Powała of Taczew: Pan Mikołaj Powała z Taczewa ("Sir Mikołaj Powała of Taczew") of Ogończyk coat of arms was a Polish knight in the Middle Ages.  He took part in the Battle of Grunwald of 1410.

Battle of Grunwald: The Battle of Grunwald, First Battle of Tannenberg or Battle of Žalgiris, was fought on 15 July 1410 during the Polish–Lithuanian–Teutonic War.  The alliance of the Kingdom of Poland and the Grand Duchy of Lithuania, led respectively by King Władysław II Jagiełło (Jogaila) and Grand Duke Vytautas, decisively defeated the German–Prussian Teutonic Knights, led by Grand Master Ulrich von Jungingen.  Most of the Teutonic Knights' leadership were killed or taken prisoner.  Although defeated, the Teutonic Knights withstood the siege of their fortress in Marienburg (Malbork) and suffered minimal territorial losses at the Peace of Thorn (1411) (Toruń), with other territorial disputes continuing until the Peace of Melno in 1422.  The knights, however, would never recover their former power, and the financial burden of war reparations caused internal conflicts and an economic downturn in the lands under their control.  The battle shifted the balance of power in Central and Eastern Europe and marked the rise of the Polish–Lithuanian union as the dominant political and military force in the region.

Battle of Wilkomierz: The Battle of Wilkomierz (see other names) took place on September 1, 1435 near Ukmergė in the Grand Duchy of Lithuania.  With the help of military units from the Kingdom of Poland, the forces of Grand Duke Sigismund Kęstutaitis soundly defeated Švitrigaila and his Livonian allies.  The battle was a decisive engagement of the Lithuanian Civil War (1432–38).  Švitrigaila lost most of his supporters and withdrew to southern Grand Duchy; he was slowly pushed out and eventually made peace.  The damage inflicted upon the Livonian Order has been compared to the damage of Battle of Grunwald upon the Teutonic Order.  It was fundamentally weakened and ceased to play a major role in Lithuanian affairs.  The battle can be seen as the final engagement of the Lithuanian Crusade.

Grunwald Swords: The Grunwald Swords (Polish: "miecze grunwaldzkie" ) were a gift presented by Ulrich von Jungingen, the Grand Master of the Order of Teutonic Knights, to King Władysław II Jagiełło of Poland and Grand Duke Vytautas the Great of Lithuania on 15 July 1410, just before the Battle of Grunwald (Tannenberg).  The gift, a pair of simple bare swords, was a formal invitation to the battle.  After the Polish-Lithuanian victory, both swords were taken as a war trophy by King Władysław II to Kraków, Poland's capital at the time, and placed in the treasury of the Royal Wawel Castle.
