Book excerpt: This is a companion volume to Norman Friedman' s highly successful British Battleships 1906-1946 and completes his study of the Royal Navy's capital ships. Beginning with the earliest installation of steam machinery in ships of the line, British Battleships of the Victorian Era traces the technological revolution that saw the introduction of iron hulls, armor plate, shell-ring guns, and the eventual abandonment of sail as auxiliary propulsion. This hectic development finally settled down to a widely approved form of pre-dreadnought battleship, built in large numbers and culminating in the King Edward VII class. As with all his work, Friedman explains why, as well as how and when, advances were made, and locates British ship design firmly within the larger context of international rivalries, domestic politics, and economic constraints. The result is a sophisticated and enlightening overview of the Royal Navy's battle fleet in the latter half of the nineteenth century. British Battleships of the Victorian Era is well illustrated--a comprehensive gallery of photographs with in-depth captions is accompanied by specially commissioned plans of the important classes by A. D. Baker III, and a color section featuring the original Admiralty drafts, including a spectacular double gatefold.
