They left Vermont and headed west (or east in some cases) for a variety of reasons, not the subject of our study here, but native Vermonters served in regiments from other states during the Civil War. Select from the above menu for lists. There is one exception, the 1st New England Volunteer Cavalry.
Based on the 1860 census, of the 413,852 native-born Vermonters in the United States, 174,765 (42.2%) lived outside Vermont. (William S. Rossiter, "Vermont. An Historical and Statistical Study of the Progress of the State." Publications of the American Statistical Association, volume XII, Nos. 93, March, 1911. Boston: American Statistical Association, 1912).
Given that statistic, one would assume a good number of native Vermonters served in other State's units, and indeed they did!
More than 8,800 in just seven states alone! More than 2,600 in New York, almost 1,500 in Illinois, nearly 1,450 in New Hampshire, and 1,250 in Massachusetts. The numbers are still impressive in some of the mid-western states: 771 in Iowa, 649 in Minnesota, 586 in Wisconsin.
Since the focus of our detailed study is organized units from Vermont, we normally don't collect more than these soldiers' units and personal information, and attempt to locate their final resting places, which also supports the Sons of Union Veterans of the Civil War Cemetery Database Project.
NOTE: In some cases, having been in, and served from other states, they returned to Vermont and rest in the shadows of the Green Mountains with their brethren.
