The Confederate Signal Corps was the military branch responsible for communications and information-gathering for the Confederate Army. They used methods like aerial telegraphy with flags and sometimes employed espionage, even running a secret network between Richmond and the North. Like the Union Signal Corps, they also provided valuable battlefield intelligence and artillery fire direction from elevated observation points.
