A Connecticut Yankee in King Arthur's Court

This story was written by Mark Twain over a century ago. It is the tale of an American man, Hank Morgan, that finds himself teleported back in time to King Arthur's domain n the sixteenth century. He is captured by an assailant and brought to the castle of king author as a prisoner and to be executed. His exotic clothing causes much attention among people. When he is thrown into prison he pretends he is a wizard and escapes sure death by coincidentally claiming that the solar eclipse is his doing. He strikes fear into the hearts of the entire kingdom and he is given money and power. Dubious people like the wizard Merlin begin to doubt his powers but the Yankee blows up his tower with blasting powder and pretends it was by magical forces. Now there is not a man in the land that could question his power and authority.
The Yankee was a gun factory manager and was use to commanding and demanding workers. I have a feeling that in the future chapters of the book that he will use his superior intelligence and knowledge to make some modernizations. Since he was able to make blasting power i see that he might be able to craft weaponry such as guns and cannons for the king. If he does however, and the book has any realism to it, he will change the future and he might not ever exist. It also said in the prologue that he was knocked out in a brawl before he travels into the past. Before this he is explaining that a bullet hole through a suit of chainmail was his doing. This would definitely reinforce my believe that he will bring the firearm into the past. Overall the story is a very interesting read and I really am interested in what feats Hank can accomplish.
