Henry N. Derby was born in Wardsboro, VT on April 15th, 1846, later moved to Townshend where he enlisted for Federal service on December 8th, 1863 and mustered in on December 29th. He signed up for a three year enlistment with Company C of the 8th Vermont Infantry Regiment and traveled from Vermont to Louisiana, where he quickly became ill. He died on March 31st, 1864 presumably of disease; one of 241 from the regiment that died of such causes.
This photo just arrived in the mail from an eBay auction where the name of the soldier was not revealed. Luckily, I was able to tweak the lighting/contrast with photoshop to discover the name of the soldier before I bid. CSI: Civil War style!
Here’s a great link to a Vermont Historical Society collection from a Vermont soldier who also served with the 8th VT and also died in Louisiana.
