The Official records of the United States and Confederate Navies are also available. The War of the Rebellion Journal contents covers the years 1880-1901. It includes scanned images of reports, correspondence, seizures of Southern property, etc. sent to the War Dept. during the Civil War. It includes both Union and Confederate accounts. It is in chronological order but there is no online index.
Many libraries have the index.
Find the volume and page number for your subject in the index at the library. This is a great site with lots of wonderful information on Vermont in general and with great links for the various counties. They also have some really interesting articles. I especially liked their article on the Prehistory of Vermont . A small but nice selection of Vermont Resource material.
