The Pacific Coast Theater of the American Civil War was the 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 operations of Union volunteer troop detachments, primarily from California, some from Oregon, and a few companies from Washington Territory, were directed mostly against Indians in the theater. Union and Confederate regular forces did not meet directly within the Pacific Department except in New Mexico Territory, however operations were directed against Confederate irregulars in California and strong garrisons were placed in Southern California and southern New Mexico Territory to control the region which had strong secessionist sympathies. Although the Union and Confederate armies did not directly meet (except in New Mexico Territory), Confederate States Navy warships operated in the Pacific Ocean, but the naval operations did not succeed in interrupting commerce to the Eastern United States. The last of these commerce raiders, the CSS Shenandoah, fired the last shot of the War in the Bering Sea off the coast of Alaska. Attempts by the Confederacy to buy or seize ships for commerce raiding on the West Coast were thwarted by alert Union officials and the Pacific Squadron.
The Pacific Northwest is a region in western North America bounded by the Pacific Ocean to the west and, loosely, by the Rocky Mountains on the east. Though no universally agreed upon boundary exists, a common conception includes the U.S. states of Oregon, Washington, and the Canadian province of British Columbia. Broader conceptions reach north into Alaska and Yukon, south into the coastal and mountainous regions of Northern California, and east into Idaho and western Montana, western Wyoming, and western Alberta, to the Continental Divide. Narrower conceptions may be limited to the Northwestern U.S. or to the coastal areas west of the Cascade and Coast mountains. The variety of definitions can be attributed to partially overlapping commonalities of the region's history, geography, society, and other factors.
The Northwest Coast is the coastal regions of the Pacific Northwest and the Northwest Plateau (also commonly known as "The Interior" in British Columbia and the Inland Empire in the United States) is the inland regions. The term "Pacific Northwest" should not be confused with the Northwest Territory (also known as the Great Northwest, a historical term in the United States) or the Northwest Territories of Canada.
West Coast or Pacific Coast are terms for the westernmost coastal states of the United States, usually California, Oregon, and Washington. More specifically, the term refers to an area defined on the east by the Cascade Range, Sierra Nevada and Mojave Desert and on the west by the Pacific Ocean. The U.S. Census groups the five states of California, Oregon, Washington, Alaska, and Hawaii together as the Pacific States division.
The American frontier comprises the geography, history, folklore, and cultural expression of life in the forward wave of American westward expansion that began with English colonial settlements in the early 17th century and ended with the admission of the last mainland territories as states in the early 20th century. Enormous popular attention in the media focuses on the Western United States in the second half of the nineteenth century, a period sometimes called the Old West, or the Wild West.
As defined by Hine and Faragher, "frontier history tells the story of the creation and defense of communities, the use of the land, the development of markets, and the formation of states." They explain, "It is a tale of conquest, but also one of survival, persistence, and the merging of peoples and cultures that gave birth and continuing life to America." Through treaties with foreign nations and native tribes, political compromise, military conquest, establishment of law and order, building farms, ranches and towns, marking trails and digging mines, and pulling in great migrations of foreigners, the United States expanded from coast to coast fulfilling the dreams of Manifest Destiny. Historian Frederick Jackson Turner in his "Frontier thesis" (1893) theorized that the frontier was a process that transformed Europeans into a new people, the Americans, whose values focused on equality, democracy, and optimism, as well as individualism, self-reliance, and even violence.
The Western United States, commonly referred to as the American West or simply the West, traditionally refers to the region comprising the westernmost states of the United States. Because the U.S. expanded westward after its founding, the meaning of the West has evolved over time. Prior to about 1800, the crest of the Appalachian Mountains was seen as the western frontier. Since then, the frontier moved further west and the Mississippi River was referenced as the easternmost possible boundary of the West.
The West mostly comprises arid to semi-arid plateaus and plains and forested mountains.
At the outbreak of the war, regular U.S. Army troops in the District of Oregon were withdrawn from posts in Oregon and Washington Territory and sent east. Volunteer cavalry and infantry were recruited in California and sent north to Oregon to replace the Federal troops and keep the peace and protect the populace. Oregon also raised the 1st Oregon Cavalry that was activated in 1862 and served until June 1865. During the Civil War, immigrants to the newfound gold fields in Idaho and Oregon continued to clash with the Paiute, Shoshone and Bannock tribes of Oregon, Idaho and Nevada until relations degenerated into the bloody 1864 - 1868 Snake War. The 1st Oregon Volunteer Infantry Regiment was formed in 1864 and its last company was mustered out of service in July 1867. Both units were used to guard travel routes and Indian reservations, escort immigrant wagon trains, and protect settlers from Indian raiders. Several infantry detachments also accompanied survey parties and built roads in central and southern Oregon.
Oregon's second United States Senator, Col. Edward Dickinson Baker was killed while leading Union troops at the Battle of Ball's Bluff near Leesburg, VA on October 21, 1861. His death in battle occurred exactly one month after another Oregonian, Captain James W. Lingenfelter of Company B,71st Pennsylvania infantry, was killed while on the picket line. In civilian life, Captain Lingenfelter had been a practicing attorney in Jacksonville, Oregon. He had been visiting in the East when the war started and enlisted to serve with Colonel Baker.
The Department of the Pacific or Pacific Department was a major command (Department) of the United States Army during the 19th century.

The United States of America (USA), commonly referred to as the United States (US), America, or simply the States, is a federal republic consisting of 50 states, 16 territories, and a federal district. The 48 contiguous states and the federal district of Washington, D.C., are in central North America between Canada and Mexico. The state of Alaska is the northwestern part of North America and the state of Hawaii is an archipelago in the mid-Pacific. The country also has five populated and nine unpopulated territories in the Pacific and the Caribbean. The largest of these territories are Puerto Rico and the American Virgin Islands which are an official part of the United States. At 3.79 million square miles (9.83 million km2) in total and with around 316 million people, the United States is the fourth-largest country by total area and third largest by population. It is one of the world's most ethnically diverse and multicultural nations, the product of large-scale immigration from many countries. The geography and climate of the United States is also extremely diverse, and it is home to a wide variety of wildlife.
Paleo-indians migrated from Asia to what is now the U.S. mainland around 15,000 years ago, with European colonization beginning in the 16th century. The United States emerged from 13 British colonies located along the Atlantic seaboard. Disputes between Great Britain and these colonies led to the American Revolution. On July 4, 1776, delegates from the 13 colonies unanimously issued the Declaration of Independence. The ensuing war ended in 1783 with the recognition of independence of the United States from the Kingdom of Great Britain, and was the first successful war of independence against a European colonial empire. The current Constitution was adopted on September 17, 1787. The first 10 amendments, collectively named the Bill of Rights, were ratified in 1791 and guarantee many fundamental civil rights and freedoms.
