Funny enough, the Revolutionary War has the highest rate of racially integrated soldiers until the Vietnam war.

No African-Americans would be admitted to the US Army after the end of the Revolutionary War until the US Civil War some 90 years later, and there wouldn’t be integrated Army formations again until 1948. (the US Navy continued accepting African-American sailors through this entire period)

Sometimes, the only thing worse than the past being shitty is when it starts out promising, and then goes downhill.
