"Twenty-Five Centuries of Sea Warfare" includes 45 maps, 54 line-diagrams, and 16 pages of illustrations. From the hollowed-out tree trunk to the latest nuclear submarine, man has used the sea to carry on his unending strife with his fellow men. Deeds of great bravery have been followed by savage slaughter; new weapons have been devised to counter hostile inventive genius; the whole future of empires has been thrown into the struggle for sea supremacy; and always there has been the sea itself, ready, with its changing tides and storms, to destroy the works and hopes and triumphs of whole fleets.
