Hanzhong Campaign
Zhuge Liang might be right about Fa Zheng, as inferred from an incident during the Hanzhong Campaign. During one battle, when the odds turned against Liu Bei, Liu's subjects urged their lord to retreat but he stubbornly refused. They did not dare to advise him again for fear of incurring his wrath. Fa Zheng rushed forth and stood in front of Liu Bei when Cao Cao's forces rained arrows on their camp. Liu Bei told Fa Zheng to stay under cover to avoid the arrows, but Fa insisted on braving the arrows with his lord. Liu Bei then decided to retreat together with Fa Zheng.
