succeed in capturing the city, so his officers gave up their idea of attacking and complied with Lu Kang's orders to construct the defensive structures. Destruction of the dyke near Jiangling When Jin forces led by Yang Hu were approaching Jiangling County, the Wu officers advised Lu Kang against leaving Jiangling to attack Xiling, but Lu Kang said: "Jiangling's fortifications are strong and it has sufficient troops to defend it, so there is no need to worry. Even if the enemy captures Jiangling, they won't be able to hold it for long and our losses will be minimal. However, if we lose Xiling, the tribes in the southern hills will be affected and this will lead to serious problems. I'd rather abandon Jiangling than give up on capturing Xiling. Besides, Jiangling is already very well-defended in the first place." Jiangling was situated on flat lands and was a very accessible location. However, Lu Kang later ordered Zhang Xian () to oversee the construction of a large dyke to block the river's flow and direct its waters to flood the flat lands, so as to create a large body of water around the city to serve as a barrier to invaders. When Yang Hu arrived, he planned to make use of this barrier by transporting supplies on boats, but he spread false news that he intended to destroy the dyke to make way for his land army to pass through. When Lu Kang heard that, he saw through Yang Hu's plot and ordered Zhang Xian to destroy the dyke. Lu Kang's officers were shocked and attempted to dissuade him from doing so because they thought he would be doing the enemy a favour, but Lu Kang ignored them. When Yang Hu reached Dangyang (當陽; southwest of present-day Jingmen, Hubei), he was dismayed to hear that the dyke had been destroyed. He had no choice but to transport his supplies on land, resulting in the wasting of time and effort. Final stages Xu Yin (), the commander of the Jin garrison at Badong Commandery (巴東郡; around present-day Fengjie County, Chongqing), led naval forces towards Jianping (建平; around present-day Zigui County, Hubei), while Yang Zhao (), the Inspector of Jing Province (also under Jin control), led troops towards Xiling. Lu Kang gave orders that: Zhang Xian reinforce Jiangling's defences; Sun Zun (), the Commandant of Gong'an County, patrol the south river bank and
