The following information was received from Rod Sawyer in an email dated July 7, 2014:

I found this about one of Hope's Civil War soldiers, Ephraim Gould. It may be of some interest.
The stone for Ephraim Gould in Hope is a cenotaph. Ephraim is actually buried at Annapolis, Maryland, where he died.
[FindAGrave 43741007]
Ephraim enlisted into the Maine 31 Infantry, Company G [age 38] in Feb 1864.
He became a POW July 30, 1864 and was exchanged in March 1865.
The story of Ephraim's passing in "Three Years in Field Hospitals of the Army of the Potomac" by "Mrs. H" [Anna Holstein] 1867
She is writing about POWs returned from Southern prisons. [edited for readability]

In another ward was a man who had endured longer imprisonment and greater suffering. His name is Ephraim Gould, from Maine.
His mind seemed entirely gone. He was only conscious of his prison life and that was all fearfully distinct.
Today there seemed a gleam of returning reason. Observing a lady near him, he called out for his wife and asked, was she here? had she written? or was it all a dream?
Fortunately his wife had been written to and a letter received from her. Some money was handed to him and told that it was his own. He looked at it intently for a moment and then remarked, "Surely that is United States. It don't look like the rebel stuff!" Then, recognizing a ten, a five, and so on, gave their value correctly.
He inquires as a little child would do, how he must get out of bed, must he ask if he wants to sit up, and so on.
It is the most complete awakening of an imbecile man that I have ever seen.
To the regret of all who knew him, this was but a faint glimmer of reason.
Once more he was conscious for a short time, then sank into the repose of death.
