INSTRUCTIONS1. This code book, to be known as "Field Code No, 1", is

issued to division, brigade, regimental and battalion head-quarters of your division. Whether or not it is issued to

neighboring divisions must be determined by you before yousend them telegrams encoded by its use. (See G. O. No. 172,

G. H. Q. American E. F., 1918.)

2. IN CASE OF LOSS OF THIS BOOK, NOTIFY SUPERIORAUTHORITY AT ONCE. BURN IF IN DANGER OF CAPTURE.

3. Coded messages sent by telephone will be preceded by"FC1". If transmission is difficult, use the following telephone

alphabet, authorized by G. O. No. 103, 1918:

A—Able N—NanB—Boy O—OpalC—Cast P—PupD—Dock Q—QuackE—Easv R—RushF—Fox S—Sail

G—George T—TareH—Have U—UnitI—Item V—Vice

J—Jig \V—WatchK—King X—X-ray

• L—Love Y—YokeM—Mike Z—Zed

Example: If the operator receives "buy" as "vie,"

and difficulty is experienced in distinguishing "B" from"V," "buy" "may be spelled "boy-u-3r ."

4. Coded messages sent by telegraph or radio will be pre-

ceded by the group "FC1."

5. The use of this code for regular routine reports shouldbe limited to actual necessities. Such reports should be trans-

mitted by other means than radio or earth-telegraphy.

6. Avoid use of words not in code book when other word>with same significance are provided. Words spelled out, letter

by letter, not only take time to code, transmit and decode, but

they are one of the favorite points of attack by enemy codemen.

7. Where two or more code groups are assigned the sameletter, syllabic, word or phrase, first one and then anothershould be used so that in a series of messages each occurs abouttne same number of times. In particular, no group should everappear twice in the same message.

8. At least one group marketj "Null" should be used for

every ten code groups in a message. These should be placedat irregular intervals. A "Null" should always occur betweendouble letters; thus, the word "boot" would be encoded:

(bi (o) (Null) (o) (t)

AWK CUF NAW PCU JAK

Note that different groups are used for letter "0."

9. In messages sent by radio or earth-telegraphy, addresseswill be used only when context of message does not indicate

for whom intended. When used, they must be in code.

10. Signatures must be in code if message is sent by radio

or earth-telegraphy. Usually it will be sufficient to indicate

origin by some word in code book previously agreed upon byeach commander and his immediate subordinates.

11. The message handed Signal Corps operator should bi-

in the following form on any suitable paper:

"No. 1. 15:40 FC1 AWK CUF NAW PCU JAK

Send this message to First Division.

J. M.Capt., 1st Infantry."

12. Items should always appear in the following order:

(a) Number of message.(b) Hour of signature.

(c) Group designating code used.

(d) Body of message.('e) Order directing transmission.

Order directing transmission may also indicate meansto be employed when deemed necessary by thecommanding officer, but this will, in general, beleft to the discretion of the Signal Corps.

13. Blank spaces at end of book are for use of divisions for

designation of organizations and local geographical points, or

for such other use as may be desired.

Words assigned will be reported to Corps, Army and GeneralHeadquarters, and to neighboring divisions

14. Bead G. O. No. 103, G. H. Q. American E. F., 1918, beforeusing this code.

15. For the convenience of officers having occasion to use it

the "Emergency Code List," which has been issued to companies,is published in the front of this book.
