The suddenness of this movement found the Thibetans quite unprepared. Everything gave way before the bold invaders, and in a short time Degarchi, the second town of the state, fell into their hands. This was the residence of the Teshu Lama, ranking next to the Dalai in authority, and possessed the vast lamasary of Teshu Lumbo, rich in accumulated wealth, which fell into the hands of the invaders. A farther advance would undoubtedly have given them the chief city of Lhassa, since the unwarlike population fled in terror before their advance, but their success at Degarchi had been so great as to check their march, many weeks being spent in counting their spoil and subduing the surrounding country. Meanwhile urgent petitions were sent to Peking, and the old emperor, aroused to the necessity for prompt and decisive action, gave orders that all available troops should at once be despatched to Lhassa and vigorous preparations made for war. Within a few months a Chinese army of seventy thousand men, armed with several pieces of light artillery, had reached Thibet, where the Goorkhas, alarmed by the numbers of their opponents, made hasty preparations for a retreat. But their spoil was so abundant and bulky as to delay their march, and the Chinese, who were well commanded, succeeded in coming up with them before they had crossed the mountain passes. The movements of the Chinese commander were so skilfully made that the retreat of the Goorkhas without a battle for the safety of their treasures became impossible. Sund Fo, the Chinese general, according to the usual practice of his people, began by the offer of terms to the enemy, these being the surrender of all their spoil and of a renegade lama whose tale of the wealth of Thibet had led to the invasion. Probably also pledges for better conduct in future were demanded, but the proud chief of the Goorkhas haughtily refused to accept any of these conditions and defied his foes to do their worst. Of the battle that followed nothing is known except its result, which was the defeat and hasty retreat of the invaders, much of whose baggage was left behind. The Chinese do not seem to have suffered greatly, to judge from the promptness of their pursuit, which was made with such rapidity that the Goorkhas were overtaken and again defeated before they had reached the Kirong pass, they being now obliged to abandon most of their baggage and spoil. The pursuit continued with an energy remarkable for a Chinese army, the Goorkhas, bold as they were by nature, growing demoralized under this unlooked-for persistence. Every encounter resulted in a defeat, the forts which commanded the mountain passes and defiles were taken in succession by Sund Fo's army, and he still pressed relentlessly on. At a strong point called Rassoa the Goorkhas defended for three days a passage over a chasm, but they had grown faint-hearted through their successive defeats, and this post too fell into the hands of their enemy.
