For the United States Navy during the Civil War, littoral combat operations were in its infancy. The United States Marines were expected to be able to conduct land operations but doctrine for amphibious operations and littoral operations was not well developed. During the Civil War there were some riverine type operations and some landing of troops, but should we consider these true amphibious operations? There was limited naval support for amphibious operation. The Navy was not equipped to engage in littoral operations but probably performed them on a limited basis.
