Juyong Pass
In April 1644, the army of the rebel Li Zicheng were approaching the capital through Juyong Pass. On 23 April, the Chongzhen Emperor held his last audience with his ministers. Li Zicheng offered Chongzhen the opportunity to surrender, but the emperor refused. The following day, the rebel army attacked the capital. The Chongzhen Emperor ordered the crown prince and his two brothers to hide in the home of relatives, and summoned the rest of his family. Rather than let them be captured by the rebels, the emperor started killing the female members of his family, concubines and consorts. Using his sword, he killed Consort Yuan and Princess Kunyi, and severed the arm of Princess Changping.
