Yesterday, I was introduced to a website documenting the 79th PA Vol Inf. The website is based on letters written by soldiers in the regiment.

Coincidentally, this part of Negley’s brigade left Pittsburgh on one of the six steamboats destined for Louisville. The steamboat, the str Clara Poe, commanded by Capt Thomas W Poe from Georgetown, PA, was one of those transports.
A fun site. Make the time to have a look.
