On July 15, 1410, under a summer sun in the fields of Grunwald, two worlds collided in the largest battle medieval Europe had ever seen.

The Teutonic Knights — the most powerful military order in the world — faced a combined Polish-Lithuanian-Ruthenian army across a plain that would become one of history's most consequential battlefields.

In this AI-reconstructed documentary, we follow every phase of the battle decision by decision:

⚔️ The Teutonic Order — who they were, how they built a crusader state from nothing, and why they had to be stopped
🏰 Jagiełło and Vytautas — the king and the grand duke whose alliance changed the balance of power in Europe
🐴 The Lithuanian feigned retreat — the masterstroke that nearly worked too well
🛡️ The charge of the heavy cavalry and the moment Grand Master Ulrich von Jungingen rode to his death
📜 Jan Długosz and the chroniclers — what the medieval sources actually tell us
🌍 Why it mattered: the battle that broke the Teutonic Order's grip on the Baltic forever
🔥 The aftermath: captured banners, ransom, and a peace treaty that reshaped Central Europe

This is not a legend. This is Grunwald as the men who stood in those fields lived it — hour by hour, decision by decision.
