Sun Tzu said: He who first occupies the battlefield and waits for the enemy is rested. He who arrives later and hurries into battle is worn out.
Thus the skilled fighter controls the enemy and is not controlled by him. To make the enemy come of his own will, lure him with gains. To stop the enemy from approaching, block his way with threats and obstacles.
If the enemy is well-rested, exhaust him. If he is well-supplied with grain, starve him. If he stays secure, force him to move.

A great military strategist and thinker in ancient China, who lived in the late Spring and Autumn Period. He authored The Art of War, the world’s earliest and most influential military classic. His strategic thoughts have been widely applied in military, politics and management worldwide.
Take control of the enemy
The core idea, meaning holding the initiative on the battlefield.
Rest and fatigue
Two opposite states of troops, determined by who seizes the position first.
Lure and block
Common tactics to manipulate the enemy’s movements and wear down their strength.
The Evolution of Warfare: From Ritual to Pragmatism
In this chapter, Sun Tzu articulated a fundamental tactical principle:
“Thus, the army that is first on the battlefield and awaits the enemy is at ease; the army that arrives later and rushes into battle is exhausted. Therefore, the skilled commander forces the enemy to come to him, and is not forced to come to the enemy.”
On the surface, this means that the side which secures a favorable position first fights with ease, while the latecomer fights in fatigue. However, beneath this simple logic lies a profound paradigm shift in ancient Chinese military thought. It marked the transition from ritualistic combat to pragmatic warfare, where seizing the initiative and exploiting vulnerabilities became paramount.
The Era of Ritual Warfare
Before Sun Tzu, from the Shang and Zhou dynasties to the early Spring and Autumn period, warfare was essentially a noble pursuit governed by strict codes of conduct. Battles were fought between aristocrats who adhered to agreed-upon rules of engagement. Both sides were expected to arrive at the battlefield simultaneously, deploy their formations in an orderly manner, and commence fighting only at the appointed time. The objective was not total annihilation, but rather to demonstrate martial virtue and achieve a decisive but honorable victory.
The Battle of Hong River: A Clash of Ideologies
This gradual transformation was epitomized by the Battle of Hongshui (Hong River) in 638 BC. After the death of Duke Huan of Qi, Duke Xiang of Song, despite ruling a relatively small state, harbored ambitions of becoming the hegemon. His brother, the Grand Marshal Zi Yu, warned against this, but Duke Xiang proceeded to attack the state of Zheng. In response, the powerful state of Chu sent an army to aid Zheng, leading to a confrontation at the Hong River.
During the battle, as the Chu army was only halfway across the river, Zi Yu urged Duke Xiang to attack, arguing that they should exploit the enemy’s vulnerability while they were numerically superior. Duke Xiang refused, citing the sacred rules of war. Even when the Chu troops had crossed but had not yet formed their battle lines, Zi Yu pleaded for a preemptive strike. Again, Duke Xiang refused, insisting that attacking an unformed enemy was dishonorable. The result was a catastrophic defeat for Song, and Duke Xiang was mortally wounded by an arrow. Yet, until his death, he never regretted his adherence to martial etiquette.
The Four Rules of Chivalric Combat
The Zuo Zhuan (Commentary of Zuo) records Duke Xiang’s four rules of engagement: “A gentleman does not inflict a second wound on an already injured enemy; he does not take prisoners with gray hair; he does not exploit natural hazards (such as attacking while the enemy is crossing a river); and he does not beat the drum to attack before the enemy has formed their lines.” As a descendant of the Shang dynasty, Duke Xiang believed it was his duty to uphold these ancient rites. The Gongyang Zhuan even praised him for “facing a great matter without forgetting the great rites.”
The Dawn of Pragmatic Warfare
While later generations often viewed Duke Xiang as a symbol of pedantry, historical figures like Confucius and Sima Qian recognized his commitment to the traditional moral order. However, the ideological clash between Duke Xiang and his brother Zi Yu served as the prelude to the military revolution championed by Sun Tzu. By the late Spring and Autumn period, the nature of war had fundamentally changed. It was no longer a contest of chivalry and moral virtue; it was a brutal struggle for survival. The objective shifted from merely defeating the opponent in a gentlemanly duel to completely eliminating the enemy. Sun Tzu’s philosophy of “forcing the enemy to come to him” perfectly encapsulated this new, pragmatic era of total war.
孫子曰：凡先處戰地而待敵者佚，後處戰地而趨戰者勞。故善戰者，致人而不致于人。能使敵人自至者，利之也；能使敵不得至者，害之也。故敵佚能勞之，飽能飢之，安能動之。
