《智囊(选录)·胆智部·杨素》
到对阵作战时，杨素先派一二百名士兵与敌交战，凡是不能尽力冲锋陷阵苟且生还者，一律予以处死。
又对阵时，先令一二百人赴敌，或不能陷阵而还者，悉斩之。
When it was time for opposing armies to fight, Yang Su would first send out 100 or 200 soldiers to fight the enemy. Anyone who did not charge into the battle with full force and survived would be put to death without exception.
