耿武 / Geng Wu (late Han)
Hanji 956 introduces Geng Wu as one of 韩馥’s subordinates who argues against yielding 冀州 to 袁绍. He reads the material balance differently from Han Fu: Jizhou has troops and long grain supply, while Yuan Shao is hungry, scattered, and dependent.
Geng Wu’s warning becomes a negative-feedback case. The advice is not absent; Han Fu hears it and rejects it because fear and self-abasement have already made surrender look like virtue. When Yuan Shao enters 邺城, Geng Wu and 闵纯 attempt armed resistance and are killed.
