《资治通鉴·汉纪·汉纪三十八》
马防等人的部队到达冀县时，布桥正率羌军在临洮围攻南部都尉。马防发动进攻，打败了布桥，斩杀、俘虏四千余人，于是临洮解围。羌军全部投降，只剩下布桥等二万余人，盘踞在望曲谷，未被攻克。
马防等军到冀，布桥等围南部都尉于临洮，防进击，破之，斩首虏四千馀人，遂解临洮围；其众皆降，唯布桥等二万馀人屯望曲谷不下。
When Ma Fang and others' troops arrived at Jixian, Bu Qiao was leading the Qiang army in besieging Southern Duwei in Lintao. Ma Fang launched an attack, defeated Bu Qiao, and killed or captured more than 4,000 people, so Lintao was relieved. The Qiang army surrendered as a whole, leaving only more than 20,000 people such as Bu Qiao, who occupied the Wangqu Valley and were not conquered.
