Article: General-in-Chief He Jin (d. 189 AD), half-brother to Empress He (d. 189 AD), plotted with Yuan Shao (d. 202 AD) to overthrow the eunuchs by having several generals march to the outskirts of the capital. There, in a written petition to Empress He, they demanded the eunuchs' execution. After a period of hesitation, Empress He consented. When the eunuchs discovered this, however, they had her brother He Miao () rescind the order. The eunuchs assassinated He Jin on September 22, 189 AD. Yuan Shao then besieged Luoyang's Northern Palace while his brother Yuan Shu (d. 199 AD) besieged the Southern Palace. On September 25 both palaces were breached and approximately two thousand eunuchs were killed. Zhang Rang had previously fled with Emperor Shao (r. 189 AD) and his brother Liu Xiethe future Emperor Xian of Han (r. 189220 AD). While being pursued by the Yuan brothers, Zhang committed suicide by jumping into the Yellow River.
