The Battle of Albuquerque was a small engagement of the American Civil War in April, 1862. Between General Henry Hopkins Sibley's Army of New Mexico and a Union Army under Edward Canby. The Confederates were on the retreat from New Mexico Territory after the Battle of Glorieta Pass. On April 8, Sibley's force occupied Albuquerque for a second time as they made their way south back to Confederate Arizona. Edward Canby's army attacked and skirmished with the rebels at the town for a day at long range before retiring with minimal casualties on both sides. The rebels ended the occupation of Albuquerque a few days later.
