陳泰
When Chen Tai was retreating back to Longxi Commandery, he predicted that Jiang Wei would attempt to make use of the mountainous terrain along the way to lay an ambush, so he took a southern detour back to Longxi. As he expected, Jiang Wei had indeed sent troops to lie in ambush for three days. However, the historian Pei Songzhi pointed out that it made no sense for Jiang Wei to set up the ambush because he did not know that Wei reinforcements would show up when he was besieging Didao so the ambush would not have served its purpose.
