From The Warmth of Other Suns, by Isabel Wilkerson:
In the spring of 1919, a colored soldier named Wilbur Little returned home to Blakely, Georgia, after a tour of duty in World War I. A band of white men saw him at the train station in his uniform. They ordered him to take it off and walk home in his underwear. He refused. Soon anonymous notes were warning him to leave town if he wanted to wear his uniform. Days later, a mob attacked him as he greeted friends congratulating him on his achievements. He was found beaten to death on the outskirts of town. He was wearing his uniform. He had survived the war only to be killed at home. Cases like that were cause enough for some men to go north.
