The article reviews *The Windfall Battleships: Agincourt, Canada, Erin, Eagle and the Balkan & Latin-American Arms Races* by Aidan Dodson, which focuses on four dreadnought battleships originally built for foreign navies but acquired by the British Royal Navy at the outbreak of World War I. The book explores Britain's shipbuilding industry and its export warship trade, as well as naval arms races in the Balkans and South America involving countries like Argentina, Brazil, and Chile. It provides detailed wartime histories of the battleships Agincourt, Erin, and Canada, the conversion of the Chilean battleship Amiralte Cochrane into the aircraft carrier HMS Eagle, and the postwar fates of these and other vessels affected by the Washington Treaty. The work is noted for its thorough research, myth-busting insights, extensive archival photographs, and technical illustrations, making it a significant resource for those studying dreadnought-era naval history and World War I maritime affairs.
