Lincoln's Secret Spy: The Civil War Case That Changed the Future of Espionage

[Jane Singer]

Fascinating, Roger! Thank you for posting about this fascinating character! I wonder what there is about him in the NARA?

For anyone who is interested there are a number of items/letters from Lincoln to Zacharie as well as correspondence from Zacharie to the President.

Go to the Lincoln Papers in the LOC. Upon first glance it seems that Zacharie was indeed "working" for Lincoln in a limited capacity.

Would be interested to see when the letters came to light. If I read correctly they were donated in 1919 but that may not be right.

Yes, some accounts of Zarachie's work are inflated or confabulated but there appears to be some truth here.
Fascinating!!!!!!
