The District of Oregon was a Union Army command department formed during the American Civil War.
The District of Oregon was part of the independent Department of the Pacific reconstituted by consolidating the Departments of California and Oregon, which was created on January 15, 1861 when the Army was reorganized. The district was created the same day, and comprised the same territory as the former Department of Oregon, the state of Oregon (except for the areas of the Rogue River and Umpqua River in Southern Oregon) and Washington Territory, with headquarters at Fort Vancouver in Washington Territory.
On March 3, 1865 the district included Idaho Territory after it was formed from the eastern part of Washington Territory. On March 14, 1865, the District of Oregon was extended to include the entire state of Oregon. [1]
On July 27, 1865 the Military Division of the Pacific was created under Major General Henry W. Halleck, replacing the Department of the Pacific. It consisted of the Department of the Columbia replacing the District of Oregon and the Department of California. George Wright, now a U. S. Army Brigadier General, was assigned to command the new Department of the Columbia. [2]
The Snake War (1864–1868) was an irregular war fought by the United States of America against the "Snake Indians," the settlers' term for Northern Paiute, Bannock and Western Shoshone bands who lived along the Snake River. Fighting took place in the states of Oregon, Nevada, and California, and in Idaho Territory. Total casualties from both sides of the conflict numbered 1,762 dead, wounded, or captured.
The Department of the Pacific or Pacific Department was a major command (Department) of the United States Army from 1853 to 1858. It replaced the Pacific Division, and was itself replaced by the Department of California and the Department of Oregon.
The First Regiment Oregon volunteer Cavalry was a volunteer regiment in United States service Union army that was formed in response to the American Civil War. With men recruited in Oregon and some recruited in surrounding states, the regiment primarily served to protect the state of Oregon and surrounding territories during the American Civil War.
The Pacific coast theater of the American Civil War consists of major military operations in the United States on the Pacific Ocean and in the states and Territories west of the Continental Divide. The theater was encompassed by the Department of the Pacific that included the states of California, Oregon, and Nevada, the territories of Washington, Utah, and later Idaho.
The 4th California Infantry was a volunteer infantry regiment recruited from northern California during the American Civil War. It was organized at Sacramento, Placerville, and Auburn in September and October 1861.
The Department of the Missouri was a command echelon of the United States Army in the 19th century and a sub division of the Military Division of the Missouri that functioned through the Indian Wars.
The history of Idaho in the American Civil War is atypical, as the territory was far from the battlefields.

Organized at San Francisco and Carson City September 2, 1861, to December 30, 1862, and attached to Department of the Pacific. The regiment was first assembled at the Presidio, San Francisco, and after completing its organization, five companies were sent to Oregon and Washington Territory, to relieve the regular troops, and two companies were sent to Santa Barbara. The troops of this regiment sent to Oregon were afterwards returned to California. It was mustered out during the month of October, 1864.
During the American Civil War in the early 1860s, the District of Utah was a subordinate district of the U.S. Army's Department of the Pacific. The district was composed of territorial areas that later became parts of the modern U.S. states of Idaho, Nevada, and Utah.

The role of Washington Territory in the American Civil War is atypical, as the territory was the most remote from the main battlefields of the conflict. The territory raised a small number of volunteers for the Union Army, who did not fight against the Confederate States Army but instead maintained defensive positions against possible foreign naval or land attacks. Although the Indian Wars in Washington were recent, there were no Indian hostilities within the area of modern Washington, unlike the rest of the western states and territories, during the Civil War. At the start of the American Civil War, modern-day Washington was part of the Washington Territory. On March 3, 1863, the Idaho Territory was formed from that territory, consisting of the entirety of modern-day Idaho, Montana, and all but southwest Wyoming, leaving the modern-day Washington as Washington Territory.
At the outbreak of the American Civil War, Oregon had no organised militia and had sold most of the equipment bought for the Rogue River Wars. The state's governor, John Whiteaker, was pro-slavery and opposed to Oregon's involvement in the conflict. As such, it was only in late 1862 with a new governor that the state raised any troops: the 1st Oregon Cavalry served until June 1865.
The Department of the Northwest was an U.S. Army Department created on September 6, 1862, to put down the Sioux uprising in Minnesota. Major General John Pope was made commander of the Department. At the end of the Civil War the Department was redesignated the Department of Dakota.
