I gladly availed myself of the labors of others with pen and pencil, who kindly permitted me to make use of unpublished materials — such as drawings, photographs, diaries, and letters; and I am specially indebted to the courtesy of the proprietors of Harper's Weekly and Frank Leslie's Illustrated Newspaper, whose artists accompanied the great armies throughout the whole struggle, and preserved the lineaments of a thousand objects which were soon swept away by the storms of war. I was accorded free access to all official reports allowed to be made public; and chiefly from these and the drawings of engineers, the narratives of marches, battles, and sieges were compiled, with accompanying maps and plans. In the work will be found the portraits of the prominent actors, civil and military, of both parties to the conflict; also views and plans of battle-grounds; Headquarters of officers; weapons and ships of war; forts; arsenals; medals of honor, and other gifts of gratitude; costumes of soldiers; flags; banners; badges; and a great variety of other objects whereby the eye may be instructed concerning the materials used in the conflict.
The engravings, whilst they embellish the book, have been introduced for the higher purposes of instruction, and are confined to the service of illustrating facts. They have been prepared under my direct supervision; and great pains have been taken to make them correct delineations of the objects sought to be represented. In each volume will be found a table of contents, and a list of illustrations; and, at the close of the work, a copious analytical index. There will also be found biographical sketches of the prominent actors in the war, civil and military, arranged in cyclopedia form, and making an important Biographical Dictionary.
I am profoundly grateful to my personal friends, and to my
