《资治通鉴·汉纪·汉纪二十一》
西域都护甘延寿，副校尉陈汤，秉承圣上旨意，倚仗神灵，统率百蛮的君主，集结各城邦的军队，百死一生，深入极远的地域，于是击破康居，攻杀郅支单于的三层城防。拔掉歙侯大旗，砍下郅支单于人头，悬挂战旗于万里之外，为国家扬威到昆仑山之西。洗刷掉谷吉被杀的耻辱，建立了光辉的功勋，所有的夷民全都慑服，无不震恐。
西域都护延寿，副校尉汤，承圣指，倚神灵，总百蛮之君，揽城郭之兵，出百死，入绝域，遂蹈康居，屠三重城，搴歙侯之旗，斩郅支之首，县旌万里之外，扬威昆山之西，扫谷吉之耻，立昭明之功，万夷慑伏，莫不惧震。
In accordance with the holy wishes, Protector-General of the Western Regions Gan Yanshou and Deputy Commandant Chen Tang, relying on divine favor, commanded the kings of the hundreds of barbarian tribes and assembled the armies of the various city states. Facing a life-or-death situation and penetrating extremely remote regions, they inflicted a crushing defeat on Kangju, captured and killed Zhizhi Chanyu in his triple-layered city defences, seized the great banner of Xihehou, cut off the head of Zhizhi Chanyu, and planted the battle flag tens of thousands of li away, extending the might of our country west of Mount Kunlun. They washed away the shame of Gu Ji’s murder and achieved glorious feats in battle. All the barbarians were subjugated and terrified.
