Explanation:
Tecumseh's plan was to unite all the Indians and oppose forced relocation by the Americans. Tecumseh got as far as to start building a settlement for Indians and started uniting the Indians with the help of his brother, the Prophet. However, he was stopped when General Harrison and his troops destroyed Prophetstown (the settlement for the Indians) and defeated Tecumseh's band of warriors. Tecumseh eventually died in a military camp.
The significance of the battle of Tippecanoe is that it was the end of his dream of a Native American Confederacy.
B.
Hitler's main reason for starting World War II was the following:
He wanted to unite the German people
He wanted to expand the land of Germany to feed more people (this is why he demanded Danzig from Poland)
Having more farmland during a war would allow for a larger capacity to produce food to feed the army. As the infantry is focused on the battle, things like food and other essential commodities increase in their intrinsic value because of what it represents, in that food gives energy to troops and the troops need energy to fight and win the war and/or battles. Napoleon and Frederick the Great are both attributed with saying "An army marches on its belly". Meaning fighting needs fuel and that fuel for soldiers is food, thus the importance of having a significant amount of farmland.
