Battle of Yan Ford
battle between warlords Yuan Shao and Cao Cao (200)
The Battle of Yan Ford took place along the southern banks of the Yellow River in the late Eastern Han dynasty. The battle was closely preceded by the Battle of Boma, and was part of a series of engagements leading to the decisive confrontation between the rival warlords Yuan Shao and Cao Cao at the Battle of Guandu in 200. Following the death of one of Yuan Shao's elite generals, Yan Liang, in the previous battle, the death of another famed general Wen Chou in this battle greatly demoralised Yuan's army, which was heading towards Guandu.
Background
Cao Cao and Yuan Shao were heading toward a direct confrontation since the late 190s, and the first months of 200 saw the opening of hostilities at the Battle of Boma after years of manoeuvring. With a feint, Cao Cao was able to split off Yuan Shao's main force gathered at Liyang (黎陽; northwest of present-day Xun County, Henan) across the river from Boma (白馬; near present-day Hua County, Henan) and hence relieve the siege at Boma, killing Yuan Shao's attacking general Yan Liang. Considering that the position at Boma was unsuitable for a determined defence, Cao Cao voluntarily abandoned the outpost and evacuated its population and supplies to the west along the river. With that, Yuan Shao finally crossed the Yellow River in pursuit of Cao Cao's baggage train. However, Cao Cao was not satisfied with just abandoning all lands between Guandu and the river to the enemy — he had also wanted to make his enemy pay dearly by resisting the enemy advance during the predetermined fallback to Guandu.
The battle
As a result of Cao Cao's feint during the Battle of Boma, Yuan Shao had brought the advance-guard of his army up the Yellow River toward the western Yan Ford (延津; north of present-day Yanjin, Henan). It was probably at this ford that Yuan Shao's army made the crossing, which was unhindered by Cao Cao.

Why this record matters
The phrase “battle between warlords Yuan Shao and Cao Cao (200)” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Contemporary correspondence, administrative files and participant testimony can test how later narratives organized the event or institution. The source revision retrieved here is dated Aug 22, 2026. The linked authority identifier is Q4872766. None of the 0 selected statements returned an explicit reference.
Institutional narratives can privilege the records that survived while minimizing voices that were never formally collected. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
