Problem: The war was also expensive. In the 1650s, there were over 20,000 Spanish troops in Extremadura alone, compared to 27,000 in Flanders. Between 1649 and 1654, about 29 percent  of Spanish defence spending was appropriated for fighting Portugal, a figure that rose during the major campaigns of the 1660s. Portugal was able to finance its war effort because of its ability to tax the spice trade with Asia and the sugar trade from Brazil, and it received some support from the European opponents of Spain, particularly  France and England. The 1650s were indecisive militarily but important on the political and diplomatic fronts, with the brief exception of the Battle of the Lines of Elvas in 1659. The death of João IV in 1656 signalled the beginning of the regency of his wife, followed by a succession crisis and a palace coup . Despite these domestic problems, the expulsion of the Dutch from Brazil  and the signing of a treaty with England  improved Portugal's diplomatic and financial position temporarily and gave it needed protection against a naval raid on Lisbon. Nonetheless, the overriding goal, a formal pact with France continued to evade Portugal, whose weakness and isolation had been driven home by its virtual exclusion at the negotiations for the European settlement-of-settlements, the new realpolitik of the peace of Westphalia . With this treaty and the end of hostilities in Catalonia in 1652, Spain was again ready to direct its efforts against Portugal, but it faced a lack of men, resources, and, especially, good military commanders.

How many years was the time span where 29 percent of Spanish defense spending was appropriated for fighting Portugal?
Answer: 5

Problem: In December 1340, the payment of the pledge was due. Since this did not happen, the pledged lands fell to Mecklenburg. However, no investiture of the Prince of Mecklenburg was made by the Danish king Valdemar IV Atterdag. In autumn 1342, the Pomeranian Marshal, Wedego Bugenhagen, gained control of Grimmen. In September 1343, the Mecklenburg army under Albert II succeeded in storming the town. Thanks to mediation by the towns of Stralsund and Greifswald, a ceasefire was agreed in October 1343. But the agreed arbitration never took place. Valdemar IV Atterdag, as the former feudal lord avoided making a decision, as he feared that the losing party would desert him. Because the sons of Vartislav IV of Pomerania-Wolgast could not redeem the pledged estates, but continued to claim them back, there was renewed fighting with Mecklenburg in 1351. With the support of Barnim III of Pomerania-Stettin, an army led by Baron Klaus Hahn inflicted a devastating defeat on Mecklenburg on 25 October 1351 at the Schopendamm near Loitz. Amongst the fallen on the Pomeranian side, was Count John IV the Younger of Gützkow. As the Gützkow count had no male offspring, the county of Gützkow was later seized by Barnim III.

When did Mecklenburg army under Albert II succeeded in storming the town?
Answer: In September 1343

Problem: A large number of minor nobles also joined the Crusade and before long, according to Arnold von Lübeck in his Arnoldi Chronica Slavorum, a powerful military host of 60,000, including 7,000 German knights, was on its way. A contemporary chronicler gave a lower estimate of 4,000 knights and an unknown amount of infantry. German historian Claudia Naumann suggested in 1994 that the Crusade had 16,000 men, including 3,000 knights.Bretislaus III, Duke of Bohemia had agreed to join the Crusade at the Diet in Worms on December 1195, and planned to do so, until he fell ill and died on 15 or 19 June 1197. In March 1197 Henry proceeded to the Kingdom of Sicily. The crusaders embarked for Acre, while the emperor first had to suppress an armed revolt in Catania. A force of 3,000 Saxon and Rhenish troops in 44 ships under Count Palatine Henry V and Archbishop Hartwig of Bremen sailed from northern Germany and arrived in Messina in August, where they merged with the emperor's troops and sailed to the Eastern Mediterranean. Still in Sicily, out for hunting near Fiumedinisi in August, Emperor Henry fell ill with chills, possibly from malaria. He died on September 28 before he could set sail for the Holy Land.

How many of the 60,000 troops were not German knights?
Answer: 53000
