Battle of Grunwald

July 15, 1410

The Polish-Lithuanian hosts under Jogaila and Vytautas crushed the Teutonic Knights in a dusty forest clearing in Prussia. Grand Master Ulrich von Jungingen died in the melee; two hundred white-mantled knights were left face-down in the ferns. The Order's four-century crusade against the pagan Baltic was broken in an afternoon.
