In addition, it was the duty of the Technical Section to keep the Chief of the Service fully informed on all the latest developments in gases and to get that information in shape so that the Chief with his increasingly wide range of duties would be enabled to keep track of them without reading the enormous amount ordinarily written. A much earlier start on technical work would have proved of immense advantage. In case of another war, the technical side of chemical warfare should be taken up with the very first expedition that proceeds to the hostile zone. Had that been done in France, we would have had masks and gases and proper shells and bombs at least six months before we did. INTELLIGENCE While Intelligence was for a long time under the Training or Technical Divisions, it finally assumed such importance that it was made a separate Division. It was so thoroughly organized that by the time of the Armistice the Chief of the Division could go anywhere among the United States forces down to companies and immediately locate the Gas Intelligence officer. =Intelligence Division.= This work was started by Lieutenant Colonel Goss within a month after he reported in October, 1917. The Intelligence Division developed the publication of numerous occasional pamphlets and also a weekly gas bulletin. So extensive was the work of this Division that three mimeograph machines were kept constantly going. The weekly bulletin received very flattering notice from the British Assistant Chief of Gas Service in the Field. He stated that it contained a great deal of information he was unable to get from any other source. Among other work undertaken by this Intelligence Division was the compilation of a History of the Chemical Warfare Service in France. This alone involved a lot of work. In order that this history might be truly representative, about three months before the Armistice both moving and still pictures were taken of actual battle conditions, as well as of numerous works along the Service of Supplies. Without going into further detail it is sufficient to say that when the Armistice was signed there were available some 200 still pictures, and some 8,000 feet of moving picture films. Steps were immediately taken to have this work continued along definite lines to give a complete and continuous history of the Chemical Warfare Service in France in all its phases. The intelligence work of the Gas Service, while parallel to a small extent with the General Intelligence Service of the A. E. F., had to spread to a far greater extent in order to get the technical details of research, manufacture, development, proving, and handling poisonous gases in the field. It included also obtaining information at the seats of Government of the Allies, as well as from the enemy and other foreign sources.
