Codes and Ciphers
a) Kaliber 21,5 cm = KALIBER ZWO EINS Y FUNF CM.
(Caliber 21.5 centimeters).
(Note that German uses a comma where we use a decimal point.
Furthermore, German uses a period -- in numbers -- where
we use a comma: thus 8.000.000 = eight million; 20,5 =
20.5. - Translator).
In any series of numbers, care is to be taken that commas are
also inserted when they have been omitted in the message text.
Example: An M 2, 23, 1 21 15.
Commas must be put in here -- one after 1, and one
after 21. Otherwise there will be possible confusions of the
last three numbers with 12, 11, and 5, or 121 and 15, or 12
26. When there is an immediate succession of numbers (of any number
of digits) between which no comma is permissible, they are separated
by YY. For exampie:
281 2 fdl. Kreuzer = QU ZWO ACHT EINS YY ZWO FDL. KREUZER.
27. Ordinal numbers are to be expressed either by X after the number
or by appending the syllable "TE" or "STE" to the number. For example:
1. April = EINS X APRIL

28. J-----J = Stress Mark QU = Square.
X = Period GRQU = Large Square.
Y = Comma FBKT = Fixed Point.
UD = Question Mark SM = Nautical Miles, Knots.
XX = Colon (Hyphen.
KK------KK = Parenthesis YY = (Dash.
29. In Fleet and Acknowledgment Procedures urgency signs are to
be put in before the address and signature and are to be enciphered
along with them.
30. In order to avoid having the text of "SSD-messages" always
begin with these letters, one of the following three code words can
be used instead of "SSD":
BIENE, WESPE, MUECKE.
After being deciphered, these words are to be supplanted by
