I'm looking at a copy of "Black Valor - Buffalo Soldiers and the Medal of Honor, 1870-1898", by Frank N. Schubert, c.1997. I knew had some of his work in my small library.
I asked the question because it appeared that your original post trailed off with an incomplete phrase that led me to believe there was more to it. Sometimes in our zeal to help others we forget to protect other's work. Even manuscripts of speeches are protected works so that with or without permission to use, the bare minimum in protection is to cite the source. As important we don't want to put Afrigeneas in question.
On the subject matter, an appropriate observation. As I mentioned in another article, for the most part, Buffalo Soldiers were "enemies" of Native people and their life ways.
The romanticism of the Buffalo Soldiers to some Native Americans often has the same affect as romanticism of the KKK in the old movie "Birth of a Nation” (D.W. Griffith 1915) has on African Americans.
In African American history we recognize the Buffalo Soldiers and other stalwarts largely to counteract one prevailing historically racist assertion that Blacks in general were lazy, shiftless, liars, thieves and cowards. As far as soldiering, this attitude continued on to the Tuskegee Airmen and beyond. People have done interesting things to try and prove their worthiness as Americans, Native Americans fighting FOR Andrew Jackson is a similar example, but the final observation for me is that people don't like to be reminded of their defeat, especially if the survivors are still living in desperate conditions.
