Xiao He
In 196 BC, while Gaozu was away on a military campaign to suppress a rebellion by Chen Xi, one of Han Xin's servants reported to Empress Lü Zhi that his master was involved in a conspiracy with Chen Xi and was planning a coup in Chang'an. Empress Lü approached Xiao He for help and they formulated a plan to lure Han Xin into a trap. Xiao He had an imperial edict sent to Han Xin, announcing news of Gaozu's victory over Chen Xi, asking Han to meet the emperor and offer his congratulations. As soon as Han Xin arrived in Changle Palace, he was arrested and executed in a torturous manner for alleged treason.
