THIS is undoubtedly the most valuable collection of historic photographs in America. It is believed to be the first time that the camera was used so extensively and practically on the battle-field. It is the first known collection of its size on the Western Continent and it is the only witness of the scenes enacted during the greatest crisis in the annals of the American nation. As a contribution to history it occupies a position that the higher art of painting, or scholarly research and literal description, can never usurp. It records a tragedy that neither the imagination of the painter nor the skill of the historian can so dramatically relate.
The existence of this collection is unknown by the public at large. Even while this book has been in preparation eminent photographers have pronounced it impossible, declaring that photography was not sufficiently advanced at that period to prove of such practical use in War. Distinguished veterans of the Civil War have informed me that they knew positively that there were no cameras in the wake of the army. This incredulity of men in a position to know the truth enhances the value of the collection inasmuch that its genuineness is officially proven by the testimony of those who saw the pictures taken, by the personal statement of the man who took them, and by the Government Records. For forty-two years the original negatives have been in storage, secreted from public view, except as an occasional proof is drawn for some special use. How these negatives came to be taken under most hazardous conditions in the storm and stress of a War that threatened to change the entire history of the world is itself an interesting historical incident. Moreover, it is one of the tragedies of genius.
