The hit on the head that sends Hank Morgan back through 13 centuries does not affect his natural resourcefulness. Using his knowledge of an upcoming eclipse, Hank escapes a death sentence, and secures an important position at court. Gradually, he introduces 19th century technology and soon has an easy life. He becomes "The Boss" of the Kingdom, second only to the King. That does not stop him from making a disparaging remark which touches off an incredible series of events. Twain weaves many of the well-known Arthurian characters into his story, and includes a pitched battle between Morgan's men and the nobility. This is Mark Twain at his best.
