The I Corps Observation Group was an Air Service, United States Army unit that fought on the Western Front during World War I as part of the Air Service, First United States Army. It was demobilized in France after the 1918 Armistice with Germany on 15 April 1919.
The mission of the group was primarily to keep the friendly command informed of the general situation within the enemy lines by means of visual and photographic reconnaissances. It was called upon to effect, whenever necessary, the adjustment of U.S. Army artillery fire. In addition, it was expected that the group would serve to complete the schooling of pilots and observers and render them more competent to undertake intensive operations elsewhere on a larger and more complete scale.
Organized in April 1918 as 1st Corps Observation Group. The assigned 1st Aero Squadron was the first American air unit to ever see action in France, being the same unit which served under General John J. Pershing as part of the Pancho Villa Expedition while chasing Pancho Villa into Mexico in 1916.
Assigned to the I Corps, United States Army Air Service, First United States Army. Commenced active operations over the front occupied by the 26th Division, United States Army, between Flirey and Apremont on that portion of the front known as the Toul sector.
The pilots of these squadrons, with one or two exceptions, had never before flown in combat. The group and squadron commanders were in every case men of long experience in training work but had never flown to an appreciable extent under war conditions.
