Third Shinobi World War

Not much has been mentioned about the Third Great Shinobi War. ,. Also, in the Manga, the "Kakashi Gaiden" took place within the Third War.

During the Third Great Shinobi War, passed on Kakashi Gaiden arc, it can be noticed a big "celebrity", who took a big role for Konoha in the war. Konoha's Yellow Flash, or Minato Namikaze, or Fourth Hokage, had a flee-on-sight order. Every shinobi who didn't want to die was ordered to flee for the furthest location possible.

A demonstration of his power is given when Minato appears in a battle field in an intense Konohagakure vs. Iwagakure and orders all Konoha shinobi to throw the kunai he had prepared. The next time he is seen is when Kakashi wakes up from a battle that would've been lost if Kakashi hadn't thrown one of those special Kunai Minato gave him previously. This scene suggests that, after easily winning the "K vs. I" battle, Minato had still time to teleport on to where Kakashi was and win that battle, using his Flying Thunder God Technique.
