperialists had, however, broken all the bridges along this route, so that the Taepings would soon encounter serious difficulties to their progress, and admit of their being taken at a great disadvantage. Gordon approached the place with much caution, and he found it so strongly fortified on the south side, opposite his line of approach, that he moved round to the north in search of a more favourable point of attack. This simple manoeuvre so disconcerted the Taepings that they abandoned several of their stockades, which Gordon promptly seized; and finding that these in turn commanded others, he succeeded in carrying the whole of a most formidable position with little or no loss. The Taeping garrison fled in confusion and suffered heavily at the hands of the Imperial troops. It rallied on the camp before Kongyin, and the day after this success Gordon marched from Waisso to attack them. The Taepings were thoroughly disorganised, and apparently amazed at the number of their opponents, for the whole of the population rose against them in revenge for the outrages they had perpetrated. There was only one action, and that of an insignificant description, when the whole Taeping force before Kongyin broke into a rout. The Imperialist plan for retarding their retreat succeeded to admiration, and of more than 10,000 men not a tenth escaped from the sword of their pursuers.
