On the morning of June 21, 1935, at the Holmes-Eureka lumber mill in Eureka, a six-week-old strike by Humboldt County lumber workers came to a violent end. A riot broke out when a crowd of more than 200 pickets clashed with police and vigilantes attempting to clear the front gate. Tear gas, then firearms were used against stone-throwing strikers, killing three and wounding at least seven. More than 100 people were arrested for rioting, resisting an officer, and battery.
