Zhuge Zhan
The aforementioned military movements happened within weeks, and Zhong Hui's rapid advance shocked most of the Shu generals. As they realised the danger of letting the enemy in, Jiang Wei and his comrades were still stuck at Jiange. As he knew that Jiange was well-defended, Zhuge Zhan did not send reinforcements there and instead held his position in Fu County. When the Wei general Deng Ai suddenly appeared in Jiangyou (江由) with his troops after taking a dangerous shortcut across mountainous terrain, the official in charge of Jiangyou surrendered without putting up a fight. Huang Chong, a son of Huang Quan, had urged Zhuge Zhan on numerous occasions to move quickly and seize control of advantageous terrain before Deng Ai did. Zhuge Zhan, however, deemed Huang Chong's plan too ambitious and adopted a more "cautious" approach instead. When Huang Chong repeatedly urged him to attack Deng Ai, Zhuge Zhan relented and tentatively sent a vanguard force to attack the enemy, which defeated them. Zhuge Zhan then left Fu County for the better fortified Mianzhu, where he planned to make a last stand against Deng Ai.
