    -Sō Yoshishige altered Hideyoshi’s message to soften the diplomatic blow, but the Sō clan leader sent a rough and indelicate subordinate, Yutani Yasuhiro, to deliver the message. Yasuhiro insulted the Korean hosts, leading to the Korean refusal to submit to Hideyoshi, which in turn led to Hideyoshi's fury and punishment.

  • What was the composition of Hideyoshi’s invasion force?

    -The invasion force consisted of 158,000 men, primarily made up of ashigaru, peasant foot soldiers armed with swords, spears, and bows. About one-third of the army was armed with arquebuses, an early form of firearm.

  • How did Admiral Yi Sun-shin contribute to the defense of Korea during the Imjin War?

  • How did the Japanese forces attempt to neutralize Admiral Yi Sun-shin?

    -The Japanese forces used a spy named Yojiro to trick the Korean court into believing that Konishi Yukinaga wanted to betray his rival, Kato Kiyomasa.
