THE CHEMICAL WARFARE SERVICE 



The following letter has been sent by Gen- 

 eral Pershing to the chief -of the Chemical 

 Warfare Service: 



American Expeditionary Forces 

 Office of the Commander-in-Chief 

 March 2, 1919 

 Colonel Edward N. Johnston, 



Chief of Chemical Warfare Service, 

 American E. F., Tours. 



My dear Colonel Johnston: Now that active 

 operations have ceased and many of the personnel 

 of the Chemical Welfare Service are returning to 

 the United States, I desire to express to you and 

 through you to all of your officers and enlisted men 

 my appreciation of the valuable assistance they 

 have rendered to the American Expeditionary 

 Forces. 



Upon our entry into the war we were faced with 

 the problem of a new service in the organization 

 of which the experience of our Allies was so new 

 and so limited that there were few precedents to 

 follow. The best brains and experience among 

 students and teachers of chemistry were called into 

 service, and by rapid establishment of gas schools 



and the aid of specially trained personnel, all com- 

 bat troops were instructed in the necessary defen- 

 sive measures against poisonous gas. The first 

 gas regiment was trained and equipped, and rend- 

 ered good service in the two American offensives 

 of St. Mihiel and the Meuse-Argonne. 



Due to the energetic cooperation of all ranks, 

 much was accomplished in a very short time, for 

 which it gives me great pleasure to extend to you 

 all the thanks of your comrades of the American 

 Expeditionary Forces. Will you convey this espe- 

 cially to Brigadier General Fries, whose enthusiasm 

 and energy were such great factors in the success- 

 ful organization and development of the service. 

 Sincerely yours, 



John J. Pekshinq
