Stratagems and Counterstratagems

Stratagems and Counterstratagems names a recurring method of action in the novel: a commander does not merely meet an opponent’s strength but studies what the opponent believes, then uses that belief to redirect the contest. The method depends on concrete conditions—weak walls, limited supplies, fog, boats, family loyalties—as much as on deception. Across the story, plans succeed when they make an enemy’s assumptions part of the mechanism, and fail when the apparent evidence is read correctly or the physical situation contradicts the ruse.

Terrain, Supplies, and the Enemy’s Expectations

The principle is visible in the defense of Nanyang, where Jia Xu watches Cao Cao’s preparations and infers that he has noticed the southeastern wall’s weakness: its earth ramparts are crumbling, and wooden stakes form much of its barrier. Cao Cao, however, piles materials on the northwest side to suggest that this is where he intends to attack. Jia Xu advises Zhang Xiu to answer deception with deception: hide experienced troops near the genuinely vulnerable southeastern wall, while placing ordinary people in armor on the northwest wall. The proposed trap turns Cao Cao’s apparent insight into a liability, because his confidence about the enemy’s intentions is itself being manipulated.

Supply limits shape the same logic in Cao Cao’s confrontation with Yuan Shao at Guandu. Yuan Shao commands a vastly larger army, while Cao Cao can field only about a tenth as many men. Xun You therefore urges an immediate attack: Cao Cao’s veterans may be able to defeat a much larger force, but their supplies will not sustain a prolonged campaign. The decision to act quickly is not a trick in isolation; it is a response to the strategic constraint that makes delay dangerous. The exchange of accusations between the two commanders also frames their military contest as a struggle over political legitimacy, while the disparity in numbers and supplies defines the immediate practical stakes.

Feints, Command, and Reversal

At Bowang, Kong Ming’s first test as a commander depends on coordinated positions and a staged retreat. He orders Guan Yu to conceal troops in the hills and wait for flames before attacking the enemy’s rear and supply train. Zhang Fei is to hide behind the forest and strike the army stores at Bowang when he sees the fire. Other commanders are assigned to prepare fires on both sides of the ravine, while Zhao Zilong is to lead an advance party and pretend to flee after encountering Cao Cao’s men. The plan links a visible signal to separate attacks on the enemy’s route, rear, and supplies. Its precision also tests whether commanders who distrust Kong Ming will follow his orders: Guan Yu and Zhang Fei are skeptical, but Xuande sharply rebukes them when they challenge the plan.

The contest at Jieting supplies a counterexample in which knowledge of military theory cannot compensate for misjudgment. Ma Su, responsible for defending the position, rejects Wang Ping’s advice to hold the road and instead occupies a hill, citing military texts. When the enemy surrounds him, the hill has no water; his troops become desperate, begin to desert, and eventually try to break out. Wang Ping’s smaller force cannot rescue them, and the position falls. The episode makes the cost of a mistaken reading of terrain specific: an elevated position that Ma Su treats as advantageous leaves his army cut off from water and unable to control the route that matters.

The Red Cliffs Contest of Appearances

Before Red Cliffs, Zhou Yu uses a staged display of intoxication to deceive Jiang Gan. He entertains his old acquaintance among the commanders and the preparations for war, then pretends to sleep deeply in his tent. Jiang Gan, unable to persuade Zhou Yu to change sides, searches the tent and discovers a letter apparently from Cai Mao and Zhang Yun. It claims that they serve Cao Cao only under compulsion and are positioned to kill him. Jiang Gan steals it, hoping that the discovery will restore Cao Cao’s confidence in him, and escapes the next morning. The letter’s apparent authority rests on its plausibility to a reader already anxious about loyalty; Cao Cao accepts its implications, and Cai Mao and Zhang Yun are executed. The deception thus converts a forged appearance of treachery into an actual loss of experienced commanders.

Zhou Yu then tries to make Kong Ming’s skill and knowledge a trap of their own. He asks him to provide one hundred thousand arrows, first setting a deadline of ten days. Kong Ming proposes three days instead, accepts the task, and privately asks Lu Su for twenty boats, thirty men per boat, and a thousand straw bales covered in black cloth. For the first two days he appears to do nothing. During the fourth watch of the third night, the boats enter a dense fog and approach Cao Cao’s side of the river. Their sailors beat drums and shout as though a large force is attacking. Cao Cao, hearing the commotion, orders his troops to shoot into the fog; ten thousand archers and crossbowmen fire at what they take to be an approaching enemy. Their arrows lodge in the straw barriers. As the fog lifts at sunrise, Kong Ming turns the boats back, with the bales bristling with arrows, and calls out his thanks to Cao Cao. The stratagem makes Cao Cao’s cautious response supply the weapon that Zhou Yu’s demand had made scarce.

