慕容熙
Around the new year 406, Murong Xi, with Empress Fu with him, was making a surprise attack on Khitan tribes when he decided that the Khitan were too strong to be attacked and wanted to withdraw. However, at Empress Fu's insistence that she wanted to observe a battle, he abandoned his heavy guard and took his faster cavalry to attack Goguryeo. The attack was unsuccessful, and he was forced to withdraw.
