延岑 / 严岑 / 颜岑 / Yan Cen

Overview

Yan Cen is the Shu-aligned commander rendered as 延岑 in Hanji 686, Hanji 690, and Hanji 711, 严岑 in Hanji 712, and 颜岑 in Hanji 713. Hanji 686 now supplies the earliest current Hanzhong/Wudu layer: Yan Cen rebels, defeats 汉中王刘嘉, occupies 汉中, pushes toward 武都, and later loses to Liu Jia after passing through the Sanguan route. Later notes carry him through Shunyang, Gongsun Shu’s high-title patronage, Fu River defeat, Chengdu counterattack, surrender, and post-surrender clan destruction.

Current Profile

Hanji 686 gives the earliest current layer. Yan Cen rebels and surrounds 南郑, causing Liu Jia to lose and flee. He then occupies Hanzhong and attacks Wudu, before being defeated by Li Bao and withdrawing toward Tianshui. The same source later has Liu Jia fight him again and defeat him after he enters the Sanguan route. This source shows Yan Cen as a mobile early threat before he is fully folded into the Shu-aligned profile.

Hanji 690 continues the Hanzhong-Shu incorporation line. Yan Cen attacks Shunyang, is defeated by Deng Yu, flees to Hanzhong, and receives high office from Gongsun Shu as Da Sima and Runing Wang. That episode makes him part of Shu’s broader effort to absorb displaced anti-Han military capacity before the later Chengdu sequence.

In Hanji 711, Yan Cen appears as 延岑 on the Fu River against Zang Gong. Zang Gong’s force is strained by fleeing surrendered troops and watching counties, but he uses renewed supplies, urgent authority, night movement, flags, and drums to press the attack. Yan Cen is defeated, flees to Chengdu, and his army surrenders.

In Hanji 712, Yan Cen appears before the surrender episode as Gongsun Shu’s last aggressive military adviser. When asked for a plan after prolonged siege pressure, he says there is no alternative to battle. Gongsun Shu gives treasure to recruit a dare-to-die force under him, and Yan Cen then uses flags and drums at the Chengdu bridge/market front while sending cavalry around to strike Wu Han from behind.

In Hanji 713, Yan Cen appears as Gongsun Shu’s battlefield subordinate, sent against Zhang Gong while Gongsun Shu attacks Wu Han. After Gongsun Shu is fatally wounded and entrusts the army to him, Yan Cen offers Chengdu in surrender the next day. Wu Han then destroys Yan Cen’s clan despite the surrender, turning his final role into a breach-of-surrender case.

Key Characteristics

• Early Hanzhong/Wudu threat who defeats Liu Jia before later losing to him.
• Shu-aligned military commander whose name appears as 延岑/严岑/颜岑 across the current source notes.
• Early Hanzhong-Shu incorporation actor: defeated by Deng Yu at Shunyang, then elevated by Gongsun Shu.
• Fu River commander defeated by Zang Gong before fleeing to Chengdu.
• Fight-only adviser who pushes continued battle when Gongsun Shu asks for a way out.
• Surrender broker who offers Chengdu after Gongsun Shu’s mortal wound.
• Victim of post-surrender collective punishment through Wu Han’s destruction of his clan.

Evidence

• Hanzhong-Wudu opening: Hanji 686 says Yan Cen surrounds Nanzheng, defeats Liu Jia, occupies Hanzhong, and attacks Wudu.
• Early reversals: Hanji 686 says Li Bao defeats Yan Cen and that Liu Jia later defeats him near the Sanguan route.
• Shu incorporation: Hanji 690 says Yan Cen attacks Shunyang, loses to Deng Yu, flees to Hanzhong, and receives high titles from Gongsun Shu.
• Name and role continuity: Hanji 711 writes the name as 延岑 on the Fu River before Chengdu, Hanji 712 writes 严岑 in a final Shu-command setting, and Hanji 713 writes 颜岑 in the same Chengdu endgame context.
• Fu River defeat: Hanji 711 says Zang Gong defeats Yan Cen after night movement and flag/drum pressure, causing Yan Cen to flee to Chengdu and the remaining army to surrender.
• Last-fight advice and counterattack: Hanji 712 says Yan Cen tells Gongsun Shu there is no plan except fighting and then uses visible flags, drums, and rear cavalry to defeat Wu Han.
• Battlefield role and surrender: Hanji 713 says Gongsun Shu sends Yan Cen against Zhang Gong, entrusts troops to him before death, and that Yan Cen offers Chengdu the next day.
• Post-surrender punishment: Hanji 713 reports Wu Han destroys Yan Cen’s clan despite the city’s surrender.

Qualifications

The page treats 延岑, 严岑, and 颜岑 as one figure because the role, regime, and sequence align across the source notes. Hanji 686 and Hanji 690 are earlier than the Fu River and Chengdu events, so the Hanzhong/Wudu and Shunyang layers should not be collapsed into the later battlefield outcomes. Hanji 686 leaves Li Bao, Hou Dan, Hechi, and Sanguan source-scoped. If later source notes establish a separate person or a corrected canonical spelling, this page should be reconciled rather than duplicated.

What Changed

• Added Hanji 686 as the earliest current layer: Nanzheng pressure, Hanzhong occupation, Wudu attack, and later defeat by Liu Jia.
• Reframed Hanji 690 as continuation into Shu incorporation rather than the first current appearance.
• Preserved Hanji 711 as Yan Cen’s Fu River defeat by Zang Gong before the Chengdu endgame.
• Preserved Hanji 712 and Hanji 713 as the fight-only advice, counterattack, surrender, and post-surrender clan-destruction layers.
