睢水 / Sui River
睢水 / Sui River enters the wiki through Hanji 151 part 2 as the casualty marker after 项羽 breaks 刘邦’s allied army at the 彭城之战. The source cites the phrase “睢水为之不流” to convey that killed and drowned soldiers filled the river after the pursuit.
The river is not just scenery in this account. It marks how 骑兵奇袭指挥中枢 and pursuit convert battlefield defeat into disaster: once the coalition loses order, pressure toward river terrain turns flight into crowding, trampling, drowning, and slaughter.
Hanji 162-1 adds a later logistics role for the same river zone. After 袁先生 / 袁生 draws 项羽 south toward 宛县 and 刘邦 refuses battle, 彭越 moves around Sui River and cuts Chu supply, turning the river from a Pengcheng casualty marker into a rear-pressure geography.
