徐州屠杀 / Xuzhou Massacre (Late Han)
徐州屠杀 / Xuzhou Massacre (Late Han) enters the wiki through Hanji 971 as the civilian-devastation branch following 曹嵩遇害. After 曹嵩 and 曹德 are killed, 曹操 attacks 陶谦 in 徐州, takes cities, defeats Tao Qian near Pengcheng, and carries retaliation into civilian space.
The episode stresses that Xuzhou is not an empty battlefield. Refugees from the Luoyang and Dong Zhuo disorder have moved into the region, so Cao Cao’s revenge strikes a crowded refuge zone. The cited 《后汉书》 line about killings at the 泗水 is kept as a source-scoped atrocity notice, and the later taking of Qulu, Suiling, and Xiaqiu extends the pattern from river killing to city slaughter.
The event is a key late-Han case for 以国力行私仇 and 民心型政治安全. A real family loss becomes politically and morally catastrophic when a regional commander answers it with campaign capacity, while later Xuzhou strategy pages note that harsh earlier warfare damaged the local people-support environment.
