Introduction
California supplied at least four cavalry units and nine infantry units to the Union Army (see below). Though these units stayed in the west, many California men went east and joined the Union Army there. California also sent gold east, replaced regular army forces stationed in the western territories, plus kept Sothern California and the New Mexico Territory from the Confederacy.

The Wikipedia article, California in the American Civil War, has more information about California's activities during the war.
