Military records are an excellent source of genealogical and historical information. The United States have been at least eleven major wars, numerous Indian wars and two conflicts since colonial times. There are two major categories of these records that the family researcher will want to research.
The first is the service record which usually contains enlistment records, orders, reports and commendations and muster rolls. The other records is the pension application files which usually contain affidavits made by the veteran and his neighbors, friends, relatives, etc. to prove his claim; the dates of his service; his date and place of birth; date and place of marriage his heirs and their birth dates and places; and possibly information from his family Bible.
For Colonial War information, the records include rosters, rolls and lists. Most of these records have been published and can be found in genealogical and historical libraries across the United States.
For Revolutionary information, the records include rosters, rolls, correspondence and field reports, dates of enlistment, state from which he served, sometimes his physical description and date and place of birth. Some of the original service records were destroyed by fire, but those remaining are on file at the National Archives and are indexed.
