The North Carolina in the Civil War Message Board

Jeff Davis Sacrifices Eastern NC?

In his book, "The Civil War Coastal North Carolina", (2001) author John S. Carbone quotes Jefferson Davis as saying "it is not expedient to send troops to coastal North Carolina". I believe this was in a letter to Governor Henry T. Clark in 1861, but I cannot find the source and the author does not cite the quote. Has anyone heard this before?
