Yong-le: Year 4, Month 9, Day 16
27 Oct 1406
Imperial orders were sent to the Cheng-guo Duke Zhu Neng, regional commander of the force being sent on expedition to punish Annam. The orders read: "The military matters are set and the previous orders have all been acted upon. You should examine the situation carefully and then proceed. When you meet the enemy, if they resist you with weapons, kill them without leniency. However, those who submit, those who receive you and those who run away to hide, are not to be killed. In this way, you will manifest my love for mankind."
