Stratagem No. 04 第四计 Winning stratagems (胜战计)
Wait at ease for the weary enemy
Literal
With ease, await exhaustion.
Stay fresh, make the other side do the marching, and fight only when their strength has already ebbed.
Source line
困敌之势，不以战；损刚益柔。
Traditional 困敵之勢，不以戰；損剛益柔。
Exhaust the enemy’s situation without giving battle. Decrease the hard and increase the soft.

The second clause echoes the hexagram Sun (Decrease), which speaks of diminishing the hard and benefiting the soft. Here the hard is the enemy’s aggressive strength. You do not break it in a clash. You let time, supply and their own movement wear it down, while your side stays intact.

Meaning
Wait at ease for the weary enemy means refusing battle until the other side has spent the strength you would otherwise have to fight. Ease is not idleness. It is a prepared stillness: positions held, troops fed, information coming in, and no prestige lost by not marching. The enemy’s weariness may come from a long road, a siege, hunger, or the simple strain of staying angry and alert while you do not oblige them with a fight.
The manual’s commentary says the point is wider than choosing a good piece of ground and sitting on it. It is a way of handling change: answer a large disturbance with a small one, and movement with stillness, so that you remain the pivot and they remain the wheel. Sun Tzu already has the narrow military form. The side that reaches the field first and waits is fresh, and the side that hurries up afterwards is worn. This named stratagem belongs to the later list.
The story
Li Mu on the Zhao frontier
History
Li Mu was Zhao’s general on the northern frontier, based in the Dai and Yanmen region against the Xiongnu. The Shiji gives no year. The command belongs to the Warring States, in the third century BC. He had unusual freedom: local taxes went to his headquarters, and he slaughtered cattle daily for the troops, drilled them, kept the beacons strict, and paid his men well. His standing order was severe. If the Xiongnu raided, the people were to withdraw into the defences. Anyone who went out to take captives would be executed.
This lasted several years. Losses stayed small. The Xiongnu decided he was a coward, and so did many of his own border troops. The king rebuked him. He did not change. The king removed him. The replacement fought, and fought at a loss. The frontier could no longer farm or pasture in peace. Li Mu was asked back. He refused until the king agreed that the old order would stand. He then resumed it. Again the raiders got nothing, and again they took the refusal for fear.
When his own men, well paid and unused, were eager for a battle, he changed the sign. Herds were left out in the open. A small Xiongnu probe was allowed a sham defeat. The chanyu came in force. Li Mu had prepared chariots, cavalry and a large body of picked infantry, and he struck with an ambush and both wings. The Shiji says he destroyed more than 100,000 riders, broke the neighbouring tribes, and that the Xiongnu did not approach the Zhao frontier for more than a decade. The number is the historian’s. The method is the stratagem: years of prepared ease, then one fight against an enemy who had learned contempt.
Told in Sima Qian’s Shiji, chapter 81; the victory is undated there, and the figure of more than 100,000 riders is the Shiji’s.

Myth check
The idea of meeting a weary enemy with a fresh one is in Sun Tzu’s Art of War. The four-character name, as one item in the Thirty-Six Stratagems, is not a chapter of that book, and the collection is not by Sun Tzu.
Modern application
A smaller firm facing a larger one often loses the moment it accepts every invitation to compete. Waiting at ease means choosing the one surface you can hold, funding it properly, and letting the other side exhaust itself on launches, discounts and travel. The waiting has to be real preparation. A company that is merely slow, with no stock of skill or cash, is not at ease. It is late.
In a dispute, the party that must have an answer today is already the weary one. Deadlines, public anger and a long journey to the table all spend strength. The defence is to notice when your own side is the one being kept awake. If the delay is costing you more than it costs them, the stratagem is being used on you, and stillness has become the trap rather than the plan.
Takeaways
- Prepare while you wait. Unprepared stillness is only delay.
- Let them spend the march, the anger and the supply.
- Strike once their contempt has replaced their caution.
How to counter it
Do not accept a tempo set by the side that is sitting still. If waiting is hurting you faster than it hurts them, change the clock: a deadline, a new front, or a withdrawal.
Questions
What does wait at ease for the weary enemy mean?
It means refusing battle until the other side has worn itself down, while your own side stays fed, informed and in place. Ease is prepared stillness, not doing nothing. The manual links the idea to decreasing a hard strength without a head-on fight. Li Mu’s long refusal to chase Xiongnu raiders is the classic case.
Is wait at ease for the weary enemy a Sun Tzu quote?
The underlying idea is in the Art of War: the army that takes its place first and waits is fresh, and the army that arrives later is exhausted. The sentence people quote as a free-standing proverb is a paraphrase. The named stratagem belongs to the Thirty-Six Stratagems, a separate and much later text.
