Pang Juan, commander of Wei, was lured to a narrow pass at night, where his army was ambushed by 10,000 crossbowmen from Qi.

Wei was defeated and its power decreased significantly thereafter, making the state unable to compete for hegemony of the Zhou dynasty.

Instead of sending troops to save Han directly, Sun Bin suggested they should aim for the capital of Wei, Daliang.

Pang Juan also ordered his troops to make haste to the capital, before Qi could set up any effective ambushes.

As Qi retreated into their own territory, Sun Bin ordered his troops to abandon some of their heavy artillery.

As Qi arrived at Maling, Sun Bin noticed a heavily wooded and narrow pass that could be used for ambush.

Pang Juan had moved to Malingdao, and when he saw the warning message, he paid no attention, instead ordering the words to be scraped off.
