Interesting footnote: George Patton, grandson of a Confederate officer and a Southerner by birth and temperament,without hesitation integrated his Third army units to maintain combat efficiency.
Patton had two Grandfathers who were Confederate veterans. One a general and the other a colonel. One died at New Market.
Patton was from California and he did not integrate his army. It actually would have been a big mess if he tried.
patton wanted to keep going and deal with the russians right there. we wouldn’t let him.
Raised in California, however.
