The West Indian recruits are well documented and known by WW2 re-enactors and how brave they were. The Nazis saw them as racially inferior, as witnessed at Wereth in Belgium, during what became known as, The Battle of the Bulge.
African/American troops who were already racially segregated back then, and the Nazis who captured those soldiers, saw fit to torture and slaughter them.
There's no evidence to suggest that the West Indian soldiers got wind of this, but had they been captured their fate would almost certainly have been similar to those of their American cousins. Brave men indeed.
My very good friend, who served 22 years in the army, told me that if you ask any soldier about his feelings towards someone in his ranks of a different colour, you will get the reply that, Brothers-in-Arms are just that. Race, creed, politics and religion, never separates them.
