5 Military Metrics — Staff Scoring System
The Polish-Lithuanian forces shortened their supply lines by operating as a unified army and received logistical support from friendly territories. The Teutonic Order, relying on garrisons in a defensive posture, faced supply difficulties for a sudden battle due to their dispersed units.
The Polish-Lithuanian command exhibited harmonious cooperation, with Jagiełło's cautious leadership and Vytautas's tactical initiative. In the Teutonic Order, Grand Master von Jungingen's centralized command style and his death during battle led to a collapse in coordination.
The Polish-Lithuanian army kept Teutonic forces dispersed through border raids and chose open terrain on a hot summer day, disadvantageous for heavily armored knights, gaining a tactical edge.
The Polish-Lithuanian alliance misled the enemy into expecting a two-pronged invasion through strategic deception, while actually uniting their forces to march on Marienburg. The Teutonic Order detected this movement too late, suffering from an intelligence failure.
While the Teutonic heavy cavalry was superior in shock power, the flexibility of the Lithuanian light cavalry, Tatar archers, and diverse ethnic units in the Polish-Lithuanian army provided an advantage in a prolonged attrition battle.

Victory Without Fighting
Polish-Lithuanian diplomacy won strategic isolation before the battle: Vytautas secured a truce with the Livonian Order, depriving the Teutons of an ally, and rejected Sigismund's crown offer to preserve the alliance.
Intelligence Asymmetry
The Polish-Lithuanian command correctly predicted the enemy's defensive plans and successfully concealed their forces through deception operations. The Teutons, unaware of the enemy's plan to unite, were caught unprepared.
Heaven and Earth
The extreme heat on the day of battle exhausted the Teutonic knights in heavy armor; the open terrain choice provided the Polish-Lithuanian forces freedom of maneuver, playing a critical role in neutralizing the Teutonic cavalry charge.
Western War Doctrines
Battle of Annihilation
Maneuver & Interior Lines
The Polish-Lithuanian army united quickly using interior lines and misled the enemy with dynamic maneuvers such as Vytautas's feigned retreat. The Teutonic Order used its heavy cavalry with insufficient flexibility, falling into a trap by pursuing the false opening.
Psychological Warfare & Morale
The Teutonic knights' arrogant challenge of the swords incited revenge feelings in the Polish-Lithuanian troops, reversing the morale advantage. The death of the Grand Master caused a sudden morale collapse on the Teutonic side.
Firepower & Shock Effect
The initial shock wave of the Teutonic heavy cavalry rattled the Lithuanian flank, but the determined resistance of the Polish heavy cavalry and infantry support absorbed this effect. The Polish-Lithuanian envelopment maneuver created a decisive shock effect that delivered the final blow.

Center of Gravity
The Polish-Lithuanian command directed their main striking power against the Teutonic left flank, collapsing the enemy's center of resistance. The Teutons focused their Schwerpunkt on the Polish center but were encircled by the unexpected return of the Lithuanian flank.
Deception & Intelligence
The planned feigned retreat of the Lithuanian light cavalry drew the Teutonic cavalry away from the main battle line into a trap, becoming a deception strategy that decided the battle.
Asymmetric Flexibility
Despite its multi-ethnic composition, the Polish-Lithuanian army quickly adapted to changing battle conditions; the Teutonic Order, despite its material superiority, failed to show flexibility with its rigid formations and could not prevent encirclement.
Section I
Staff Analysis
Pre-battle assessment shows that the Polish-Lithuanian alliance was numerically superior but at a disadvantage in equipment against the Teutonic knights. The Teutonic Order, with an estimated 11,000 to 27,000 troops, relied heavily on disciplined heavy cavalry and mercenary infantry. In contrast, the Polish-Lithuanian forces, numbering between 16,500 to 39,000, were a multi-ethnic host: Polish heavy cavalry, Lithuanian light cavalry, Tatar archers, and various infantry units. Jagiełło and Vytautas had deceived the enemy through border raids and secretly marched a unified army toward Marienburg, achieving strategic surprise. Grand Master von Jungingen remained in a defensive posture, concentrating forces at Schwetz, but lost the initiative by detecting the main thrust too late. The open terrain chosen for the battle limited the charging power of the Teutonic heavy cavalry and allowed the Polish-Lithuanian forces freedom of maneuver. The planned feigned retreat of the Lithuanian light cavalry dispersed the Teutonic Schwerpunkt and set the stage for an encirclement maneuver that decided the battle. Ultimately, the Polish-Lithuanian side succeeded in destroying the technologically superior Teutonic army through a battle strategy based on flexibility and deception.
Section II
Strategic Critique
Grand Master von Jungingen's most critical error was falling for the enemy's strategic deception and relying on scattered garrisons rather than concentrating his forces. Moreover, during the battle, his pursuit of the Lithuanian feigned retreat weakened his Schwerpunkt and created an irreparable tactical gap. The Polish-Lithuanian command successfully coordinated their multi-ethnic army, and Vytautas's feigned retreat exemplified textbook military deception. Jagiełło's cautious positioning of his headquarters ensured command and control even at the battle's most critical moment. Consequently, the Teutonic Order's defeat was not merely a tactical rout but the result of a strategic weakness.
