The French Revolutionary and Napoleonic Wars encompassed a period when rival European fleets vied for naval supremacy, and naval tactics were evolving. The British Royal Navy emerged triumphant as the leading world sea power, and the epitome of Britannic naval strength was the Ship-of-the-Line. These 'wooden walls' were more than merely floating gun batteries: they contained a crew of up to 800 men, and often had to remain at sea for extended periods. This book offers detailed coverage of the complex vessels that were the largest man-made structures produced in the pre-Industrial era.
