What military codes were used in the early 1800's
It can be late 1800's but mid may be better. British is okay but it is more than likely American. It is not Morse code. It is a code of letters and numbers. No this is not a homework question, if it were it would be much easier. Just a list of names of codes would be much help, I can research each myself. Cryptic I know, but its all I've got.
