PREFACE.

This compilation will be the first general publication of the military records of the war, and will embrace all official documents that can be obtained by the compiler, and that appear to be of any historical value.

The publication will present the records in the following order of arrangement:

The 1st Series will embrace the formal reports, both Union and Confederate, of the first seizures of United States property in the Southern States, and of all military operations in the field, with the correspondence, orders, and returns relating specially thereto, and, as proposed, is to be accompanied by an Atlas.

In this series the reports will be arranged according to the campaigns and several theaters of operations (in the chronological order of the events), and the Union reports of any event will, as a rule, be immediately followed by the Confederate accounts. The correspondence, &c., not embraced in the "reports" proper will follow (first Union and next Confederate) in chronological order.

The 2nd Series will contain the correspondence, orders, reports, and returns, Union and Confederate, relating to prisoners of war, and (so far as the military authorities were concerned) to State or political prisoners.

The 3rd Series will contain the correspondence, orders, reports, and returns of the Union authorities (embracing their correspondence with the Confederate officials) not relating specially to the subjects of the first and second series. It will set forth the annual and special reports of the Secretary of War, of the General-in-Chief, and of the chiefs of the several staff corps and departments; the calls for troops, and the correspondence between the national and the several State authorities.

The 4th Series will exhibit the correspondence, orders, reports, and returns of the Confederate authorities, similar to that indicated for the Union officials, as of the third series, but excluding the correspondence between the Union and Confederate authorities given in that series.
