Life

Zhuge Xu was from Yangdu County, Langya Commandery (琅邪郡), which is in present-day Yinan County, Shandong. He was probably a distant relative of other famous Zhuges in the Three Kingdoms period, such as Zhuge Jin, Zhuge Liang and Zhuge Dan, since he shared the same ancestral home as them. He served in the state of Cao Wei in the Three Kingdoms period.

In 255, when the Wei generals Guanqiu Jian and Wen Qin started a rebellion in Shouchun (壽春; present-day Shou County, Anhui), Zhuge Xu was then serving as the Administrator (太守) of Taishan Commandery (泰山郡; around present-day Tai'an, Shandong). He led troops from Taishan Commandery to assist other Wei imperial forces led by the regent Sima Shi to suppress the rebellion.

Zhuge Xu was later promoted to the position of Inspector (刺史) of Yong Province in an unknown year. In 263, he participated in the campaign against one of Wei's rival states, Shu. His mission was to lead 30,000 troops to block the Shu general Jiang Wei at a bridge in Yinping (陰平) and stop him from reinforcing Yang'an Pass. When Jiang Wei heard about it, he pretended to launch an attack on Yong Province via Konghan Valley (孔函谷). Zhuge Xu fell for the ruse, thought that Jiang Wei wanted to attack his base, so he ordered his troops to retreat from Yinping by 30 li. Jiang Wei then seized the opportunity to cross the bridge at Yinping. When Zhuge Xu found out and tried to stop Jiang Wei, he was already one day behind time. Later, the Wei general Zhong Hui advanced south from Yang'an Pass and reached Baishui (白水). At the time, another Wei general Deng Ai wanted to link up with Zhuge Xu and attack the enemy position at Jiangyou (江油) together, but Zhuge Xu refused and moved to Baishui to join Zhong Hui instead. At Baishui, Zhong Hui accused Zhuge Xu of cowardice, seized command of his troops and sent him as a prisoner back to Yong Province.

Zhuge Xu later served in the Jin dynasty (266–420), which replaced the Cao Wei state in 265 after the regent Sima Yan usurped the throne from the last Wei emperor Cao Huan. He served as Minister of Ceremonies (太常) and Minister of the Guards (衛尉) under the Jin government.

生平

毌丘儉叛亂時，以泰山太守的身份與其軍交戰。（毌丘儉之亂）

後任雍州刺史，在263年魏滅蜀之戰時統兵三萬，任務是在陰平橋頭攔截蜀將姜維，使姜維無法救援陽安關。姜維且戰且走擺脫鄧艾，聽說諸葛緒已經屯駐在陰平橋，便從孔函谷往北道行軍，作出要偷襲雍州的樣子。諸葛緒聞訊，退軍三十里，而姜維走了三十多里，得知諸葛緒向北移動，立刻掉頭回軍，搶過陰平橋。諸葛緒趕忙追擊，卻慢了一日。接著鍾會得到陽安關並南下，當時在陰平的鄧艾本來想和諸葛緒一起進入江油，諸葛緒以西行非原本所受的詔命，於是引兵到白水找鍾會。鍾會以畏敵不前的名義，將他關進囚車送回本土，將他的軍隊收歸己用。

《三國演義》追加說鍾會打算判其死刑，後由於衛瓘等人的勸阻，遂留交給司馬昭處分。

晉朝成立後，諸葛緒從魏太常官拜崇化衛尉，後封樂安亭侯。
