1759 he recovered all the cities which had been seised by the Sungar rebels. By his advice the New Dominion was occupied by soldiers, a chain of posts established, and cities built at Urumtsi and other places, the Emperor standing in great fear of Russian encroachments. In 1761, when his portrait had been enshrined as the seyenteenth among the heroes of the conquest of Turkestan , he was appointed President of the Board of Works and Military Governor of Hi. After serying in Ssdch^uan against the Ush tribes, he was sent in 1768 to check a Burmese irruption. Beaching Momein in Noyember, he advanced early next year; and afker defeating a Burmese flotilla laid siege to Eaungtdn. This place o£fered a long resistance, and 0-kuei was on the point of with- drawing his army, decimated by pestilence, when the Burmese accepted a treaty and promised tribute and a cession of territory. In 1770 he was sent to Momein to receive the tribute; but it was not forthcoming, and the Burmese kept his messenger a prisoner. He suggested letting the matter stand over, for which he was cashiered in 1771 but was allowed to serye under the new general. Soon after this he was sent again to Chin-ch'uan, and in 1772 succeeded to the command, on the defeat of the Imperial forces. For the next two years he was cam*paigning on the Sstich^uan frontier, and for yarious successes was ennobled as Duke and appointed to be President of the Board of Reyenue, being received by the Emperor with extraordinary honours. The Burmese envoys baying at length arrived, they were taken to the execution-ground, but were sent home again under escort; and next year 0-kuei went

back to Yiinnan, and a Burmese decennial tribute was agreed upon. For this he was made a Grand Secretary; and then followed various important missions to the Yellow Riyer, to inspect the sea-wall at Hangchow, and to put down revolts in Sj;knsuh. From 1787 to 1792 he was again in the west, engaged in putting down rebellion.
