A chief named Haida was the first to stir up the embers of internecine strife among the Niuche clans. To gratify his own ambition or to avenge some blood feuds, he obtained the assistance of one of the principal Chinese officers on the Leaoutung borders, and thus overran the territory of his neighbors. Encouraged by his first successes, Haida proceeded to attack the chief of Goolo, who was married to a cousin of Noorhachu, and who at once appealed to Hootooala for assistance. The whole Manchu clan marched to his rescue, and it was on this occasion that Noorhachu had his first experience of war on a large scale. The Manchus presented such a bold front that there is every reason to believe that Haida and his Chinese allies would have failed to conquer Goolo by force, but they resorted to fraud, which proved only too successful. Haida succeeded in enticing the old chief Huen and his son, the father of Noorhachu, into a conference, when he murdered them and many of their companions. The momentary success gained by this breach of faith was heavily paid for by the incentive it gave Noorhachu to exact revenge for the brutal and cowardly murder of his father and grandfather. Haida constructed a fortified camp at Toolun, but he did not feel secure there against the open attacks of Noorhachu or the private plots he formed to gain possession of his person. Several times Haida fled from Toolun to Chinese territory, where he hoped to enjoy greater safety, until at last the Chinese became tired of giving him shelter and protecting one who could not support his own pretensions. Then, with strange inconstancy, they delivered him over into the hands of Noorhachu, who straightway killed him, thus carrying out the first portion of his vow to avenge the massacre at Goolo.
