The day before the massacre, 25 February, the Weekly Humboldt Times wrote: "The Indians are still killing stock of the settlers in the back country and will continue to do so until they are driven from that section, or exterminated"; meanwhile prominent local residents had already formed a vigilante committee to deal with the problem, and were sworn to never reveal their membership.
For several days before the massacre, World Renewal ceremonies were being held at the village of Tuluwat, on Indian Island, less than a mile offshore from Eureka in Humboldt Bay. Up to 250 Wiyot participated in the ceremonies. The leader of the Humboldt Bay Wiyots was Captain Jim. He organized and led the ceremony to start a new year.
The Wiyot people were decimated. They were corralled at Fort Humboldt for protection. Survivors were herded mostly to Round Valley, established as an Indian reservation within California. They kept escaping and returning to their homeland.
By 1850, there were about 2000 Wiyot and Karok people living within this area. After 1860, there was an estimated 200 people left. By 1910 there were fewer than 100 full blood Wiyot people living within Wiyot territory. This rapid decline in population was caused by disease, slavery, target practice, protection, being herded from place to place (survivors' descendants describe this as "death marches"), and massacres. www.wikipedia.com
