The term Borzna Regiment does not appear in widely available, reliable encyclopedic sources as a distinct historical or contemporary military formation. Consequently, it is not recognized as an established concept in the historiography of Ukrainian, Russian, or broader military history.
Possible interpretation
- The name likely derives from Borzna, a town in the Chernihiv Oblast of northern Ukraine. In the Cossack Hetmanate (17th–18th centuries), military‑administrative units known as regiments (полк, polk) were commonly named after the principal town or city that served as their headquarters. It is plausible that a unit associated with Borzna may have existed as a sotnia (company) or as part of a larger regiment, but reliable documentation of a standalone “Borzna Regiment” has not been identified in standard historical references.
Conclusion
Given the absence of verifiable information, the term remains unsubstantiated in scholarly and encyclopedic literature. Further research in specialized archival sources would be required to determine whether a regiment bearing the name “Borzna” ever existed.
