The Battle of the Overpass was an attack by Ford Motor Company against the United Auto Workers (UAW) on May 26, 1937, at the River Rouge complex in Dearborn, Michigan. The UAW had recently organized workers at Ford's competitors, and planned to hand out leaflets at an overpass leading to the plant's main gate in view of many of the 90,000 employees. Before the UAW organizers could begin, they were attacked by Ford's "quasi-military" security service and the Dearborn police. In the aftermath, Ford Motor Company attempted to control the narrative by destroying news photographs onsite. The surviving photographs were published nationally as evidence of Ford's brutality, helping to turn public perception in favor of the union. The incident had been preceded five years earlier by the 1932 Ford Hunger March, in which hunger marchers were attacked with gunfire from the Miller Road pedestrian overpasses. The site of that attack remained an entrance to the Rouge plant, and the overpass bears the logo of the United Auto Workers in addition to Ford's.
