Civil War Ohio General Eli Long letters, cdv, reunion medal, and document tube

Description

I bought this lot a while back from a friend of Eli Long's decedents.
There are just over 40 page protectors of documents in the binder. When I received the documents they were just in an old box.
There are a couple letters and orders dated during the Civil War, but the vast majority are post war personal letters and vouchers for his pension. About 10 pages of the 40 are vouchers.
The parcel tube is empty but originally held the  documents for Eli Long's general commissioning documents. The story from the family was that they allowed the kids to take the tube and documents to school for show and tell and the documents never made it back home.
There are three cdv's and one is for sure Eli Long. The other two  haven't been identified as they aren't on the internet anywhere. The one picture with "general" written on it might be Eli Long as a general.
The Reunion medal is in great shape and doesn't seem to have ever left the box as it has the original makers tag on it.
I couldnt take a picture of every document, but I tried to get the more interesting ones.
Please ask any questions and I will do my best to answer them.
