漢代歷史人物

漢十一年，陳豨反。上自將往，信病不從。乃謀與家臣夜詐詔赦諸官徒奴，欲發以襲呂后、太子。其舍人得罪於信，信囚，欲殺之，舍人弟告信反狀於呂后，呂后乃與蕭相國謀，詐舍人從上所來，言豨已得死，群臣皆賀。信入賀，呂后使武士縛信，斬之。夷三族。

Demotion and death
After Liu became Emperor, he began to become suspicious of the powerful princes -- all of whom were considered a threat to the Han empire -- and found excuses to have them removed, Han Xin not exempted. In winter 202 BC, under the guise of an imperial gathering at Chenqiu (陳丘, in modern Zhoukou, Henan), Han was summoned to a meeting and captured, stripped of his principality, and demoted to Marquess of Huaiyin with no military authority.

In 198 BC or 197 BC, Liu commissioned Chen Xi (陳豨), the Marquess of Yangxia, a friend of Han, to be the commander of the northern border forces to defend the empire against Xiongnu. Once Chen reached the borders, however, he rebelled. Liu left the capital to lead an expedition force against Chen. While he was away from the capital Chang'an in 196 BC, Empress Lü heard rumors that Han was involved in Chen's conspiracy and was ready to raise a rebellion against her. Lü acted preemptively and had Han executed, along with close relatives of his father, his mother, and his wife.

項羽死後，劉邦迅速奪取韓信的兵權，並改齊王為楚王，移都下邳。

逃亡部將鍾離眛素與韓信交好，韓信便將其收留藏匿。劉邦得知鍾離眛逃到楚國後，要求韓信追捕，韓信則派兵保護鍾離眛的出入。前201年，有人告發楚王謀反，漢高祖劉邦採用陳平計策，以出遊為由偷襲韓信。韓信有意發兵抵抗，自陳無罪，但又怕事情鬧大，鍾離眛則自行割頸自殺。韓信帶著人頭於陳（今河南淮陽）向劉邦說明原委，劉邦令人將其擒拿，韓信大喊「果若人言，狡兔死，狗肉亨；高鳥盡，良弓藏；敵國破，謀臣亡。天下已定，我固當亨！」。後來劉邦赦免韓信，降為淮陰侯。

韓信知劉邦害怕自己的才能，常稱病不出，長期怨恨不滿。當陳豨升官至鉅鹿臨走前，韓信與陳豨約定，陳豨若起兵造反，韓信將助一臂之力。漢十年，陳豨果真反叛，韓信便與家臣密謀從內部襲擊呂后、太子等人，但遭親人告密而走漏風聲。呂后與肅何密謀，偽報陳豨已死，引韓信前來祝賀；韓信被束縛後，被斬於長樂宮鍾室，並誅連三族。

劉邦平定陳豨返回之後，得知韓信已死，問韓信死前說了什麼，呂后回答韓信後悔當初不聽蒯通之計。於是劉邦下令捕捉蒯通，蒯通辯稱「當時只知韓信，不知陛下」而被赦免。

傳說中，高祖允諾只要韓信「頂天立地」於大漢，絕不以「兵器」殺之。故韓信被殺時，是吊於鐘樓大鐘下，頭為大鐘所罩，腳懸空於地面，無法頂天立地，並使用竹刀，一說是用桃木劍殺之，以合乎當年的「承諾」。

司馬遷對此評價為：「……假令韓信學道謙讓，不伐己功，不矜其能，則庶幾哉，於漢家勳可以比周、召、太公之徒，後世血食矣。不務出此，而天下已集，乃謀畔逆，夷滅宗族，不亦宜乎！」
