Battle of Guandu
In the latter stages of the Battle of Guandu, Chunyu Qiong led more than 10,000 troops to Wuchao (烏巢), about 40 "li" north of Yuan Shao's main camp, to receive a new shipment of grain supplies. In early dawn, he was surprised by a raid led by Cao Cao himself. Yuan Shao's cavalry were routed, Wuchao was captured, and Chunyu Qiong was beheaded after the battle.
