there were at least 100,000 blacks, about 50,000 indians (my ancestor was one of them) & about 40,000 latinos (mostly Mexican or Cuban nationality)that served the CSA.
the vast majority of "non-white" CSA veterans were either in state military formations, in "privately raised" formations OR partisan rangers.
Oh yeah? Well there were at least 500,000 blacks, 200,000 Indains, 310,000 Latinos, 110,000 Chinese, 78,000 Japanese, 29,930 Koreans, 11,310 Eskimos, and 1 native Hawaiian islander in the Union army.
