The Battle of Rangcheng (or Anzhong) in 198 AD stands not merely as a military engagement between Cao Cao and Zhang Xiu, but as a profound case study in strategy, psychology, and leadership.
The year 198 AD saw Cao Cao return to Nanyang Commandery for a second campaign against Zhang Xiu, a conflict defined not by a decisive siege, but by strategic maneuvering, near-disaster, and brilliant counterattacks.
