《宋史·列传·卷一百七十一》
如果先攻破离金寨，那么王子山寨也可攻破，岵山、沙窝二寨孤立，三帅可以擒获了。 孟珙第二天派兵奔向离金寨，卢秀拿着黑旗率众入寨，金人没想到是宋军，宋军就分别占领各条巷道，大声喊着放起火来，把寨中金人几乎全部杀死。
若先破离金砦，则王子山砦亦破，岵山、沙窝孤立，三帅成禽矣。 珙翼日遣兵向离金，庐秀执黑旗帅众入砦，金人不疑为宋军，乃分据巷道，大呼纵火，掩杀几尽。
If we first breach Lijin Fortress, then Wangzi Fortress can also be breached. Cishan and Shawo Fortresses are isolated, and the three commanders can be captured. Meng Gong sent troops to attack Lijin Fortress the next day. Lu Xiu led the crowd into the fortress with a black flag. The Jurchens did not expect it to be the Song army, so the Song army occupied all the streets and shouted loudly to set fire to it, killing almost all the Jurchens in the fortress.
