Peking as Chief of the General Staff--an appointment which would place him under direct surveillance. First on one excuse, then on another, General Feng Kuo-chang had managed to delay his departure from day to day without actually coming under the grave charge of refusing to obey orders. But finally the position was such that he telegraphed to General Tsao-ao that unless the Yunnan arrangements were hastened he would have to leave Nanking--and abandon this important centre to one of Yuan Shih-kai's own henchmen--which meant the end of all hopes of the Yangtsze Valley rising _en masse_. It was to save Feng Kuo-chang, then, that the young patriot Tsao-ao caused the ultimatum to be dispatched fourteen days too soon, _i.e._, before the Yunnan troops had marched over the mountain-barrier into the neighbouring province of Szechuan and seized the city of Chungking--which would have barred the advance of the Northern troops permanently as the river defiles even when lightly defended are impassable here to the strongest force. It was largely due to the hardships of forced marches conducted over these rugged mountains, which raise their precipitous peaks to the heavens, that Tsao-ao subsequently lost his life, his health being undermined by exposure, tuberculosis finally claiming him. But one thing at least did his resolute action secure. With Yunnan in open revolt and several other provinces about to follow suit, General Feng Kuo-chang was able to telegraph Peking that it was impossible for him to leave his post at Nanking without rebellion breaking out. This veiled threat was understood by Yuan Shih-kai. Grimly he accepted the checkmate. Yet all the while he was acting with his customary energy. Troops were dispatched towards Szechuan in great numbers, being tracked up the rapids of the upper river on board fleets of junks which were ruthlessly commandeered. Now commenced an extraordinary race between the Yunnan mountaineers and the Northern plainsmen for the strategic city of Chungking. For some weeks the result was in doubt; for although Szechuan province was held by Northern garrisons, they were relatively speaking weak and surrounded by hostile Szechuan troops whose politics were doubtful. In the end, however, Yuan Shih-kai's men reached their goal first and Chungking was saved. Heavy and continuous mountain-fighting ensued, in which the Southern troops were only partially successful. Being less well-equipped in mountain artillery and less well-found in general supplies they were forced to rely largely on guerrilla warfare. There is little accurate record of the desperate fighting which occurred in this wild region but it is known that the original Yunnan force was nearly annihilated, and that of the remnant numbers perished from disease and exposure.
