In the fall and winter of 1855–1856, hostilities broke out between Indians urging resistance and the White American settlers, primarily over discontent with the Point Elliott Treaty and other treaties enacted by Governor Isaac Stevens in 1854–1855. These hostilities climaxed in the "Battle of Seattle" in January 1856. Hostile Indians including Yakamas and Klickiats from east of the Cascade mountains assembled on Lake Washington, led by Yakama Chief Kamiakim and "si'ab" Lescay (Chief Leschi), to stage an attack on Seattle. Many friendly Indians took refuge in town, including Cheshiahud. The settlers retreated to a blockhouse on Elliott Bay at the end of Cherry Street. Although the battle lasted only one day and had only two known fatalities, nearly every building in King County outside the village of Seattle was burned, including the cabin and outbuildings of John Harvey and E. A. Clark, and the dam on the Black River that had raised Lake Washington—the White population was in the hundreds at this time.
