One of the members of that entourage (to place the flag on Mt. Sarubuchi) was a Pima Indian from a reservation in Arizona. His name was Ira Hayes. There is a song written about him. "The Ballad of Ira Hayes".

Aggie, If you see Ramblin' Jack, ask him about it. I bet he will sing it for you. It was written by Richard Farina. At the time, he was married to the sister of Joan Baez, Mimi. He was later killed in a traffic accident. He also wrote a book titled "Been down so long, it looks like up to me". Long out of print, but a good read of how it was in the '60's.
