The interception of the traffic is not only a complicated but also a very 

expensive enterprise, costly in numbers of personnel and equipment. I:f' there 

were time I'd show a few slides of typical intercept stations and intercept 

positions. You surel.y must realize that the business of intercepting a message 

while similar to is hardly identical with that o:f' receiving a message when the 

receiver is a legitimate member of the radio net. The intercept operator can 

hardly break in and say: "Hey, bud, I didn't get that 1ast group. Repeat it, 

please". The detection and copying or recG>l'ding the intercepted enemy traffic 

passed over modern high-speed communications systems is a very comp1icated but 

important step--and getting the intercept copy back to where it can be worked 

on, that is, getting it there in good time, is also complicated and highly 

important. Much of the traffic bas to be forwarded electrically to be of

the world; its communications center at Fort Ueade handles two million groups 

a day; it is the largest center in the world. It is fairly obvious that it's 

our communications peoples 1 job to get the tr.ll'fic to the desks o:f' the traffic 

C\ analysts and the crypta.nalysts as fast as pos~ible and as accurately as possible.

The next step after interception is traffic analysis, that is, the 

reconstruction o:f' the radio nets of the eneucy and the location o:f' their 

transmitter stations. This gives very important information on two counts. 

First of all, establishing or reconstructing the nets gives you order of

~ 

one that is not so obvious. It is that your COMINT successes will" be eliminated

and lest some of you jUllip to the conclusion that I've suddenly gone psychotic 

and am suffering from a delusion that I •m a reincarnation of the great Admiral. 

Maban, I hasten to explain that the "C" in such a titl.e for my talk is not the 

word "SEA" but the letter "C" and it stands for the word CRYPrOLCXUC. The 

~ ,.._ti tl.e 

of the talk would therefore be: "The Influence of CryptoJ.ogic Power on History."

to you without my calling them to your attention--and there will. be names of

~I said that a serious catastrophe was barely averted but even 

so the losses were quite severe, as can be seen from the following: 

"According to Eisenhower's personnel officer, American losses in 

the Battle of the Bulge totalled 75,898 men, of whom 8,687 were killed, 

47,139 wounded, and 21,144 missing. Over 8,SSS of these casualties were 

in the 1S6th Division. Because of heavy German attacks, 733 tanks and 

tank destroyers were lost. Two divisions, the 28th and 1S6th, were 

nearly completely annihilated, although the 28th Division did subsequently 

enter combat after being rebuilt. nl 

~Robert E. Merriam, Dark December, 1947, p. 211. 

What happened'l Why'l 

In an article which is entitled "Battlefield Intelligence: The Battle of -- ,.. .. :. - . . . , - • 

the Bulge as a Case History", and which was published in the February 1953 issue 

.. . . of Combat Forces Journal, B.allson Baldwin said: 

"Intelligence deficiencies and an astigmatic concentration upon our 

own plans with an al.most contemptuous indifference for the enemy's, set the

stage in December, 1944 for the German successes in the Battle of the 

Bulge--a case history in the 'dos and don 1 ts 1 of intelligence. 11

communications. 

The term was introduc~d to us by the Brl~ishwhen we began to play together in 

,• 

the cryptologic gardens; we found it useful and ~dapted it, too. Later on we 

came to use other secret words to designate this sort of intelligence and to c::f> 

"'1 

change the words from time to time, for security reasons. ~ COMINT -::: • 

is ccmposed Of three types or ~ategories Of intel.l.igence, and by far the greatest~~ part Of it comes from intercepting, recording, and studyillg enem;y radio traffic. Jj 

The three types or categories a.re: (1) Special intelligence, which comes from ~ '* ~~-..t~\o ~~~t.Y~~~.~-~" the solution and processing Of the encrypted messages themselves,\ (2) Traffic 

intelligence, which comes from the study of' what are called "the externals" of' 

those messages, data applicable to such things as their callsigns, the frequencies 

~~ ~,~~r ~~ u.,..,_-k~. employed, the direction or routings, and so o~f\and (3) Weather intelligence, '.) 

which comes from the study of' the enemy's weather messages,... which in wartime 

and even 'in peace time to a certain degree, are encrypted. In this audience 

it's hardly necessary to mention how important a role the weather plays in the

There is hardly need for me to give you a definition of COMINT, but 

perhaps I should cite its three principal objectives. First, to provide 

authentic in:f'orma.tion for policy makers, to apprise them of the realities of' 

the international situation, of' the war ma.king capabilities and vulnerabilities 

. of foreign countries, and of the intentions of those countries with respect to . 

war. Second, to eliminate the element of surprise from an act of aggression by 

-lf/J-
REF ID:A63391 

another country. Third, to provide unique information essential to the 

successful prosecution, and vital to a shortening of, the period of hostil.itieii.
