Sorry for all the misspelled wording. I hope that it could be understood. I'm like Bryan H. the darn keyboard is to blame.

As the war progressed the lines I explained were taken up whenever possible and move to other areas. This was because of the shortage of usable wire in Arkansas. We do know that a wire was running between Arkadelphia-Old Washington into Texas. At one point in 1863 the line running to Red fork was ordered to be taken up and moved to run between Little Rock and Arkadelphia. As the Confederates abandoned Little Rock I am sure that many of the Telegraph lines were relocated.

As in the example of the "Flying Telegraph", skilled people could take down and put up wire almost on the run. As explained in a couple of the links that I sent you most of the wire was uninsulated bare wire. The telegraph line was a single wire construction and used the ground as a return line in order to complete the curcuit.

Trained telegraphers was also a problem. The code which was commonly used at the time called the "American code". It required a trained "ear" to properly hear and translate the clicks (dots) and pauses (dashes) of the messages recieved. To get around the lack of trained Telegraphers to use the "American Code", the signal corps of both sides more common used the same code and that used for signalling with signal flags. This was bases on a combination of 1, 2, or 3 "clicks". In this manner the operators only had to write down or send the series of clicks, and a signal officers could decipher the message. This would also mean that the operator himself may not even know what he was sending.

Yes it is an interesting study and it also seems to unlock some of our understanding of the conduct of the war in general as there were several battle which were impacked by the use of the Telegraph and the problems associated with it. The Battle of Chancellorsville is one such battle were the breakdown/failure of the Telegraph system of the Union Army greatly influenced the outcome of that battle.
