The day the first African-Americans arrived to swim, a crowd gathered with knives, bricks, and bats. They set upon the black children who had come to swim, forcing them to walk a gauntlet, striking and taunting them. The mob grew to five thousand people, who chased after any black person they saw approaching the park—children on bicycles, a man stepping off a streetcar, a truck stalled in traffic, a black man on a porch at a house next to the park. They kicked him as he lay on the ground, limp and bleeding.
