Cao Hong
Chen Wen (陳溫), the Inspector of Yang Province, was on friendly terms with Cao Hong. At the time, Cao Hong had about 1,000 men from his own militia. He asked for troops from Chen Wen, who provided him with 2,000 of his best soldiers. Cao Hong then went to Danyang Commandery (丹楊郡) and managed to recruit about another 1,000 men with help from the commandery's Administrator, Zhou Xin. He brought along his 4,000 troops to meet Cao Cao at Longkang (龍亢; in present-day Huaiyuan County, Anhui) and became one of Cao Cao's most loyal followers since then.
