Secret Agent Man

From the History of the United States Secret Service,:

I [Lafayette Baker] at once reported to General Scott giving him all the information desired respecting Manassas, Fredericksburg, and Richmond, the resources and plans of the rebel chiefs, and the blockade running of the Potomac. He read with a smile, the letters from the Confederate Government, when I expressed my design to use them in tracking northern traitors in their treasonable alliance with the South. Expressing his gratification, he recommended my name to Mr. Cameron for permanent service as a secret agent of the War Department.
