This is ""The Story of Union Sea Power in the Civil War"", and the Yankee fleet, like its crew, was largely improvised. The attacks on Confederate ports early in the war, although they buoyed up spirits in the North, were not well-conceived or well-coordinated. The vaunted blockade consisted for a long time of intensified coastal action and the Rebel captains soon proved their genius in slipping serenely past the ""surrounding armada"". Little by little, however, a powerful navy, capably manned, thoroughly outfitted, bravely and on the whole skillfully led, came into being. Yankee technique in seizing enemy ports and making amphibious landings won the attention of the military world. The South countered with iron ships, torpedoes, submarines, but the war at sea was overwhelmingly lost. Such is the neglected history of Lincoln's fleet- recapitulated here in somewhat scrappy form although all the major facts are included for the record and for reference.
