On Sunday morning, October 28, 1855, Indians of the Muckleshoot and Klickitat tribes under Nelson and Kanasket raid farms between present-day Kent and Auburn and kill nine settlers. These attacks follow skirmishing in Pierce County between Nisquallys and Territorial volunteers sent to arrest the Nisqually chiefs Leschi (1808-1858) and Quiemuth, who refused to remove to treaty reservations.
Nisqually-Suquamish Chief Kitsap (d. 1858; not to be confused with the hostile Klickitat Chief Kitsap) and other sympathetic Indians advised settlers to flee. A. L. Porter narrowly escaped a raid on his White River cabin on September 27, 1855. He spread the alarm to other settlers, who retreated to Seattle's blockhouse. But Acting Territorial Governor Charles H. Mason (1830-1859) had assured settlers that there was no danger and settlers returned to their claims.
On October 22, 1855, the Nisqually chiefs met with Mason and they affirmed their position that they could not and would not live on the reservations provided in the Medicine Creek Treaty they had signed the prior December. A settler then wrote to Mason alleging that Leschi was organizing Indians to war against the whites. Reports and rumors of Indian attacks spread throughout the territory. Mason ordered Territorial volunteer Captain Charles H. Eaton and his 18 Mounted Rangers to seize Leschi and Quiemuth. The Nisquallys saw this as a hostile act and fled on October 25. Leschi joined warriors from the Klickitat and Muckleshoot tribes who had gathered after fighting broke out between the Yakamas and U.S. Army troops east of the Cascades.
Early on Sunday morning, raiders broke down cabin doors and assaulted settlers. The victims of the White River raid were William H. Brannan, wife and child; Harry N. Jones, wife, and hired hand Enos Cooper; and George E. King, wife, and a child. A second King child, George, was abducted but returned to Fort Steilacoom the following spring. Three Jones children were spared on the order of Muckleshoot Chief Nelson, and they carried news of the attack to Seattle.
That same morning in Thurston County, a settler named Clark was ambushed while attending church services at Eaton Schoolhouse. Other settlers fought off the attack.
Many innocent Indians later suffered for the incident when the territorial government offered friendly tribes, notably the Snoqualmies, a bounty for the severed heads of suspected renegades. Tensions in King County intensified over the following weeks. Seattle Indian Agent Dr. David S. Maynard (1808-1873) arranged for the quick relocation of local Indians to the new Suquamish reservation on the western shore of Puget Sound across from Seattle.
