Passage: On March 7, 1965, acting on Bevel's plan, Hosea Williams of the SCLC and John Lewis of SNCC led a march of 600 people to walk the 54 miles (87 km) from Selma to the state capital in Montgomery. Six blocks into the march, at the Edmund Pettus Bridge where the marchers left the city and moved into the county, state troopers and local county law enforcement, some mounted on horseback, attacked the peaceful demonstrators with billy clubs, tear gas, rubber tubes wrapped in barbed wire, and bull whips. They drove the marchers back into Selma. Lewis was knocked unconscious and dragged to safety. At least 16 other marchers were hospitalized. Among those gassed and beaten was Amelia Boynton Robinson, who was at the center of civil rights activity at the time.
