PROBLEM: Passage: Švitrigaila was losing his influence in the Slavic principalities and could no longer resist Poland and Sigismund. On 4 September 1437 he attempted to reconcile with Poland: he would rule the lands that still backed him , and after his death these territories would pass to the King of Poland. However, under strong protest from Sigismund, the Polish Senate declined to ratify the treaty . In 1438 Švitrigaila withdrew to Moldavia. The reign of Sigismund Kęstutaitis was brief — he was assassinated in 1440. Švitrigaila returned from exile in 1442 and ruled Lutsk until his death a decade later. Jogaila's son Casimir IV Jagiellon, born in 1426, received approval as a hereditary hospodar from Lithuania's ruling families in 1440. This event is seen by the historians Jerzy Lukowski and Hubert Zawadzki as marking the end of the succession dispute.
Question: What year did Švitrigaila die?

SOLUTION: date

PROBLEM: Passage: At the beginning of World War II the 10th Cavalry was relegated to caretaker duties at Fort Leavenworth, Kansas. In 1942 the regiment was moved to Camp Lockett, California, replacing the 11th Cavalry in its duties as the southern defense of the Western Defense Command, under LTG DeWitt. 153 NCOs of this regiment would later be assigned to the newly organized 28th Cavalry Regiment forming its cadre, and filling out the 4th Cavalry Brigade, which would remain in existence after the deactivation of the 2nd Cavalry Division, and its subsequent reactivation. In the summer of 1943, the 10th and 28th Cavalry Regiments fought wildfires in the Cleveland National Forest. In 1944, the entire 2nd Cavalry Division was shipped out to Oran, North Africa; where it disembarked and was deactivated on 9 March 1944. Although trained as combat soldiers, the soldiers of this regiment, and other regiments of the 2nd Cavalry Division were reorganized as combat support and combat service support units. Some would see combat as replacement soldiers of the 92nd Infantry Division.
Question: When was the 2nd Cavalry Division sent to North Africa?

SOLUTION: date

PROBLEM: Passage: In 1552 Charles V had borrowed over 4 million ducats, with the Metz campaign alone costing 2.5 million ducats. Shipments of treasure from the Indies totalled over two million ducats between 1552-53. By 1554, the cash deficit for the year was calculated to be over 4.3 million ducats, even after all tax receipts for the six ensuing years had been pledged and the proceeds spent in advance. Credit at this point began costing the crown 43 percent interest . By 1557 the crown was refusing payment from the Indies since even this was required for payment of the war effort . French finances during the war were mainly financed by the increase in the taille tax, as well as indirect taxes like the gabelle and customs fees. The French monarchy also resorted to heavy borrowings during the war from financiers at rates of 10-16 percent interest. The taille was estimated in collection for 1551 at around six million livres. During the 1550s, Spain had an estimated military manpower of around 150,000 soldiers, whereas France had an estimated manpower of 50,000.
Question: How many fewer million ducats did the Metz campaign cost than what Charles V borrowed?

SOLUTION:
number
