《明史·列传·卷一百五十》
其他贼兵开向北面去进犯延安，传庭知道州以西、合水以东的三四百里都是荒山深谷，贼兵进去就会自取灭亡，于是亲率标兵从中部阻止贼兵向东跑，传令变蛟在庆阳阻止贼兵向西逃，在三水、淳化之间设下了埋伏。
贼引而北，犯延安。传庭策鄜州西、合水东三四百里，荒山邃谷，贼入当自毙，乃率标兵中部遏其东，檄变蛟、庆阳拒其西，伏兵三水、淳化间。
The rest of the rebel army went north to attack Yan'an. Chanting knew that 300 or 400 li west of the prefecture and east of Heshuo were deserted mountains and deep valleys. If the rebel army went in, they would be destroying themselves, so he personally led the soldiers to stop the rebel army from running east from the center and ordered Bianjiao to stop them from escaping west in Qingyang and set an ambush between Sanshui and Chunhua.
