[Q]: Question: How old was Yoshinaka when Enichi-ji's general was killed?

[Q]: Question: Who was the ruler of the Crown of the Polish Kingdom when Königsberg was besieged by Polish forces? Passage:In 1454 the Prussian Confederation rebelled against the Teutonic Knights and formally asked the Polish King Casimir IV Jagiellon to incorporate Prussia into the Kingdom of Poland as a fief. This marked the beginning of the Thirteen Years' War (1454-66) between the State of the Teutonic Order and the Crown of the Kingdom of Poland. While Königsberg's three towns initially joined the rebellion, Altstadt and Löbenicht soon rejoined the Teutonic Knights and defeated Kneiphof in 1455. Grand Master Ludwig von Erlichshausen fled from the crusaders' capital at Castle Marienburg to Königsberg in 1457; the city's magistrate presented Erlichshausen with a barrel of beer out of compassion. When western Prussia was transferred to victorious Poland in the Second Peace of Thorn (1466), which ended the Thirteen Years' War, Königsberg became the new capital of the reduced monastic state, which became a fief of the Crown of the Polish Kingdom. The grand masters took over the quarters of the marshal. During the Polish-Teutonic War (1519–1521), Königsberg was unsuccessfully besieged by Polish forces led by Grand Crown Hetman Mikołaj Firlej.
