Yagyu Munenori

"Yagyu Munenori, mentioned earlier, was a high-spirited swordsman of the seventeenth and eighteenth centuries with a true love for the battlefield style of fencing. In his view, the new "wait and see" style was becoming too popular, and the samurai who trained in it were becoming soft and confusing reality and fantasy. Having obtained permission from the shogun to test his skills against this style, he went to the Yoshiwara area of Edo and deliberately provoked a group of seven samurai by spitting on them. In the fight that followed, Yagyu killed two outright, and severed the arms of two others. Three ran for their lives."
