Military History This Section looks at America at war, on the land and the sea and in the air. We offer not only the current field manuals but also documents that span our entire history starting with the citizen soldier of the pre-revolution through the War Between the States, to the major world wars and Viet Nam. Many of these documents are poorly circulated, firsthand accounts. Field manuals, some going back to the 1800’s, numbered War Department documents, campaign plans, and after action reports.
