 It was these deficiencies that led Myer to his decision to use traditional Morse key technology and attempt to hire trained telegraphers, a decision that led Secretary Stanton to dismiss him as chief signal officer.All of the telegraph train assets of the Signal Corps were turned over to the Military Telegraph Service, but they did not use the Beardslee telegraph due to its unreliability.At their peak of usage in 1863, there were 30 telegraph trains in the field.
