JWNathan and Larry,
The Order of the Heroes of America was a pro-union order located in North Carolina, southwestern Virginia, and eastern Tennessee, but was not discovered by Confederate authorities until 1864.
And Larry, I hate to tell you, not all people who were Northern sympathizers in the South were known as US Army.
Besides the Order of the Heroes of America, there was the Peace and Constitutional Society, organized in Arkansas, and the Peace Society, which existed in Alabama, East Tennessee, Georgia, Mississippi, and perhaps even Florida.
All of these organizations were made up by Southern men who remained loyal to the Union after secession.
From the book, Disloyalty in the Confederacy, by Georgia Lee Tatum.
