The card index you're referring to appears to be a comprehensive U.S. military service records database for volunteer soldiers who served between 1784 and 1811. This database includes the service records of approximately 21,000 individuals from twenty-two states and territories. The information provided in this database for each soldier typically includes:
- The soldier's full name.
- The rank held by the soldier within their unit.
- The company, regiment, and battalion affiliations of the soldier.
- The state or territory from which the soldier rendered their service.
This collection is invaluable for historical research, genealogy, and understanding the military involvement of early American citizens during this time. Accessing these records can provide insights into the military organization, individual contributions to early American military efforts, and the geographic distribution of those who served.
