How they got screwed:
The Free French Army fought victory after bloody victory right up to Paris' doorstep, and they were ready and willing to march in and liberate the capital, with a little help from their American and British allies. Unfortunately, their allies said, "Hell no. Not with all those darkies."
This was a time in history where blacks and whites were still segregated in the American military and forbidden from fighting together. The Allies had an image to uphold, after all -- better for the people to watch Paris liberated by square-jawed, chiseled Aryan superheroes than a ragtag bunch of African natives and Muslims. Before de Gaulle was granted permission by America to take back his own country, he had to scramble to find enough white people to replace anyone in his army who failed the melanin test.
Whoa now. Can't have this guy in battle-scarred Nazi-held Paris.
Of course, that had been de Gaulle's entire problem in the first place. His ultimate solution was to borrow a whole bunch of Spanish soldiers, dress them in berets and pencil mustaches and hope nobody would notice. In the meantime, the Africans were sent home without any of the glory, but at least they enjoyed the benefits of having served -- that is, until 1959, when the French inexplicably cut off their military pensions and tried to cover up their role in the war.
