Cleve Jordan of Greenwood, Sam Block and others like James Bevel of Itta Bena, Amzie Moore of Cleveland and Fannie Lou Hamer of Ruleville, were able to mobilize existing churches and civic organizations throughout the county and the Mississippi Delta, and blacks began to attempt to register in larger numbers. The reaction by local whites was violent. In Greenwood, a local SNCC office was attacked by an armed mob. Homes and businesses were burned. Bob Moses and Randolph Blackwell were shot at while traveling in a car. Worker Jimmie Travis was seriously hurt in the attack. Protestors and marchers were attacked by police dogs.
