Drum Barracks Civil War Museum

The Drum Barracks Civil War Museum is housed in the last remaining wooden building of Drum Barracks, named after Adjutant General Richard Coultier Drum, of the Department of the Pacific. The facility served as the Union Army headquarters in the Southwest (Southern California and the Arizona Territory) from 1861 - 1871. Drum Barracks, which was first called Camp Drum, served as the main staging, training and supply base for military operations in the Southwest, and occupied approximately sixty acres of land with an additional thirty-seven acres near the harbor.
