who wereosition to offer valuable

advice were absent from Headquarters during the period the paper was being prepared and thus unavailable to assist.

When this project was first discussed with the then Director of CIA, Mr. Allen Welsh Dulles, he ordered that, in the Interests of security, as little as possible concerning the project would be reduced to writing. It is probable that few orders have been so conscientiously obeyed, and yet there

reat many cubic feet of files connected with this These files mainly concern technical and administrative matters. Only those details which, in the opinion of the writer, are necessaryroad understanding of the manner in which the project's objectives were accomplished have been included ln this paper. Those Interested in additional data may wish to consult the files.

In addition to setting forth significant developments, the writer has attempted to provide Insight Into tbe reasons for certain courses of action. At times thispeculative approach. The judgments derived from suchwere shared by all those actively concerned in the management of the projoct, and it is the writer's hope that they are accurately expressed in the following paper. Any error ln this respect, however, is tho sole responsibility of tho writer.

The exact moment when the idea emerged ofunnel to Intercept Soviet and East German communications is somewhat obscure,' umber of factors must be considered, among them the following:

For this reason it was decided that the tunnel should be lined with steel. Ihe same sand content contributed greatly to the danger of cave-ins at the face of the tunnel, and to eliminate thishield was devised

with horizontal "blinds"

so arranged across its face that should even dry sand be encountered the danger of cave-ins was virtually eliminated. The tunnel liner was formed of sections of heavy steel plate so constructed that, when bolted together, five sectionsteel ring approximately six feet in diameter andnches long. Provision was made for bolting these rings together toontinuous tube of solid steel. The men worked under cover of the shield described above (which was slightly larger in diameter than the steel liner) and when sufficient material had been excavated, the shield was forced forward withjacksew section of liner was bolted in place. Since this methodoid of approximately one and one-half inches around the liner (remembering that the diameter of the shield was greater than that of thecrew-type removable plugs were built into every third section of tunnel liner. This permitted removal of the plugs and the forcing of grouting material under high pressure to fill the void

It is axiomatic that native fluency is usually available only in natives, and

Considerable thought was given to the quantity and content of the material available from the target and the manner ln which it was to be processed. It was in this field, perhaps, that we experienced some of our greatest problems. It had been decidod vory early in the project's planning stages to maintain the strictest possible security measures. inimum precaution security checks were mado on each individual who in any way became knowledgeable of the project's mission, and tho same standards in force forfor

The "thuds" the microphone picked up were caused by the pollco officer in charge stomping his feet on the road surface to keep war*.

The initial shipment across the East Zone to Berlin consisted of one and one-half freight trains, the loss of anyof which could have blown the project. For security purposes alltems, such as the tunnel liner, were double crated and banded and subjected to severe drop tests before they left the ZI. Similar items were differently packaged for deception purposes.

It should be noted that personnel andwere programmed initially to exploit approximately

percent of the anticipated take. In retrospect,this could be considered overly cautious. In Justification of this decision it should be said that no one had evereet under clandestinewith the expectation ofarget two inches in diameter andnchesain German/Soviet highway. There were those who manifested certainon the feasibility of so doing, and it is greatly to the credit of those senior officials, both civilian and military, that, in spite of these reservations, the project was permitted to proceed.

Such examination as could be safely undertaken under the steady observation of East German border guards and Soviet officials indicatedlay lens existed in this particular spot,perched water table" the magnitude of which was unknown. Available information indicated that the clay lens possibly sloped down in the direction of the target and it was decided to proceed with the tunnel even though the top cover was to be less than half what had been anticipated.

Careful visual observation was maintained and tunneling operations stopped each time the German guards walked over the tunnel on their regular patrols. Pumps were installed to take care of the excess water. Observation logs were maintained, and since the highway under observation was the main road from East Berlin to the Schoenfeld Airport,Order of Battle information was obtained. It was also possible to estimate quite accurately the relative importance of individuals visiting East Berlin by observing the security precautions taken by tbe East Germans and the Soviets.

Both sides of the tunnel were lined with sand in bags as the tunnel proceeded and the excess spoil was hauled back to the basement of the warehouse. To facilitateooden track was laid on the floor of the tunnel and aelectric fork lift was used totring of rubber-tired trailers back and forth in the tunnel.

