The Battle of Grunwald, fought on 15 July 1410, was one of the largest and most significant engagements of the medieval period. It marked a decisive confrontation between the allied forces of the Kingdom of Poland and the Grand Duchy of Lithuania, led by King Władysław II Jagiełło and Grand Duke Vytautas, and the Teutonic Order, commanded by Grand Master Ulrich von Jungingen.
Historical Background
The Teutonic Order had been expanding aggressively in the Baltic region since the 13th century, often at the expense of local Slavic and Baltic populations. Tensions escalated with Poland and Lithuania due to territorial disputes and religious justifications for crusade. The formal alliance between Poland and Lithuania, sealed through the Union of Krewo and later the Union of Vilnius and Radom, laid the groundwork for coordinated military resistance. Grunwald became the flashpoint of this prolonged conflict.
Forces Involved
The armies brought to Grunwald were vast by medieval standards, reflecting both sides’ desire for a decisive resolution. Below is a breakdown of the leadership and composition of the forces:
| Side | Leader(s) | Estimated Strength | Composition |
|---|---|---|---|
| Poland–Lithuania Alliance | King Władysław II Jagiełło (Poland), Grand Duke Vytautas (Lithuania) | Approx. 29,000–35,000 | Polish knights and levies, Lithuanian light cavalry, Ruthenians, Tatars, Czech mercenaries |
| Teutonic Order | Grand Master Ulrich von Jungingen | Approx. 21,000 | Teutonic knights, German mercenaries, Prussian, Livonian, and Western European crusaders |
Arms and Armour
The weaponry and armour at Grunwald reflected the transitional period in medieval warfare, with heavily armoured knights fighting alongside lightly equipped horsemen and infantry.
Swords and Blades
- Knightly Arming Sword: The standard sidearm of Western European and Polish knights. These swords featured cruciform hilts and straight double-edged blades, ideal for both thrusting and cutting. Blade lengths typically ranged from 70 to 85 cm.
- Longswords: Favoured by some Teutonic knights and mercenaries. These had longer grips for two-handed use and slightly tapered blades for penetrating armour.
- Sabres and Curved Blades: Used predominantly by Lithuanian, Tatar, and Ruthenian cavalry. These were lighter, single-edged swords suited for fast slashing attacks from horseback.
- Falchions: A minority of infantry and light cavalry carried falchions, which were heavy-bladed, single-edged swords that could deal crushing blows, particularly against lightly armoured foes.
Armour
- Plate Armour: The elite of both sides, especially Teutonic knights and Polish nobility, wore full or partial plate armour. This included breastplates, pauldrons, greaves, and gauntlets. Helmets such as bascinets with visors were widespread.
- Mail (Chainmail): Still common, especially among Lithuanian troops, who often wore mail hauberks combined with padded garments.
- Lamellar and Scale Armour: Seen among the Lithuanian and Tatar contingents. These forms of armour offered flexibility and were lighter than full plate.
- Shields: The Teutonic knights carried large kite or heater shields, emblazoned with their black cross on white. Polish and Lithuanian warriors used a mix of round, oval, and kite shields, often painted with heraldic symbols or tribal motifs.
Timeline of the Battle

| Morning, 15 July | Polish and Lithuanian forces begin deployment on the fields near the villages of Grunwald, Tannenberg, and Łodwigowo. |
| Midday | The Teutonic Order takes a defensive position, forming a dense central front with heavy cavalry. |
| Noon–Early Afternoon | Lithuanian cavalry, led by Vytautas, launch the initial attack on the Teutonic right. A tactical withdrawal follows, leading some to believe they are in full retreat. |
| Mid-Afternoon | Polish forces engage the Teutonic left and centre. The battle becomes chaotic and intense. The Lithuanians return, flanking the Teutonic forces. |
| Late Afternoon | Grand Master Ulrich von Jungingen leads a direct charge but is killed in the melee. Teutonic morale collapses. |

Archaeology and Physical Evidence
Modern archaeological work has concentrated on battlefield surveys near the villages of Stębark and Grunwald. Notable discoveries include:
- Fragments of swords and spearheads, consistent with 15th-century forms
- Arrowheads of Lithuanian and Tatar origin
- Horseshoes and harness fittings
- Burial pits containing remains of fallen soldiers, many bearing trauma from edged weapons
The scale of findings supports contemporary descriptions of a massive engagement, with widespread casualties and a variety of combatants from different cultural backgrounds.
Legacy and Impact
Grunwald marked a catastrophic loss for the Teutonic Order. While it retained some strongholds afterward, the defeat shattered its image of invincibility and began its gradual decline. Poland and Lithuania emerged strengthened, with their alliance solidified and their position in Central and Eastern Europe enhanced.
The battle holds strong symbolic significance in Polish, Lithuanian, and Belarusian national memory. It has been commemorated in literature, painting (most famously by Jan Matejko), and film. Politically, it became a foundational myth for resistance against external domination in later centuries.
The Battle of Grunwald stands as one of the defining conflicts of the medieval era. Its sheer scale, multinational composition, and the dramatic reversal of Teutonic fortunes have cemented its place in European military history. Both in physical remnants and cultural memory, it continues to offer insight into the warfare, diplomacy, and identity of late medieval Europe.
