In 1850, A. C. Gibbs moved to the
Oregon Territory. In 1864, responding to orders from the
United States Congress, Gibbs raised an infantry regiment despite opposition from Oregonians. His term ended on September 12, 1866. After his term as governor, Gibbs was an unsuccessful candidate for the
United States Senate in 1866 to replace
James W. Nesmith with
Henry W. Corbett as the selection of the
Oregon Legislature. Gibbs then served as the
United States District Attorney for the
United States District of Oregon and as a commissioner for the state to settle war claims from the wars against the
Native Americans. Gibbs, as Oregon District Attorney, was controversially removed from office by President
Ulysses S. Grant's Attorney General
George Henry Williams, former Senator from Oregon, while Gibbs was prosecuting election frauds in Oregon. He then returned to private practice in Portland at what is now
Miller Nash Graham & Dunn LLP. ==Death==
