Progressive Historians has a great post about a Ku Klux Klan chapter in North Carolina who, in 1958, decided to pick on a group of Lumbee Indians. This turned out to be a really bad idea:
Instead of cowering, the Lumbees had assembled about a mile away. Small groups of armed Lumbee indians, about 500 in total, fanned out across the highway and began to encircle the Klansmen.
As the song finished and the rally was to begin, Sanford Locklear walked up to Cole and began arguing with him. Words became shoves and tempers rose. Neill Lowery had seen enough. He leveled his shotgun at his hip and blasted out the floodlight. The field went dark.
The Lumbees began firing into the air and yelling their warhoops as they charged the field. The nerve of the Klansmen broke and they fell into complete panic.
The Klansmen dropped their guns and scrambled for their cars. Some had brought their wives and children with them, who wailed in fear as dark-faced Lumbee milled around their cars and pointed flashlights at them.
James Cole, the Grand Dragon himself, was in such a panic that he ran into a nearby swamp, abandoning his wife and "white womanhood" in the process. Cole's wife, Carolyn, also in a panic, drove her car into a ditch. After a few minutes several Lumbee helped push her car back onto the road.
