Battle of Grunwald

Timeline

1. 1409–1410Czerwińsk to the Prussian border · PolandThe Samogitian uprising of 1409 brought Poland-Lithuania and the Teutonic Order to war. When the truce expired, Władysław and Vytautas met at Czerwińsk per their planned strategy, crossed the river in late June, and entered Prussia on 9 July, aiming directly at the Order's capital Marienburg and disrupting its divided defensive deployment.
2. 1410Grunwald battlefield · Warmia-MasuriaThe Order formed up first while Władysław delayed the attack. Vytautas led Lithuanian light cavalry against the Order's left wing, then most withdrew, and the pursuing Order disrupted its own formation. Polish heavy cavalry broke the center; Grand Master Ulrich von Jungingen was killed leading a reserve counterattack, and much of the Order's command was killed or captured.
3. 1410Marienburg · Pomeranian VoivodeshipMost Prussian castles surrendered without a fight at first, but Heinrich von Plauen promptly fortified Marienburg; short of ammunition and supplies, the allies lifted the siege and withdrew. The Order quickly recovered its lost territory and the war moved into negotiations; the Order's military elite had been devastated, and the balance of power in northeastern Europe shifted for good.
