Col. Frank Moorman, G.S., who during the World War was Chief of the Radio Intel­ ligence Section, General Staff, General Headquarters, American Expeditionary Forces. In dealing with the results obtained by the various services conducted by his section, he said: ,,' "TRANSLATION AND CLASSIFICATION oF ENEMY DocuMENTs "The full possibilities of this service were not appreciated until just before the signing l of the armistice and no adequate provision was made for handling it. "In October many captured documents relating to the Signal Service and the use of codes began coming to this office. Many of them were very useful but of a highly technical nature which the regular translators of G. 2-A could not handle. The Signal Corps was not provided with translators. Many of the documents were of particular interest to this section and this was the only section having men with both the technical knowledge and familiarity with the enemy language necessary to insure proper translation. "It is certain that provision should be made for handling this work in the event of war with any highly civilized nation. "There will be submitted later a report of the enemy's liaison service now being prepared by an officer of this section. I will be unable to see this report before its sub­ mission to you, but I have entire confidence in the officer charged with its preparation." The report mentioned in the foregoing extract was prepared in January-March 1919, by Capt. Phillip B. Whitehead, F.A., and is presented below without any changes, additions, or deletions. This report merits careful study by signal intelligence personnel. WILLIAM F. FRIEDMAN, Cryptanalyst, I Chief of Signal Intelligence Section, ) Office of the Chief Signal Officer. JUNE 22, 1934.

I I • l PREFACE The following notes on the Liaison Service and Liaison Intelligence Service of the German Army are compiled mainly from original documents, part of which were captured by our troops and part of which have been received in translation from the French and British. These docu­ ments ha.ve been studied in the light of experience gained a.s a code officer. It is not possible with the material at hand to give a full account of the German Liaison Service. The study of this subject wa.s not undertaken until near the close of the war and con­ sequently the materia.! collected is incomplete. The purpose of this study ha.s therefore been restricted to the pointing out of the main features of the German Signal Service and estimating its effectiveness. (VII) j J REF ID:A58123 NOTES ON THE LIAISON SERVICE AND THE LIAISON INTELLIGENCE SERVICE OF THE GERMAN ARMY DURING THE WORLD WAR PART I LIAISON SERVICE A. PEACE ORGANIZATION In peace the personnel of the Signal Service was drawn from the Telegraph Troops (Telegraphentruppen), and consisted of: Six Prussian telegraph battalions and seven fortress telephone companies. One Saxon telegraph battalion and one fortress telephone company. One Wurttemberg telegraph company and one fortress telephone detachment. Two Bavarian telegraph battalions. The officers were drawn mostly from the engineers and pioneers, some from the infantry and railway troops. The uniform of the telegraph troops was similar to that worn by the pioneers, but a shako was worn, and the shoulder straps bore a "T." In January 1917, the telegraph troops were separated from the colllmunication troops, to which they formerly belonged, and were organized as a separate corps under the Chief of the Field Telegraph Service (Chef der Feldtelegraphie), who also controlled the telegraph and telephone systems in Germany. (1) 69408-35--2 B. DEVELOPMENT DURING THE WAR It would not be possible with the material now available to give a full account of the develop­ ment of the German Signal Service during the war. At the outbreak of the war the telegraph and telephone (with ground circuit) were the chief means of rapid communication. Wireless, as a means of liaison in the field, was still in the experimental stage and was used only by the larger units. Ground telegraphy was unknown. The Liaison Intelligence Service was at best in a rudimentary stage, although the possibilities of wireless interception were undoubtedly forsetm and provided for at the outbreak of the war. In consequence of the rapid development of the Liaison Service along new lines, there were during the first 3 years of the war radical changes in organization and a great increase in the personnel employed. The two outstanding features in the development of the
