Following the surrender of Vicksburg (1863), he guarded supply lines as Gen. William T. Sherman advanced towards Jackson, and later his division was responsible for construction of the defenses guarding the approaches to that city. McArthur and his division were in the forefront in the decisive battle of Nashville (1864).