The sequence also establishes a counter-stratagem: Zhou Yu recognizes that apparent desertion can be exploited rather than trusted. Cao Cao and Xun You send Cai Zhong and Cai He to the southern camp as supposed defectors. Zhou Yu notices that they have not brought their families, who remain under Cao Cao’s control, and infers that they are spies. Instead of exposing them immediately, he keeps his knowledge from Lu Su and plans to use the men to carry false information north. Lu Su, meanwhile, believes Zhou Yu has been taken in and tells Kong Ming of his concern; Kong Ming understands that Zhou Yu is acting on purpose. The same apparent change of allegiance therefore means different things to each observer, and the secrecy around those interpretations becomes part of the contest.

Huang Gai provides the credible grievance Zhou Yu needs to complete the deception. He privately agrees to help destroy the enemy fleet and to appear to defect, even though the ruse requires him to accept a public punishment that will make his anger believable. At a council of war, he openly challenges Zhou Yu’s proposal to store provisions for a long campaign, arguing instead for an immediate attack or surrender. The dispute is staged to create a motive that the two spies can report to Cao Cao. Kan Ze also sends a secret message saying that Huang Gai will cross the river in a boat marked with a green flag. Cao Cao remains wary despite the corroborating letters, and Jiang Gan offers to return south in an effort to redeem his earlier failure. The layered evidence is designed to reassure Cao Cao while preserving the appearance of a real grievance.

Pang Tong’s contribution ties the scheme to the physical behavior of the ships. He points out that if each vessel can move independently, a fire on one ship will prompt the others to separate and escape. Linking them together would prevent that response and make the fleet vulnerable to a spreading fire. When Jiang Gan returns, Zhou Yu uses his presence to stage another breach in their friendship: Zhou reproaches him for the earlier theft of the letter and sends him to stay at the Western Hills monastery. The encounter distracts Jiang Gan while the larger plan continues to hide its true purpose.

The deception reaches its crisis at Red Cliffs when Huang Gai approaches in battle armor beneath a banner identifying him as the vanguard. Cao Cao sees the expected signal and interprets the approaching vessel as confirmation that the defection is real, even reading it as a sign of Heaven’s favor. Cheng Yu objects: the boats ride too high in the water to be carrying grain, and their speed, aided by the wind, makes them dangerous. His warning identifies the physical clue that contradicts the political story. The earlier illusion has led Cao Cao toward the wrong conclusion; now the vessels’ lightness reveals that the apparent delivery is not what it seems.

Political Deception and Legitimacy

Stratagems also operate through bargains and claims to political authority, not only battlefield maneuvers. After Xuande’s marriage to Lady Sun, Zhou Yu sends Lu Su with a proposal that Sun Quan’s side will campaign in the western Riverlands and eventually transfer the captured territory as a dowry, in exchange for Jingzhou. Zhou Yu privately tells Lu Su that the proposed western campaign is a pretext: the real intention is to turn aside and attack Jingzhou. Xuande and Kong Ming anticipate the maneuver. Before Lu Su enters, Kong Ming tells Xuande to agree and nod; Xuande then accepts the proposal, while Kong Ming promises support for the passing force. The apparent agreement conceals their awareness of the intended reversal and leaves Zhou Yu’s plan exposed as a plan rather than an accomplished transfer of control.

The language of legitimacy can likewise serve as an instrument in a struggle for power. Cao Pi’s accession is presented through an abdication announcement attributed to the Han emperor. It declares that signs from Heaven and the wishes of the people indicate that the Han era has ended and fortune has passed to the Cao family, invoking Yao’s precedent of yielding the throne. Sima Yi advises Cao Pi to refuse at first and to proceed through repeated appeals before the emperor is made to order an Altar of Abdication. The ritual culminates in the transfer of the jade seal and Cao Pi’s accession as emperor of Wei. In Chengdu, Kong Ming responds by proposing that Xuande be crowned as the new Han emperor, continuing the lineage against what he calls Cao Pi’s usurpation. These rival claims show how the language of Heaven, popular support, and historical precedent can be arranged to make a transfer of power appear either rightful succession or rebellion.

The Principle’s Range and Costs

Across these episodes, strategy is more than concealment. It joins intelligence to logistics: a weak wall, a shortage of arrows, a fog-covered river, a vessel’s draft, a road left undefended, or supplies that cannot last through a long campaign may decide whether an apparent plan can work. It also depends on managing what different people know. Jiang Gan mistakes a planted letter for genuine evidence; Cao Cao’s spies are recognized but turned into channels for misinformation; Lu Su misunderstands Zhou Yu’s handling of them; and Cheng Yu reads the warning sign in the boats that Cao Cao overlooks.

The consequences are not confined to clever reversals. The forged letter leads to the executions of Cai Mao and Zhang Yun, and the Jieting miscalculation costs an army its position and lives. Elsewhere, Cao Cao’s campaign against the Yuans combines deception and opportunism with a strict order that the Yuan clan not be harmed when the flooded city of Jizhou falls. The contrast matters: stratagems can be used to conserve resources, seize initiative, or shape political legitimacy, but their consequences depend on the people and communities caught in their operation. The novel repeatedly makes the test of a plan concrete: not simply whether it appears ingenious, but whether its reading of terrain, loyalty, supply, and human response proves correct.
