Luo Xian
In the meantime, Wu prepared to take advantage of the situation to invade Shu and seize control of former Shu territories under the pretext of sending reinforcements to help Shu resist the Wei invaders. Around March 264, the Wu general Bu Xie led troops from Xiling (西陵; present-day Yichang, Hubei) to attack Yong'an but encountered strong resistance from Luo Xian and his men. As the Wu forces rained arrows on his position, Luo Xian ordered his subordinate Yang Zong (楊宗) to break out of the siege and seek help from Wei. He also surrendered his tallies and sent his son as a hostage to convince the Wei regent Sima Zhao of his sincerity. During this time, he led his men to strike back at the Wu forces and defeated them.
