This short history of the operations of the First Gas Regiment covers only the high spots in its organization and work. It covers particularly its early troubles, as those are felt to be the ones most important to have in mind if ever it be necessary again to organize C. W. S. troops on an extensive scale. The Regiment engaged in nearly 200 separate actions with poisonous gases, smoke and high explosives, and took part in every big battle from the second battle of the Marne to the end of the War. They were the first American troops to train with the British, and were undoubtedly the first American troops to take actual part in fighting the enemy as they aided the British individually and as entire units in putting off gas attacks, in February and March, 1918. It would be a long history itself to recite the actions in which the First Gas Regiment took part and in which it won distinction.[16] [Footnote 16: Story of the First Gas Regiment, James T. Addison. Houghton Mifflin Co., 1919.] No better summary of the work of this Regiment can be written than that of Colonel Atkisson in the four concluding paragraphs of his official report written just after the Armistice: “The First Gas Regiment was made up largely of volunteers—volunteers for this special service. Little was known of its character when the first information was sent broadcast over the United States, bringing it to the attention of the men of our country. The keynote of this information was a desire for keen, red-blooded men who wanted to fight. They came into it in the spirit of a fighting unit, and were ready, not only to develop, but to make a new service. No effort was spared to make the organization as useful as the strength of the limited personnel allowed. “The first unit to arrive in France moved to the forward area within eight weeks of its arrival, and, from that time, with the exception of four weeks, was continuously in forward areas carrying on operations. The third and last unit moved forward within six weeks of its arrival in France, and was continuously engaged until the signing of the Armistice. “That the regiment entered the fight and carried the methods developed into execution where they would be of value, is witnessed by the fact that over thirty-five percent of the strength of the unit became casualties. “It is only fitting to record the spirit and true devotion which prompted the officers and men who came from civil life into this Regiment, mastered the details of this new service, and, through their untiring efforts and utter disregard of self, made possible any success which the Regiment may have had. It was truly in keeping with the high ideals which have prompted our entire Army and Country in this conflict. They made the motto of ‘Service,’ a real, living, inspiring thing.” SUPPLY
