The Elaine massacre occurred on September 30 – October 2, 1919, at Hoop Spur in the vicinity of Elaine in rural Phillips County, Arkansas where African Americans were organizing against peonage and abuses in tenant farming. As many as several hundred African Americans and five white men were killed. Estimates of deaths made in the immediate aftermath of the Elaine Massacre by eyewitnesses range from 50 to "more than a hundred". Walter Francis White, an NAACP attorney who visited Elaine shortly after the incident, stated "... twenty-five Negroes killed, although some place the Negro fatalities as high as one hundred". More recent estimates in the 21st century of the number of black people killed during this violence are higher than estimates provided by the eyewitnesses, and have ranged into the hundreds. The white mobs were aided by federal troops and local terrorist organizations. Gov. Brough led a contingent of 583 US soldiers from Camp Pike, with a 12-gun machine gun battalion.
