General History

Confederate States of America formally established its Confederate Signal Corps on 19 April 1862 making it the first independent branch of professional military signalmen in history. Signal messages were sent by means of flags, torches, or lights, by combinations of three separate motions. Where a letter was composed of several figures, the motions were made in rapid succession without any pause. Letters were separated by a very brief pause, and words or sentences were distinguished by one or more dip motions to the front.
