Lian Po
In 271 BCE the State of Qin sent a large army to attack Han, but would have to attack the Zhao territory in the way. The Zhao army was no match for the Qin, who captured a large part of the Zhao territory. The Qin forces were approaching E Yu (閼與, in present-day Heshun county (和順縣), Shanxi province), which was very far from the Zhao capital of Handan. At that time the commander-in-chief of the Zhao forces, Lian Po recommended abandoning E Yu as it was too far away to reinforce. Also, the road to E Yu was narrow and winding. Zhao She told the ruler and the commander-in-chief that when two armies were fighting in a narrow and winding road it was like two rats fighting in a little hold with not much room to manoeuvre. The braver and stronger one would win.