Excess humidity is probably one of the greatest enemies of electronic equipment. To guard against this problem the section of the tunnel immediately adjacent to the tap chamber was insulated and sealed with marine-type plywood to form, inlosed room. (See figs.nd IB.) Vapor barriers were erected and, ineavy "anti-personnel" door of steel and concrete was constructed to seal off the tunnel someards from its terminal end.

The moisture ln the air caused by the breathing and perspiration of the technicians doing the tapping operation forced the suspension of the operation several times to permit the air conditioning equipment to dehuraidify the chamber. All the components io the electrical isolationwere individually selected and subjected to rigorous tests to insure maximum reliability, and the lead-away cables were constructed of tbe best available materials, sheathed in lead, and handled in accordance with tbe highest telephone company standards. The strictest possible visual watch was maintained with the tap crew. In short, in this, as in all aspects of the operation, every effort was made to guarantee success even though in many instances it meant delay Id achieving the objective.


The tunnel was discovered (see1fteronths andays ofemorandumon6 (reproduced in its entirety as

The conclusion reached was that the loss of this source was purely the result of unfortunate circumstances beyond ourof the fact that one of the cables was in very poor physical condition (this was known from the beginning)ong period of unusually heavy rainfall. It appeared that water entered the cable in sufficient quantity to make itthus necessitating digging up sections of the cable and causing discovery of the tap.

As previously noted, considerable thought was given during the entire life of the project on the result its discovery would bring. In retrospect lt is probably correct to say that, among those most actively concerned with the project'sonsensus developed that the Soviets would probably suppress knowledge of the tunnel's existence rather than admit to the world that Free World intelligence organs had the capability of successfully mounting anof this magnitude. In other words, lt was felt that for the Soviets to admit that. had been reading their high level communications circuits would cause the Soviets to lose face. Perhaps fortunately, fate intervened, andossible consequence the Soviet course of action was exactly contrary to expectation.

The Commandant of the Soviet Berlin Garrison, who would normally have controlled the handling of the situation when the tunnel was discovered, was absent from Berlin and the Acting Commandant. Colonel Ivan A. Kotsyuba, was in charge. There is some reason to believe that he (for whatever reason) was forced toersonal decisionourse of action without benefit of advice from Moscow. At any rate his reaction was unexpected in that he invited the entire Berlin

(Sources as Indicated)

The following is an analysis of the Bast German press reaction to the discovery of the wiretap tunnel at the sector border between West and East Berlin. During the period under4 tootal ofailies per day and four weeklies were available for scrutiny; however, only the dailies reported and commented on the incident.

Mostly concerned with reporting and commenting on the incident were the East Berlin papers which, in some instances, devoted full pages of their local sections to reports andon the tunnel in addition to their front-page or second-page accounts of developments. The* provincial press gavetreatment to the matter only in few Instances, generally refrained from large articles or commentaries, and often carried pictorial material with only brief explanations. The least coverage was noted in the provincial press of other

than SED (Sozialistische Einheitspartei Deutschlands -Communist Party Germany) affiliation; none of these papers published any commentary, or any cartoon of their own, on the subject up topril, in fact.

Describing the tunnel as inspected by the journalists after the Soviet press conference, the papers pointed out that the installation was well designed and constructed, that the installation was costly and equivalentodern teler phone exchange, and that thef Britishsed in the installation was of such quality as to guarantee long service.

The East Berlin papers, which were leading in the reports on the issue, treated the matterbitterly seriouswhich represents an "international scandal"breach of the norms of international law." The papers, in their commentaries, addressed the West Berlin Senat,an all-Berlin understanding and stressing the necessity for united action, and insinuated that Berlin is being kept divided merely for the purpose of providing the espionage centers in West Berlinase for launching provocations against the GDR. Other commentaries by central and provincial papers contained calls for vigilance and for defense Only one paper printed an editorial on the incident. In commenting on the incident the press did notine

between the different developments, such as the pressthe Soviet protest, the GDR Government protest,ut,ule, the commentaries dealt with the incidenthole. Later, when tho first reaction of the West Berlin press was available, the central press swooped down upon the West Berlin press for attempting to belittle the incident and to divert attention from the "seriousness of the matter."

The few caricatures published by the papers were designed to slander the Americans.

Day by Day Reaction
