顿丘 / Dunqiu (Late Han)

顿丘 / Dunqiu (Late Han) enters the wiki through Hanji 961 as 曹操’s station when 于毒 attacks 东武阳. The source uses the place as the starting point for Cao Cao’s decision not to rush to the besieged city.

From Dunqiu, Cao Cao chooses a westward mountain movement toward Yu Du’s base. That makes the place part of the operational geometry behind 内黄之战: the campaign begins with a station, a threatened city, and a target shift rather than with a direct city-relief march.
