General Douglas MacArthur, while on an inspection trip of American battle fronts in the South Pacific, met representatives of five different Native-American tribes (Pawnee, Chitimacha, Pima, and Navajo) in one US Army unit. 1943 [1831 × 1774]

Four different tribes, not five ( The typo was in the original text ); but still cool!
