Formation

The 'Department of the Pacific' was a major command (Department) of the United States Army during the 19th century. It was first organized on October 31, 1853, at San Francisco, California, taking over from the previous Pacific Division. The department reported directly to the headquarters of the Army in Washington, D.C. It oversaw the military affairs in the country west of the Rocky Mountains, except for the Territory of Utah and the Territory of New Mexico.
On September 2, 1854, the headquarters was moved to Benicia Barracks, in Benicia, California. In January 1857, the headquarters again returned to San Francisco.
On January 14, 1858, the Territory of Utah was placed within the Department.

Disbandment

On September 13, 1858, the Department of the Pacific was disbanded, replaced by two new departments: the Department of California and the Department of Oregon. The Department of California included the territory west of the Rockies, the Umpqua and Rogue River districts in Oregon, Utah and New Mexico. The Department of Oregon included the Oregon and Washington Territories.

Reborn in the Civil War

During the American Civil War the army again reorganized, and on January 15, 1861, the Department of the Pacific was reconstituted by consolidating the Departments of California and Oregon. The first commander of the new Department of the Pacific was Colonel (Brevet Brigadier General) Albert Sidney Johnston who was later to become a prominent General in the Confederate Army.
From 1863 to 1865 the department had five districts: California (headquarters co-located with Department of the Pacific), Humboldt (with headquarters at Fort Humboldt), Oregon (headquarters at Fort Vancouver), Southern California (headquarters at Drum Barracks), and Utah (headquarters at Fort Douglas).

★ Albert Sidney Johnston, January 1861 - March 1861

★ Edwin Vose Sumner, March 1861 - October 1861

★ George Wright, October 1861 - July 1864

★ Irvin McDowell, July 1864 - July 1865

Reorganized out of existence

In July 1865, the Department of the Pacific was reorganized into the Military Division of the Pacific with two subordinate departments: the Department of California and the Department of the Columbia. The first commander of the new Division of the Pacific was Gen. Henry Wager Halleck.

Remade for the Philippine Expedition

On 30 May 1898, Gen. Wesley Merritt established in San Francisco the Headquarters, US Expeditionary Forces and Department of the Pacific for the campaign to support Adm. Dewey's forces in the Philippines during the Spanish American War.^[1]
At the end of March 1900 the complexities involved in dealing with the guerrillas and governing the islands led to the transformation of what had been the Department of the Pacific into the Division of the Philippines with four geographical departments, each of which was, in turn, divided into military districts. This step brought an end to the VIII Corps.^[2]
