The operators possessed of the ciphers, as well as the ciphers used, were practically independent of the commanders whom they were serving immediately under, and had to report to the War Department through General Stager all the dispatches which they received or forwarded.
I was obliged to leave the telegraphic operator back at Nashville, because that was the point at which all dispatches to me would come, to be forwarded from there.

As I have said, it was necessary for me also to have an operator during this inspection who had possession of this cipher to enable me to telegraph to my division and to the War Department without my dispatches being read by all the operators along the line of wires over which they were transmitted.

Accordingly I ordered the cipher operator to turn over the key to Captain Cyrus B.
Comstock, of the Corps of Engineers, whom I had selected as a wise and discreet man who certainly could be trusted with the cipher if the operator at my headquarters could.
The operator refused point blank to turn over the key to Captain Comstock as directed by me, stating that his orders from the War Department were not to give it to anybody--the commanding general or any one else.

I told him I would see whether he would or not.

He said that if he did he would be punished.
