On the afternoon and evening of April 8, the mood in Wilmington became angrier. A group of African-American men who called themselves the Goon Squad and patrolled the city's streets attempting to prevent gang violence were assaulted by teens throwing rocks. Local ministers and representatives from the NAACP urged calm to no avail. Governor Charles Terry declared a state of emergency in the city and activated over 1,000 National Guard troops, but after the 10:30 PM curfew passed, it appeared that the worst was over.
Over the next two nights, however, rioting spread through West Center City. Historians differ on the extent of the damage caused by rioting. Roughly fifteen buildings--some of which were slated for demolition--were destroyed by arson. Several dozen people were injured, and nearly 160 people were arrested on the April 9 and 10.
On April 9, Governor Terry ordered 2,800 National Guardsmen to Wilmington to maintain order, and many residents expected that the troops would be removed once the rioting ended. Though the rioting in Wilmington was short-lived and led to comparatively minimal damage, the governor announced his plans to keep the National Guard in the city until it was safe. The troops remained in Wilmington for nine months--the longest occupation of an American city since the Civil War.
Wilmington of 1968 was a divided city before the occupation. The construction of I-95 through the city led to the destruction of numerous inner city neighborhoods and led to lingering bad blood. There was two days of race-related riots in July of 1967. But the prolonged occupation of the city in 1968-69 heightened the distrust that many residents felt toward the government. Many working-class families left West Center City and other inner city neighborhoods in the aftermath, and many businesses and white families fled to the suburbs. That part of Wilmington has never completely rebounded from the events of 1968.
