The Battle of the Overpass was a key event in the history of American labor relations, occurring on May 26, 1937, at the Ford Motor Company’s River Rouge Plant in Dearborn, Michigan. This event, marked by violence and a public relations disaster for Ford, highlighted the intense struggle between labor unions and corporations over the right to unionize and organize workers in the 1930s.
Background
In the mid-1930s, the labor movement in the United States was gaining momentum, particularly in the automotive industry. The United Automobile Workers (UAW), formed in 1935 as part of the Congress of Industrial Organizations (CIO), sought to unionize workers in the automobile industry, demanding better wages, working conditions, and job security. Other major automakers, such as General Motors and Chrysler, had begun recognizing unions following strikes and negotiations, but Ford Motor Company remained staunchly anti-union.
Henry Ford, the founder of the company, was deeply opposed to labor unions. Ford believed in maintaining direct control over his workforce and feared that unions would disrupt his carefully crafted industrial system. He was also worried about the financial costs of collective bargaining. To enforce his anti-union stance, Ford relied heavily on his Service Department, a security force led by Harry Bennett. Bennett, a close associate of Ford, was a former boxer and street fighter known for using intimidation, threats, and violence to suppress union activities and maintain discipline among Ford’s workers.
Lead-Up to the Battle
By 1937, the UAW had already made some headway in organizing auto workers but had faced stiff resistance from Ford. The union’s leaders decided to take a bold step by distributing leaflets and pro-union literature to Ford workers at the company’s largest and most important factory—the River Rouge Plant. Located in Dearborn, this plant was a massive industrial complex, employing tens of thousands of workers and serving as the centrepiece of Ford’s manufacturing operations.

The UAW leaders, including prominent labour organizer Walter Reuther and Richard Frankensteen, chose to distribute materials near the plant’s Miller Road Overpass, which provided a pedestrian walkway into the factory. Their goal was to publicize the union’s goals, raise awareness among the workforce, and encourage workers to join the union.
The Battle: What Happened?

On May 26, 1937, Reuther, Frankensteen, and several other UAW leaders arrived at the River Rouge Plant with leaflets promoting union membership. They positioned themselves on the overpass, intending to engage with workers as they entered or left the plant during shift changes.
However, Ford’s Service Department, under Harry Bennett’s orders, was prepared to confront them. Bennett had stationed a group of armed security guards and company loyalists to deal with the union organizers. What followed was a violent and brutal confrontation:
Attack by Ford Security: As Reuther, Frankensteen, and others began distributing leaflets, they were approached by Ford’s security men, who launched a surprise attack. Without warning, the guards began beating the UAW leaders with fists, clubs, and brass knuckles. Reuther was specifically targeted, with guards pummelling him and attempting to throw him off the overpass.
Public Beating: The attacks were highly visible, taking place in broad daylight and in front of workers entering and leaving the factory. The UAW leaders were severely beaten, suffering numerous injuries. Frankensteen had his jacket pulled over his head while he was beaten, and Reuther was kicked and punched repeatedly.


Photographs and Media Coverage: Crucially, photographers from the press were present at the scene. One of the most significant outcomes of the event was the photographic evidence captured by James Kilpatrick, a Detroit News photographer. Kilpatrick’s images, which clearly showed the violent assault on Reuther and other union leaders, were published in newspapers nationwide, bringing widespread attention to the incident.

Public Outcry: The photographs caused an uproar. The brutality of the attack, combined with the visibility of the UAW leaders as public figures, made the incident a public relations disaster for Ford Motor Company. While Ford and his managers attempted to downplay the event, the images spoke for themselves, showing Ford’s security forces as thugs assaulting peaceful labor organizers.
Aftermath and Significance
The Battle of the Overpass was a turning point in labor relations, especially within the auto industry. The incident had several key consequences:
National Attention: The widespread media coverage drew national attention to the UAW’s efforts to unionize auto workers and the brutal methods Ford used to suppress union activities. Public sentiment began to shift in favor of the labor movement, particularly because of the visible brutality of the attack.
Labour Relations Act and Court Orders: After the Battle of the Overpass, the National Labor Relations Board (NLRB), which had been created under the Wagner Act (1935) to oversee labor disputes, became more involved. The Wagner Act guaranteed workers’ rights to organize and collectively bargain, and Ford’s violent actions were seen as a violation of these rights. The NLRB later ruled that Ford had engaged in unfair labor practices, though Ford continued to resist unionization for several more years.
Strengthening of the UAW: The publicity from the event significantly strengthened the UAW. The union gained sympathy from the public and further legitimacy in its fight to organize auto workers. The incident galvanized workers, especially those at Ford, who became increasingly aware of the need for a union to protect their interests.
Union Recognition at Ford: Despite the public relations disaster, Ford continued to resist the UAW for several more years. It wasn’t until 1941, after a successful strike and growing pressure from both the government and public opinion, that Ford finally agreed to recognize the UAW and allow unionization at its plants.
Symbol of Labor Struggle: The Battle of the Overpass became a symbol of the broader labor struggle in the United States during the 1930s. It was a defining moment in the fight for workers’ rights, underscoring the lengths to which powerful industrialists would go to prevent unionization, and the determination of labor organizers to fight for better conditions despite these challenges.
Legacy
The Battle of the Overpass is remembered as a key moment in American labor history, one that exposed the harsh realities of the conflict between workers and employers in the early 20th century. It demonstrated the power of the media to shape public opinion, as the photographs of the event played a crucial role in shifting the tide in favor of the labor movement.
The event is also a testament to the tenacity of labor leaders like Walter Reuther, who would go on to play a leading role in organizing the auto industry and later become a major figure in the American labor movement. It is a reminder of the hard-fought battles that led to the establishment of unions and labor rights that many workers benefit from today.
