兖州 / Yanzhou (Late Han)

Hanji 961 adds the pre-Cao pressure field before Yanzhou becomes Cao Cao’s root base. 刘岱 is caught between 袁绍 and 公孙瓒, with 范方’s cavalry support turning into coercive leverage over Yuan Shao’s household.

The same source also makes nearby 东郡 part of Cao Cao’s early Yanzhou-adjacent rise. 曹操 is already stationed at 顿丘 when 于毒 attacks 东武阳, and the resulting 内黄之战 helps him consolidate the military reputation and local command capacity that Hanji 964 will later move into Yanzhou proper.

Hanji 964 adds the first Yanzhou succession crisis before the later Cao Cao-Lü Bu base struggle. 刘岱 rejects 鲍信’s defensive attrition plan against the 青州黄巾军 and dies in a field battle. 鲍信, 万潜, and the transcript’s “成公” persuasion channel then help bring 曹操 into the province.

The source makes Yanzhou’s early value visible before it becomes Cao Cao’s mature root base. The province is gained through local crisis invitation and hard fighting rather than simple appointment: the court names 金尚, while Cao Cao blocks him and holds the practical position that later pages treat as 根本根据地优先.

Hanji 973 supplies the immediate military trigger before the causal explanation in Hanji 974 and the warning scene in Hanji 975. While 曹操 is attacking 陶谦 in 徐州, 张邈 and 陈宫 invite 吕布 into Yanzhou.

The source’s key Yanzhou fact is the speed of base collapse. Cao Cao has to abandon Xuzhou and return because only 鄄城, 范县, and 东阿 remain on his side, setting up the later Xun Yu and Cheng Yu base-preservation episodes.

Hanji 974 adds the political prelude to Yanzhou’s military collapse. Before 荀彧 detects the rebellion in Hanji 975, the source says 曹操’s relationship with local elites has already been damaged by 边让’s killing and by fear that criticism or resistance could become fatal.

In this reading, Yanzhou is not only a base of cities and grain. It is also a coalition with local elite confidence. 张邈 and 陈宫 move toward 吕布 after combining 袁绍 pressure, Zhang Miao’s own 陈留 base, and 地方士族安全恐慌 into a preemptive betrayal.

Hanji 975 supplies the trigger layer before the later remaining-city defense. While 曹操 is attacking 陶谦 in 徐州, 张邈 and 陈宫 welcome 吕布 as Yanzhou governor, and 荀彧 identifies the danger from envoy wording, Lü Bu’s route, and the exposed rear.

The source makes Yanzhou’s crisis visible before a battle. 夏侯惇 is recalled from 濮阳 to hold 鄄城, while Puyang is then exposed to Lü Bu. This turns the province into an early 细节式危机识别 and 根本根据地优先 case: survival begins with noticing that the rear has shifted before the main force can return.

Hanji 978 adds the immediate morale-and-county layer before the Hanji 979 base-preservation mechanics. With most of Yanzhou defecting toward 吕布 and 张邈, the source names 鄄城, 范县, and 东阿 as the remaining Cao-side strongholds. 荀彧 deters 郭贡 at Juancheng, then sends 程昱 east, where 靳允 kills 范仪 and keeps Fan County.

Hanji 979 adds the immediate base-preservation layer before Hanji 980’s Puyang trap. With much of Yanzhou turned away from 曹操, 程昱 blocks 陈宫 at 仓亭津 and 枣祗 organizes 东阿, preserving the remaining cities Cao Cao needs as a home base.

The same source makes Yanzhou a strategic reading test for 吕布. Cao Cao argues that Lü Bu would have been dangerous if he had taken 鄄城 and cut the grain route, so Yanzhou’s value lies in cities, crossings, route control, harvest, and people organization together.

Hanji 980 adds an earlier Puyang crisis to the Yanzhou branch. 濮阳田氏 draw 曹操 into 濮阳, 吕布 presses him into a near-fatal city fight, and 典韦 helps him escape. The province is therefore already a contested base before the later adviser-centered root-base discussion in Hanji 987.

The same source makes Yanzhou’s campaign outcome material rather than only tactical. After further fighting around 濮阳之战 lasts more than a hundred days, locust damage and grain exhaustion force withdrawal, and Lü Bu’s failed attack on 乘氏县 against 李进 shows local resistance joining food pressure.

Hanji 986 adds the compact recovery stage before the Dingtao-focused page. 曹操 kills 吕布’s Juye commanders 薛兰 and 李封, defeats Lü Bu’s rescue force by ambush, and recovers much of Yanzhou before being tempted by the news from 徐州.

兖州 / Yanzhou (Late Han) enters the wiki through Hanji 987 as 曹操’s contested root base. 荀彧 argues that Cao Cao should not leave the province to pursue 徐州 while 吕布, 张邈, and their allies still threaten the rear. In the episode’s analogy, Yanzhou is to Cao Cao what 关中 is to Liu Bang and 河内 is to Liu Xiu: the base that makes both attack and defense possible.

The source makes Yanzhou a material as well as symbolic base. Its wheat harvest, people-support, city defense, and road security decide whether Cao Cao can sustain any later offensive. If he abandons it too soon, he may keep only a few strongholds while losing the province that made his army and authority operational.

Hanji 989 gives the closing turn of the same branch. Cao Cao surrounds 雍丘, Zhang Miao tries to flee toward 袁术, and 刘翊 kills him before that exit can strengthen an enemy camp. The episode then reports Cao Cao’s appointment as Yanzhou governor, making the province a formal as well as battlefield base.

The later Zang Hong branch keeps Yanzhou’s aftershocks visible. Hanji 996 remembers that Zhang Miao had welcomed Lü Bu into Yanzhou against Cao Cao, which helps explain why Cao Cao will not spare 张超 at Yongqiu. Hanji 1000 later makes the Yanzhou gentry channel part of 陈宫’s protected position inside Lü Bu’s camp.
