Qualchan (died September 24, 1858) was a 19th-century Yakama chieftain who participated in the Yakima War with his uncle Kamiakin and other chieftains.
Shortly after the Walla Walla council in 1855, in which Yakama leaders warned the United States against further settlement of the area, Qualchan and five others killed six settlers on the Yakima River. On September 23, U.S. Indian Agent Andrew Bolon was murdered by a band of Yakama while traveling along The Dalles to discuss the incident with Kamiakin. Qualchan was accused of leading the group which attacked him, although historians such as A.J. Splawn insist Bolon's murder was carried out by Me-cheil, also a nephew of Kamiakin.
Becoming a wanted fugitive by U.S. authorities, he and his father Owhi participated in guerrilla warfare against the US Army for over three years. Qualchan would frequently attack prospectors, miners and others, selling their supplies to The Dalles and other settlements in exchange for weapons and calicos. During one skirmish in mid-March 1856, he and Chief Leschi led an attack against Connell's Prairie but were driven back by militiamen under Gilmore Hays.
According to Assistant Adjutant General W.W. Mackall, in a letter addressed to the Department of the Pacific at Fort Vancouver on June 18, 1858,
"Kamiakin and Qualchan, cannot longer be permitted to remain at large or in the country, they must be surrendered or driven away, and no accommodation should be made with any who will harbor them; let all know that asylum given to either of these troublesome Indians, will be considered in future as evidence of a hostile intention on the part of the tribe".
Following the Horse Camp Slaughter and encouragement from Spokane runners, Owhi visited Colonel George Wright at his camp on Latah Creek intending to negotiate peace. During the meeting he was seized and put in irons. Wright told him that if his son didn't surrender within four days, Owhi was to be hanged. Despite Wright stating his intention to send Qualchan a message demanding he come to the camp, Native witnesses deny one was ever sent.
Qualchan regardless appeared at the tent of Wright soon enough, accompanied by his wife Whist-alks and brother Lo-Kout. It has been speculated that Qualchan may have been unaware that his father had been taken prisoner and instead had been sent by Kamiakin to determine from Wright the treatment the Yakama would receive if they surrendered. Some say he was captured in a brief gun battle while his wife and brother managed to escape. Qualchan's sister Mary Moses said Lo-kout and Qualchan's wife were captured, but released when the Spokane Indians assured the soldiers that they were no relation of Qualchan. The only record of the meeting exists in a report made by Colonel Wright who wrote "Qualchan came to see me at 9 o'clock, at 9:15 he was hung". Later records claim Qualchan cursed Kamiakin before being killed, though this was disputed by his family members alive at the time. His body was made nude after the garments were taken by the executors, who put the corpse partially covered in a shoal. His father was shot several days later attempting to escape from the camp, his saddle given to later Surgeon General Joseph Barnes.
