The Cascades Massacre was an attempt to repel white settlers who had usurped the land of Native Americans at the Cascades Rapids that occurred on March 26, 1856. The native defenders included warriors from the Yakama, Klickitat, and Cascades tribes. Fourteen settlers and three soldiers died in the attack, the most losses for the invading forces during the Yakima War. U.S. reinforcements arrived on the following day to drive out the original inhabitants. The Yakama people were able to evade prosecution, but nine Cascades, including Chief Chenoweth, were charged and executed for “treason”.
