 The men in the Hamburg Company militia were entirely black and mostly freedmen.A white supremacist group called the Red Shirts, led by Benjamin Tillman, who later went on serve a 24-year career in the United States Senate and whose term was marked by enacting racist legislation, instigated confrontations with the black citizens by claiming that said freedmen intentionally blocked passage of public roads and denied passage to any white man.Alternate sources say that a carriage of white men intentionally drove up against the head of the column to cause a civil disturbance.
