I don't get what the picture has to do with the American Civil War, but plantation owners in Trinidad, Guyana, and Surinam were all too wiling to import Muslims and Hindus from India and the East Indies as field labor after emancipation came.
Who's to say that an independent Confederacy wouldn't have done the same thing? Even in defeat, Southern planters imported Chinese indentured labor. In victory, who can say what they would have done?
So, no. You can't blame the Yankees for that.
