Polish–Lithuanian–Teutonic War (Great War)(1411)
6 August 1409 - 1 February 1411
Kingdom of Poland - Grand Duchy of Lithuania Alliance
Commander: King Władysław II Jagiełło and Grand Duke Vytautas
Initial Combat Strength

ⓘ Analysis Parameter: Raw combat force projection only. Does not reflect the mathematical average of operational quality scores.
Decisive Force Multiplier: Multi-ethnic coalition structure (Polish, Lithuanian, Ruthenian, Tatar, Czech), the pontoon bridge maneuver across the Vistula, and the joint operational doctrine between Jogaila and Vytautas served as the decisive force multiplier.
Teutonic Order State
Commander: Grand Master Ulrich von Jungingen
Initial Combat Strength
%37
ⓘ Analysis Parameter: Raw combat force projection only. Does not reflect the mathematical average of operational quality scores.
Decisive Force Multiplier: Heavily armored knight cavalry, advanced castle systems and the fortified structure of Marienburg; however, the annihilation of the command staff at Grunwald collapsed the force multiplier.

Operational Capacity Matrix
5 Military Metrics — Staff Scoring System
Polish-Lithuanian forces secured logistical superiority through the pontoon bridge across the Vistula and the assembly hub at Czerwinsk; while the Teutonic Order held interior lines in defense, its supply network collapsed after Grunwald.
Jogaila and Vytautas successfully unified multi-ethnic forces under a single operational plan; von Jungingen lost the initiative by withdrawing from the Drewenz defense, and the chain of command collapsed at Grunwald.
The Polish-Lithuanian command refused to force the Drewenz crossing and pivoted toward the river's headwaters, compelling the Teutons into a war of maneuver; the Order was dragged into parallel pursuit and into a trap.
The Polish-Lithuanian side executed deception operations through border raids, concealing the true operational axis; Teutonic intelligence remained fixated on a dual-axis attack and deployed incorrectly at Schwetz.
Teutonic heavy cavalry and fortress systems were strong multipliers, but the multi-ethnic Polish-Lithuanian coalition combining Tatar light cavalry and Czech mercenaries produced both numerical and tactical superiority.

Victory Without Fighting · Intelligence Asymmetry · Heaven and Earth
Victory Without Fighting
The Polish-Lithuanian side overcame diplomatic traps such as Wenceslaus's mediation and Sigismund's offer of a crown to Vytautas, preserving the integrity of the Ostrów Agreement; despite spending 360,000 florins/ducats, the Teutons could not fracture the alliance.
Intelligence Asymmetry
Through border raids and false axis maneuvers, the Polish-Lithuanian side misled the Teutons on the concentration point; von Jungingen recognized the unified Polish-Lithuanian operation far too late.
Heaven and Earth
The forested and lightly undulating terrain between the villages of Grunwald, Tannenberg, and Łodwigowo constrained the shock charge of Teutonic heavy cavalry; July heat and prolonged marching wore down the Order's armored force.
Western War Doctrines
War of Annihilation
Maneuver & Interior Lines
Polish-Lithuanian forces completed the 80 km transit from the Czerwinsk assembly point to the Prussian border in approximately one week, generating an interior lines advantage; the Teutons were forced into parallel pursuit.
Psychological Warfare & Morale
The legitimacy provided by the Samogitian uprising and the leadership of Jogaila-Vytautas elevated coalition morale; von Jungingen's rage over the Gilgenburg sack led to emotional decision-making.
Firepower & Shock Effect
The initial charge of Teutonic heavy cavalry pushed back the Lithuanian line, but the flanking intervention of Polish heavy cavalry and the return maneuver of Tatar light cavalry reversed the shock balance.
Adaptive Staff Rationalism
Center of Gravity · Intelligence · Dynamism
Center of Gravity
The Polish-Lithuanian command correctly directed the center of gravity not at Marienburg but at the Teutonic field army; von Jungingen held his center of gravity at Schwetz, deploying to the wrong sector.
Deception & Intelligence
Border raids, false axes, and concealment of the assembly point constituted a classical deception operation; the Teutons were locked into the dual-attack scenario and fell victim to military deception.
Asymmetric Flexibility
The Polish-Lithuanian side demonstrated doctrinal flexibility by pivoting east rather than forcing the Drewenz defense; the Teutons could not break from their static castle-river defensive doctrine and lost the war of maneuver.
Section I
Staff Analysis
The Great War stands as one of the largest coalition operations of medieval Europe. While the Teutonic Order held technical superiority through heavily armored cavalry and fortified castle systems, the Polish-Lithuanian coalition balanced this advantage through numerical weight, multi-ethnic force composition, and superior strategic coordination. The unification of forces at Czerwinsk by Jogaila and Vytautas and the pontoon bridge maneuver across the Vistula represent one of the finest examples of medieval logistics. Von Jungingen chose central deployment at Schwetz seeking interior lines advantage but recognized allied intentions too late. At Grunwald, the Teutonic center of gravity was annihilated.
Section II
Strategic Critique
The Teutonic command staff suffered strategic blindness in intelligence assessment by remaining fixed on the dual-axis attack scenario; failing to calculate that Poland and Lithuania would unite on a single operational axis was a major staff failure. Withdrawing prematurely from the Drewenz River defense and emotionally seeking battle after the Gilgenburg atrocity were von Jungingen's most critical errors. The Polish-Lithuanian side, however, failed to maintain sufficient weight in the Marienburg siege after Grunwald, preventing the tactical victory from converting into full strategic capitulation. Nevertheless, the battle bears the character of an annihilation engagement through the physical destruction of the Teutonic military elite, with decisive long-term strategic effects.
