Problem: Some hint of Cnut's childhood can be found in the Flateyjarbók, a 13th-century source that says he was taught his soldiery by the chieftain Thorkell the Tall, brother to Sigurd, Jarl of mythical Jomsborg, and the legendary Joms, at their Viking stronghold on the island of Wollin, off the coast of Pomerania. His date of birth, like his mother's name, is unknown. Contemporary works such as the Chronicon and the Encomium Emmae, do not mention this. Even so, in a Knútsdrápa by the skald Óttarr svarti, there is a statement that Cnut was "of no great age" when he first went to war. It also mentions a battle identifiable with Sweyn Forkbeard's invasion of England and attack on the city of Norwich, in 1003/04, after the St. Brice's Day massacre of Danes by the English, in 1002. If Cnut indeed accompanied this expedition, his birthdate may be near 990, or even 980. If not, and if the skald's poetic verse references another assault, such as Forkbeard's conquest of England in 1013/14, it may even suggest a birth date nearer 1000. There is a passage of the Encomiast  with a reference to the force Cnut led in his English conquest of 1015/16. Here  it says all the Vikings were of "mature age" under Cnut "the king". A description of Cnut appears in the 13th-century Knýtlinga saga:

Problem: After the fall of France in June 1940, the Free French had only a 3,000 strong contingent in Britain, growing to 7,000 by the end of the year, Poland evacuated around 19,000 to 35,000. By the end of 1940, I Corps in the West (Poland) numbered about 14,000; Polish forces in the Middle East, about 3,000; this does not count the Polish air crews (numbering at least 4,000) and the Polish Navy personnel. After the fall of France, the French forces lagged behind the Polish in numbers. It was only after D-Day and the liberation of the French mainland that French forces swelled to 550,000, outnumbering the Polish Army in the West, but not the combined West, East and partisan forces. Until 1944, Polish forces also outnumbered the French. In 1942, the French resistance numbered about 10,000, (the size of Polish resistance is discussed in note b below) and in 1943, the Free French numbered about 70,000. With the entrance of Soviet Union into the war in June 1941, Poland returned to being the third biggest Ally again, and with the entry of United States in December 41, the fourth. However, the Japanese involvement also marked the connection of the European and African theaters to Second Sino-Japanese War, and estimates cited above ignore China, whose armies totaled about two million by the end of the war. Thus for about a year, Poland could be seen as the second biggest ally, after Britain. It was then superseded by China, the Soviet Union and the United States. Counting China, from the end of 1941, Poland was the 5th biggest ally. Near the end of the war, Polish contribution, in terms of numbers was matched or surpassed by that of France.

Problem: The first reinforcement to the Teutonic forces arrived in early 1261, but was wiped out on January 21, 1261 by Herkus Monte in the Battle of Pokarwis. In January 1262 reinforcements arrived from the Rhineland, led by Wilhelm VII, Duke of Jülich, who was obliged by Pope Alexander IV to fulfil his crusader duties in Prussia. This army broke the Siege of Königsberg but as soon as the army returned home, the Sambians resumed the siege and were reinforced by Herkus Monte and his Natangians. Herkus was later injured and the Natangians retreated, leaving the Sambians unable to stop supplies reaching the castle and the siege eventually failed. Prussians were more successful capturing castles deeper into the Prussian territory , and the Knights were left only with strongholds in Balga, Elbing, Culm, Thorn, and Königsberg. Most castles fell in 1262-1263, and Bartenstein fell in 1264. The Prussians destroyed captured forts instead of using them for their own defence, so the end of successful sieges meant that large Prussian forces did not have to stay near their home and were then free to operate in other parts of Prussia, raiding the Culmerland and Kuyavia. A recovered Herkus Monte raided Culmerland with a large force and took many prisoners in 1263. On his way back to Natangia, Herkus and his men were confronted by a contingent of their enemies. In the Battle of Löbau that ensued, Prussians killed forty knights, including the Master and the Marshal. The Prussians also received help from Lithuanians and Sudovians. In summer of 1262 Treniota and Shvarn attacked Masovia, killing Duke Siemowit I, and raided Culmerland, provoking Pogesanians to join the uprising. However, assassination of Mindaugas and subsequent dynastic fights prevented Lithuanians from further campaigns. Skalmantas, leader of Sudovians, raided Culm  in 1263 and in 1265.
