After about a year of uneasy cease fire in Lhasa, the Tibetan people once more rose against the occupying Chinese. On 1 March 1959, the Fourteenth Dalai Lama was invited to attend a Chinese cultural event at a PLA encampment in Lhasa. He was told not to bring any of his bodyguards and keep the arrangements secret. When word leaked of this, the Tibetans assumed that the Chinese were planning to kidnap their leader. Tens of thousands of Tibetans surrounded the Norbulingka to prevent the Dalai Lama from attending. As a consequence the Dalai Lama declined the invitation, to the fury of the Chinese PLA general. Fighting broke out on 16 March 1959, culminating with the shelling of the Norbulingka. The Fourteenth Dalai Lama fled during the night of March 16-17 disguised as a soldier. It took him two weeks to reach India, crossing high passes in the snow, constantly harassed by the pursuing Chinese.
The fighting continued in Lhasa for three days, 20,000 Tibetans armed with antiquated weapons confronting PLA mortars and cannons. At 2:00 am on 20 March, the Chinese began to systematically shell the city, firing from all directions. Many of the most important and sacred structures were targeted, including the Potala, and Drepung and Sera monasteries. The Drepung was damaged, the Sera Monastery almost completely destroyed, and large holes were blasted in the walls of the Potala. Exiles later reported that the streets were littered with bodies. Chinese tanks rolled into Barkhor Square before the Jokhang on 22 March, effectively ending the rebellion.
