Promoted to Captain that same year, he went on to serve with distinction on both the frontier and in the Mexican War. In 1852, now Lieutenant Colonel Seawell was given command of the 8th Infantry Regiment serving in Texas. With the outbreak of the Civil War, he was promoted to Colonel and assigned command of the 6th Infantry Regiment until 1862. He spent the remainder of the war in non-combat duties.
