Dear Susan Platt,
Thank you for posting your request on History Hub!
We were unable to find any records concerning the Vermont State Militia for the year 1838 in our catalog at the National Archives. We were able to find some resources online referencing the history of the Vermont State Militia during that particular year concerning the Lower Canadian Rebellions, but the National Archives does not contain any records for 1838. The National Archives does contain some files related to the Vermont State Militia during national conflicts throughout the 1700’s and 1800’s, should that help with your research.
As for other repositories who may have copies of the burned records, SNAC Cooperative is a good resource to look for additional records on the Vermont State Militia. It appears that there may be records at other repositories related to your search.
We hope this is helpful. Best of luck with your research!
Thanks so much - I will check out the resources.
