James L. Hoare

[Steve]

According to a June 2, 1866 report of the Judge Advocate's Office to the House Judiciary Committee, their investigation determined Campbell was one of eight fictitious witnesses:

Sanford Conover
William Campbell
Joseph Snevel
Farnum B. Wright
John H. Patten
Sarah Douglass
John McGill
Mary Knapp

The report listed their true identities, with Campbell's true name as Joseph A. Hoare, a New York born gas-fixer. The report also says the deception came to light when Campbell (Hoare) confessed everything to Col. L. C. Turner on April 29, 1866.

Searching the internet, I've seen Hoare's middle initial as "L" in some books, so I don't know which is correct. Confusingly, the report continues to call Hoare "Campbell", even after identifying him.

Here is a link to the report:
