While some detachments of the 1st Oregon Volunteer Infantry Regiment occasionally skirmished with hostile Native American bands, the regiment's main duties were much more mundane. Most companies spent their time in garrison duty at small posts in eastern Oregon, southeast Washington, and southern Idaho. They protected immigrant trails and escorted wagon trains from Fort Boise to the Willamette Valley. Two companies escorted survey parties, and another constructed a road in southwestern Oregon. While scouting sixteen miles from Camp Wright on the Selvies River, near present-day
Burns, Captain Loren L. Williams and a party of twenty Oregon infantrymen from Company H were ambushed by a band of hostile Native Americans. Williams and his troops fought a harrowing retreat back to Camp Wright, defending themselves for about fifteen hours before they reached safety. All along the way Native Americans fired from concealed positions. At one point, they even set a brush fire in the soldiers path to prevent them from escaping. Despite their continuous attacks, the Native Americans only wounded two soldiers. In his report, Williams stated that his long-range rifles killed fifteen Native Americans. He also stated that his superior weaponry was the only thing that prevented his party from being overrun. In the fall of 1865, Colonel Currey was planning a winter campaign against the Native Americans in eastern Oregon. To prepare, he sent detachments of the 1st Oregon Infantry along with Oregon cavalry units to Camp Alvord in the
Alvord Valley; Camp Polk near present-day
Sisters; Camp Currey near
Silver Lake; Camp Logan and Camp Colfax along the Boise Road east of
Canyon City; Camp Wallace; and Camp Lander near Fort Hall in the Idaho Territory. Detachment commanders were instructed to build winter quarters at their posts and prepare for a winter offensive. Winter provisions were to follow in supply wagons. However, the end of the Civil War in the east had freed up many regular officers for duty in the west, and as a result, Colonel Currey was released from duty in November 1865 along with the men from companies C, D, and E. Lieutenant Colonel Drake was released from service in December, so the planned winter campaign never got started. ==Disbanding==
