ⓘ Analysis Parameter: Raw combat force projection only. Does not reflect the mathematical average of operational quality scores.
Decisive Force Multiplier: Despite ethnic and religious diversity, high coordination and shared goal; the heterogeneous force of Orthodox Ruthenians, Muslim Tatars, and pagan Samogitians was underestimated by the Teutons but turned into a force multiplier under effective unified command.
Teutonic Order
Commander: Grand Master Ulrich von Jungingen
Initial Combat Strength

ⓘ Analysis Parameter: Raw combat force projection only. Does not reflect the mathematical average of operational quality scores.
Decisive Force Multiplier: Heavy cavalry and disciplined professional army; however, leadership failure and lack of coordination among allied reinforcements from Western Europe prevented effective use of technological superiority on the battlefield.

5 Military Metrics — Staff Scoring System
The Polish-Lithuanian coalition sustained the campaign by leveraging its vast territory for manpower and resources; whereas the Teutons relied on reinforcements from Western Europe and mercenaries, leading to lower sustainability and logistical difficulties during the Marienburg siege.
The dual command structure (Jagiełło and Vytautas) posed initial risks but maintained cohesion through adherence to the joint plan; in contrast, the death of the Grand Master after losing the battle crippled the Teutonic chain of command.
The Polish-Lithuanian army gained the advantage by executing a successful crossing of the Vistula and bypassing the Drewenz River; the Teutons were forced to meet the enemy at an unexpected location, losing the ability to choose the battlefield.
Both sides tracked each other's movements, but the Polish-Lithuanian deception through border raids and the secret concentration plan succeeded; the Teutons realized the true objective too late, forfeiting the initiative.
Despite the Teutonic heavy cavalry and technological edge, the Polish-Lithuanian morale, religious motivation, and Vytautas's use of mobile Tatar troops proved decisive in the battle.

Asian Art of War
Victory Without Fighting · Intelligence Asymmetry · Heaven and Earth
Victory Without Fighting
Pre-war diplomatic efforts were unsuccessful; however, after Grunwald, Poland-Lithuania isolated the Order politically by swaying its allies to their side.
Intelligence Asymmetry
The Teutons perceived the ethnic and religious diversity of the Polish-Lithuanian army as a weakness, but failed to foresee how this diversity became an advantage under unified command.
Heaven and Earth
The open terrain of the battlefield allowed heavy cavalry maneuver, but the unexpected deployment and use of terrain by the Polish-Lithuanian army disrupted Teutonic formations; the summer season was conducive to prolonged operations.
Western War Doctrines
War of Annihilation
Maneuver & Interior Lines
The Polish-Lithuanian army utilized speed by quickly assembling at Czerwińsk and crossing the Vistula; the Teutons responded with a parallel march but failed to seize the initiative.
Psychological Warfare & Morale
The Teutonic Knights had high morale due to their religious mission and chivalric pride; however, the crushing defeat at Grunwald and the death of their leaders led to psychological collapse, while on the Polish-Lithuanian side, motivation as a Christian bulwark against the pagan threat boosted morale.
Firepower & Shock Effect
The initial charge of the Teutonic heavy cavalry was strong but failed to break the Polish-Lithuanian lines; in contrast, the countercharge of the allied cavalry and the harassing fire of Tatar light cavalry created a shock effect.

Center of Gravity · Intelligence · Dynamism
Center of Gravity
The Teutons failed to identify the correct center of gravity; the Polish-Lithuanian army focused on forcing the enemy's main body into a decisive battle at Grunwald and destroying it through envelopment.
Deception & Intelligence
The Polish-Lithuanian army concealed its main axis of advance through border raids and used a feigned retreat tactic (the Lithuanian wing) to draw the Teutons into a trap on the battlefield.
Asymmetric Flexibility
The Polish-Lithuanian forces demonstrated doctrinal flexibility by combining heavy cavalry shock, light cavalry skirmishing, siege operations, and deception; the Teutons relied rigidly on traditional heavy cavalry charges.
Section I
Staff Analysis
Although the Polish-Lithuanian coalition was caught unprepared at the start of the war, it used the truce period effectively to mass a large army and conducted a strategic deep maneuver to force the Teutons into a decisive battle. In contrast, the Teutons recognized the enemy's intentions too late and lost the initiative. At Grunwald, the coalition exploited its numerical and morale superiority to annihilate the core of the Teutonic army; however, the failure to capture Marienburg limited the strategic gains of the victory.
Section II
Strategic Critique
The greatest mistake was Teutonic Grand Master Ulrich von Jungingen's failure to anticipate the enemy's unified advance, leading to unnecessary division of forces and an ineffective battle formation at Grunwald. Conversely, the Polish-Lithuanian command delayed the siege of Marienburg, allowing the enemy to recover and prolonging the war. Heinrich von Plauen's determined defense of the capital was commendable.
