Burnham would have sent the Carib to Cuba like how he sent his son in law Van West to Cuba.
Do you know that Cuban students mounted a protest when they saw how Caribbean and other students from democratic nations were treated? Not forced to eat rotten fish?
Of course Fidel sentenced them to cut cane in the hot sun as punishment. And they weren't paid. The irony that this was what the old Cuban plantocracy did wasn't anything that Fidel spent a second thinking about. Of course his ancestors were slave owners and Fidel grew up on an estate where the Haitian workers were treated like cattle.
