The Confederate forces are estimated from 600,000 to 1,000,000 men, and ever since the conclusion of the war there has been no little controversy as to the total number of troops involved. The losses in the Confederate army have never been officially reported, but the United States War Department, which has been assiduously engaged in the collection of all records of both armies, has many Confederate muster-rolls on which the casualties are recorded. The tabulation of these rolls shows that 52,954 Confederate soldiers were killed in action, 21,570 died of wounds, and 59,297 died of disease. This does not include the missing muster-rolls, so that to these figures a substantial percentage must be added. Differences in methods of reporting the strength of commands, the absence of adequate field-records and the destruction of those actually made are responsible for considerable lack of information as to the strength and losses of the Confederate army. Therefore, the matter is involved in considerable controversy and never will be settled satisfactorily; for there is no probability that further data on this subject will be forthcoming. The immensity and extent of our great Civil War are shown by the fact that there were fought 2,261 battles and engagements, which took place in the following named States: In New York, 1; Pennsylvania, 9; Maryland, 30; District of Columbia, 1; West Virginia, 80; Virginia, 519; North Carolina, 85; South Carolina, 60; Georgia, 108; Florida, 32; Alabama, 78; Mississippi, 186; Louisiana, 118; Texas, 14; Arkansas, 167; Tennessee, 298; Kentucky, 138; Ohio, 3; Indiana, 4; Illinois, 1; Missouri, 244; Minnesota, 6; California, 6; Kansas, 7; Oregon, 4; Nevada, 2; Washington Territory, 1; Utah, 1; New Mexico, 19; Nebraska, 2; Colorado, 4; Indian Territory, 17; Dakota, 11; Arizona, 4; and Idaho, 1. It soon became evident that the official record of the War of 1861-5 must be compiled for the purposes of Government administration, as well as in the interest of history, and this work was projected near the close of the first administration of President Lincoln. It has continued during the tenure of succeeding Presidents, under the direction of the Secretaries of War, from Edwin M. Stanton, under whom it began, to Secretary Elihu Root, under whose direction it was completed. As a successor to and complement of this Government publication, nothing could be more useful or interesting than the present publication. The text does not aim at a statistical record, but is an impartial narrative supplementing the pictures. Nothing gives so clear a conception of a person or an event as a picture. The more intelligent people of the country, North and South, desire the truth put on record, and all bitter feeling eliminated. This work, with its text and pictures, it is believed, will add greatly to that end.
