In the early 1930s, the International Longshoremen's Association, led by San Francisco-based Harry Bridges, tried to unionize all West Coast dockworkers to improve pay and working conditions. In 1934, after employers refused to recognize the union, West Coast longshoremen went out on strike for 98 days, seriously disrupting trade. At Seattle's Smith Cove, picketing strikers blocked access to the piers and tried to prevent ships from being loaded and unloaded. The mayor called out the police to curb periodic violence.

Strikers and sympathizers had stormed Seattle's police headquarters after police raids on Communist and radical unions began on July 18. When the men retreated to Smith Cove to join the picketers, Mayor Charles Smith led 300 policemen to the area armed with tear gas and submachine guns. Injuries were heavy on both sides, but no shots were fired.

This image shows a group of strikers standing next to a locomotive at Pier 40 at Smith Cove. The strikers were attempting to prevent cargo from being unloaded by nonunion workers and the train’s arrival provoked a confrontation between the strikers and the police. After seeing that the locomotive was pulling no cargo, the strikers allowed it to leave.
