Jiangling County
The forces led by Zhang He immediately used the south side of the Yangtze below Jiangling County and the north banks to build pontoon bridges to cut off supplies from the Wu commander Zhu Ran, whose forces were shut inside the city. Zhu Ran also had to face the task of keeping order within the city. For example, when the city was running low on its water supply, some civilians and soldiers tried to surrender to Wei by opening the gates, but Zhu Ran put an end to the plot.
