沔口 / Mian Kou (late Han)

Overview

沔口 / Mian Kou is the river-confluence position in Hanji 1085 where 黄祖 attempts to block 孙权’s westward advance into 江夏郡.

Current Profile

The episode places Mian Kou at the Han River’s entry into the Yangtze and treats it as the operational lock on Jiangxia. Huang Zu anchors two mengchong warships across the approach, but 董袭 and 凌统 lead the assault that breaks the fixed barrier. The case makes Mian Kou a concrete expression of 长江走廊战略根据地: control of a narrow river junction can determine whether a larger army can move through the corridor.

Key Characteristics

• Presented as the Han-Yangtze confluence and core approach to Jiangxia.
• Functions as a westward movement chokepoint for Wu.
• Is defended through anchored warships, protective covering, and concentrated archery.
• Falls open when the mooring cables are cut, allowing the main force to advance.

Evidence

• Geographic role: Hanji 1085 identifies Mian Kou as the Han River’s entry into the Yangtze and the key local node.
• Defensive use: Hanji 1085 says Huang Zu blocks the approach with anchored mengchong warships and massed archery.
• Barrier breach: Hanji 1085 credits Dong Xi’s cutting of the moorings with opening the route to Sun Quan’s main force.
