Yes. When I said men I was referring to males. Gentlemen if that clarifies it further. Though there are a few accounts of women (females/ladies) who were camp followers contributing in extenuating circumstances in combat roles.
and what was the color of their skin?
Depended on the person. It was majority Caucasian men, who also made up the majority of the free male population. But as alluded to in the previous comment of mine, Freemen like Mr. Salem joined the fray. Native Americans also fought in some cases on the side of the Patriots, though they mostly sided with the British due to their strong ties to the Iroquois Confederacy.
