PROBLEM: Passage: In January 1454, the year that Casimir IV was married to Elisabeth Habsburg, the Prussian faction asked Casimir IV and protection by the Kingdom of Poland. Casimir asked the Prussian Confederation for a more formal petition. On 4 February 1454, the Secret Council of the Prussian Confederation sent a formal act of disobedience to the Grand Master. Two days later the confederacy started its rebellion and soon almost all Prussia, except for Marienburg, Stuhm , and Konitz , were free from Teutonic rule. Most of the captured Ordensburg castles were immediately destroyed. On 10 February 1454, the confederacy sent an official delegation to Poland, headed by Johannes von Baysen. By 20 February, the delegates were in Kraków and asked Casimir to bring Prussia into the Polish kingdom. After negotiating the exact conditions of incorporation, the king agreed and delegates of the Prussian Confederation pledged allegiance to Casimir on 6 March 1454. On the same day, the king agreed to all the conditions of the Prussian delegates — for instance Thorn demanded the destruction of the Polish city of Nieszawa — giving wide privileges to the Prussian cities and nobility. Three days later, Johannes von Baysen was named as the first governor of Prussia. After 15 April, most of the Prussian estates, with the exception of the Prince-Bishopric of Warmia, pledged allegiance to their new ruler. Poland sent the Grand Master a declaration of war, predated to 22 February. Both sides expected the war to end quickly.
Question: On what date did the confederacy start it's rebellion where soon after almost all Prussia was free from Teutonic rule?

PROBLEM: Passage: The Spanish were able to complete their escape to Tlaxcala. There, they were given assistance, since all 440 of them were wounded, with only 20 horses left. Maxixcatzin, Xicotencatl the Elder and Chichimecatecle told Cortés's men: "Consider yourselves at home. Rest...do not think it a small thing that you have escaped with your lives from that strong city...if we thought of you as brave men before, we consider you much braver now.":306-07 Cortés got reinforcements when the Panuco River settlement was abandoned, and supply ships arrived from Cuba and Spain. Cortés also had built 13 brigantines then had them mounted with cannons, turning Lake Texcoco into a strategic body of water to assault Tenochtitlan. Xicotencatl the Younger, however, sought an alliance with the Mexicans, but was opposed.:309-11 Cortés sent Diego de Ordaz, and the remnants of Navarez's men, on a ship to Spain, and Alonso de Ávila on a ship to Santo Domingo to represent his case in the Royal Courts.:311 Cortés was able to pacify the country, after the indigenous realized the Spaniards put "an end to the rape and robbery that the Mexicans practised." Finally, Xicotencatl the Elder, baptized as Don Lorenzo de Vargas, agreed to support Cortés's expedition against Texcoco. According to Bernal Diaz, he sent more than ten thousand warriors under the command of Chichimecatecle as Cortés marched on the day after Christmas 1520.:309, 311-12
