After_the_Battle_of_Grunwald_-_Alfons_Mucha
After the Battle of Grunwald (1st Tannenberg) 1410 http://en.wikipedia.org/wiki/Battle_of_Grunwald during the Polish–Lithuanian–Teutonic War. The early fourteenth century was marked by military incursions by the German Order of Teutonic Knights into the land of the Northern Slavs. In response, The Polish King Wladyslaw Jagiello and the Czech King Vaclav IV signed a defensive treaty which was first acted upon at the battle of Grunwaldu in 1410 when the Slavs won an important victory. Mucha elects to illustrate not the fighting but the aftermath, with the Polish King holding his face in sorrow as he views the cost to both enemy and ally.
