Demonstrations by the CNAC resumed at the end of March, when a local movie theater expanded its discriminatory practices by relegating African-Americans to the back rows of the balcony instead of the entire balcony, as had been done previously. This escalation motivated leaders of both the CNAC and CIG to meet with city officials to discuss the desegregation of public accommodations, equal employment opportunities, and fair housing for African Americans, but their demands went unmet. In response, demonstrators marched through downtown Cambridge to protest the continuing segregation allowed in public venues, which ended with the arrest of Richardson and sixteen other demonstrators for "disorderly conduct." A boycott of white-owned businesses was then organized by the CNAC, with this pattern of protests, arrests, boycotts, and harassment continuing through April. CNAC demonstrations continued in mid-May, with many of them led by high school students Dwight Cromwell and Dinez White, both 15, who were later charged with "disorderly conduct" after being arrested while praying peacefully outside of a segregated facility. Cromwell and White were held without bail and eventually sentenced to indefinite incarceration in a state juvenile facility. Marches were organized by the CNAC on the nights of June 11 and June 12 to protest the sentences given to Cromwell and White. On June 13, a third march was organized downtown. On June 14, several white-owned businesses in the Second Ward - a predominately African-American section of town - were set on fire, and gunfire was exchanged between white and African-American citizens, resulting in casualties. Governor Tawes declared
martial law and deployed the
Maryland National Guard to Cambridge after the CNAC refused a year-long moratorium on protests. The guardsmen remained in the town for 25 days, from June 14 through July 8. Tensions further increased when 250 African-Americans organized a "freedom walk" to the Dorchester County Court House that evening and were met by a crowd of 700 whites. The two groups were kept apart and eventually dispersed by the
Maryland State Police. Cambridge remained quiet until 10 p.m., when two white men and a 12-year-old boy were wounded by shotgun fire near their homes and police brought eight African-American men in for questioning. In the early morning hours of July 12, two carloads of white men drove through the Second Ward, exchanging gunfire with African Americans. Police arrested five white men in their early 20s after the first exchange of gunfire in the African-American district. Three National Guardsmen in a civilian car were injured when a gunshot blast punctured their windshield during the second round of gunfire between whites and African Americans. Order was reestablished around 2 a.m. on July 12 and Major George E. Davidson of the Maryland State Police recommended to Governor Tawes that full martial law be reinstated. The Maryland National Guard was redeployed to Cambridge, where they would remain for the next year. Brigadier General George Gelston, assistant state adjutant general and commander of the troops, imposed a modified martial law that consisted of a 9 p.m. curfew, a ban on further racial demonstrations, and prohibitions of carrying firearms and selling liquor. == Events of 1967 ==
