How Americans Served: Drafts, Volunteers, and Major Wars in U.S. History
Understanding how Americans entered military service, whether through volunteering or through a draft is an important part of understanding our ancestors’ lives. Many genealogists discover draft cards, enlistment records, pension files, or military service records while researching their family history.
