" Throughout this period , his thorough understanding of sea law and sea power , acquired during years of research in naval warfare ( when he was adding the ' Life of Mahan ' and other books to our naval literature ) enabled him to indicate precisely how control of the sea could be used to maintain and increase the economic life of a nation ; a zealous naval officer , he consistently pressed for the rigorous use of control of the sea by the United Nations to deny supplies and ammunition to the Axis Powers . " He not only contributed materially to a correct understanding of the law of blockade but his persistent presentation of the facts concerning the aid received by Axis Powers from the European neutrals was a large factor in suppressing this un - neutral traffic . His action reduced the economic resources available to the Axis , their ability to continue the war and definitely assisted in shortening the duration of the war . "
