Brassey's Encyclopedia of Military History and Biography, edited by Franklin D. Margiotta, is a comprehensive single-volume reference work spanning nearly 1,200 pages. Originally published in 1994, the entries were specially selected from the six-volume International Military and Defence Encyclopedia (IMADE) to provide an alphabetised guide to warfare and military leaders throughout history. The text features a foreword by renowned military historian John Keegan and includes contributions from a wide range of international experts, including high-ranking officers and academics. Beyond biographical sketches, the encyclopedia covers technical and theoretical subjects such as combat operations, logistics, military law, and technology, making it a versatile resource for both general readers and specialised researchers.
