I seek to understand the equipment used to send and receive telegrams in the 1860s. A map of the various stations, at least in and around DC, would be ideal, as well as what apparatuses were used to repeat or amplify the signal between stations. An electrical signal sent over wires will attenuate to zero after only a few miles. Appropriate book citations appreciated.

I believe a brit named Wheatstone worked on the attenuation problem, and went a long way to solving it. I'm not writing your essay for you, however, and the initial citations will be found in the wikipedia article on this point.
On a related issue, did the north ever layout telegraph lines on a battlefield, and use them during combat? It strikes me that someone must have tried that. I believe the observation balloons had telegraph lines to the ground?

DinadansFriend:
I'm pretty sure I recently (maybe within the last year or two) read an account of battlefield telegraphy. But I do not remember where I read it. I think it was written by one of the men who ran the operation, so it may have been in a collection like Battles and Leaders (but I don't think it was actually B&L).
I'm pretty sure it was about the Overland campaign, and talked about how each (Corps?, Division?) HQ had a wagon with a reel of telegraph wire.
Maybe if I think about it more details will come to me, or maybe this will jog some one else's memory.

Telegraphy was frequently used in Civil War battles to communicate between command posts, and between the armies and Washington. It is mentioned in many battle narratives. Jack Coggins discusses its use briefly in Arms and Equipment of the Civil War, p. 108. He does not go into actual equipment other than wire. He notes that "during the last year of the war over one and three-quarter million messages were transmitted over the Federal System."
There is a 1910 book called Telegraphing in Battle : Reminiscences of the Civil War by John Emmet O'Brien. It is available in several reprint editions. I have not read this book and do not know whether the emphasis is on flag semaphore, electrical telegraphy, or ideally both.
