Southward ho! (1939)

Roy and Gabby return to Gabby's Texas ranch, after fighting with the Confederate military during the American Civil War, to find that a blustery Union Colonel whom they have previously hassled is now their district commander. Unbeknownst to the Colonel, however, is that the soldiers he believes have been sent to assist him are actually Union Army rejects who have come to loot the civilian populace under the guise of reinstituting normalcy to the former Confederate district.
