These works were complemented by Eric J. Grove's definitive, annotated edition of Corbett's "Some Principles of Maritime Strategy" (Classics of Sea Power series, U.S. Naval Institute Press, 1988), which included Corbett's previously unpublished 'Green Pamphlet' on strategical terms. In addition, D. M. Schurman and John Hattendorf edited and wrote an introduction to Corbett's previously unpublished official study "Maritime Operations in the Russo-Japanese War, 1904–1905" (U.S. Naval Institute, 1994).
