Military unit
The Organization of the Air Service of the American Expeditionary Force on 11 November 1918, represents its maximum strength in World War I. Units of the Air Service are listed as assigned to the order of battle for that date, which was that of the Armistice with Germany. The first air unit arrived in France in September 1917, while the final air unit reaching the front did so on 9 November 1918. Unit operations began in April 1918. At the armistice, 57,508 officers and men served in the Air Service of the AEF, 24,512 in the Zone of Advance (combat area), and 32,996 in the Services of Supply (rear areas). Of its 6,861 officers, 4,088 were on flying status and 219 were qualified observation balloon aviators. 1,724 of those on flying status and approximately 100 of the balloonists served in combat units.[1]
The first two air combat groups formed in the AEF were the 1st Corps Observation Group, in April 1918, and the 1st Pursuit Group at Toul. Ultimately fourteen airplane and seven balloon groups were formed to support the operations of two field armies and five corps. The five pursuit and two bombardment groups were organized into two wings. The seven observation and seven balloon groups had one of each assigned to an army or corps air service. Two flexible "observation wings" were created to coordinate the reconnaissance activities of the five corps air services.
The basic units of the air service were the squadron for powered aircraft and the company for balloons. 45 squadrons (38 of which conducted combat operations) of aircraft and 17 companies of balloons served at the front. The 20 pursuit and seven bombardment squadrons were authorized 25 aircraft (including spares) and 18 crews each by the Field Service Regulations, while the 18 observation squadrons were each authorized 24 planes and 18 crews. Balloon companies were equipped with one balloon and approximately six observers each.
Air Service of the American Expeditionary Force (AEF)
The First Army Air Service was the largest and most diverse Air Service combat organization of the American Expeditionary Forces in France, and most American Air Service combat units were assigned to it when assigned to the front. The First Army Air Service dates to the first American Air Service personnel arriving in France. On 15 January 1918, Colonel William Mitchell was appointed Chief of the Air Service, I Corps, First Army. At this time, the I Corps was being formed for the purpose of administratively handling all of the American troops then on the Western Front. Headquarters was located at Neufchâteau, France. When the first American Aero Squadrons arrived at the front in April 1918, they were assigned to the quiet Toul Sector. At this time, the American Air Service on the front consisted of only a few Aero Squadrons of the 1st Pursuit Group.[3]
Created on 10 August at La Ferté-sous-Jouarre, the unit was formally organized on next 26 August at Ligny-en-Barrois, France. It consisted of the French Aerial Division, which consisted of a large number of pursuit and day bombardment squadrons. In addition, there was one other French pursuit group and three American pursuit groups-one American day-bombardment group-the 1st Army observation, and one French Army artillery group for the adjustment of long-range artillery fire. Eight night-bombardment squadrons of the British Royal Air Force. were to cooperate with the First Army Air Service whenever the tactical situation made such action expedient. The establishment of the First Army Air Service marked the first concentration of American air forces under its own commander.[4]
On 11 November 1918, all offensive flying ended at 11:00 am in compliance with the Armistice with Germany. As part of the Armistice, Allied Forces were to occupy the Rhineland area of Germany beginning on 1 December. The Third Army Air Service was established to be the air component of the United States Third Army. Units from the First Army AS contributed to over half the strength of Third Army AS, consisting of eight Aero Squadrons, and the headquarters of the III Corps Observation Group, and the VII Corps Observation Group.[5]
Headquarters was officially demobilized on 15 April 1919, its men arriving in the United States by the end of May and either transferred to Air Service units or returned to civilian life.[6]

The Second Army Air Service was established on 14 October 1918 by General Order, 287, GHQ. Paragraph 170 appointed Colonel Frank P. Lahm as Chief of Air Service, Second Army, thus establishing a separate Air Service organization. Headquarters was established at Croix-de-Metz Aerodrome, Toul, France.[3]
As a result of the Armistice with Germany, American occupation forces would be sent to the German Rhineland. The Third Army Air Service, under the command of Brigadier General William Mitchell was organized on 14 November as the Air Service component of Third Army. First and Second Army Air Services were ordered to transfer some of their units at the front to Third Army as part of its organization, along with personnel from their Headquarters staffs along with the required equipment, ranging from office furniture to airplanes. The 5th Pursuit Group was transferred to Third Army on 19 November, along with the 41st, 138th and 638th Aero Squadrons.[12]
On 15 April 1919, orders were received from Paris that the Second Army Air Service was to demobilize. The 85th, 141st, 168th, 258th, 278th, and 354th Aero Squadrons were transferred to Third Army, with the remainder of its organizations to report to the Services of Supply 1st Air Depot to turn in their equipment. After being processed at Colombey, personnel were assigned to the commanding general, Services of Supply, and sent to one of several staging depots in France where they awaited transport back to the United States and subsequent return to civilian life.[12]

Promptly after the armistice, the AEF formed the Third United States Army to march immediately into Germany while the remainder of the army demobilized. Brig. Gen. Mitchell was appointed to command the Third Army Air Service, on 14 November 1918.[13] Gen. Mitchell was replaced in January as commander of the Third Army Air Service by Col. Harold Fowler, a combat veteran of the Royal Flying Corps and former commander of the American 17th Pursuit Squadron.
The most veteran units of the Air Service were selected to form the new Air Service. A pursuit unit, the 94th Aero Squadron; a day bombardment squadron, the 166th; and four observation squadrons (1st, 12th, 88th, and 9th Night) were initially assigned.[14]

On 15 April 1919, the First and Second Army Air Services in France closed down, and the remainder of their personnel were returned to the United States. As a result, the Third Army Air Service was augmented with some of the few squadrons remaining in France. The Third Army Air Service's pursuit squadrons were consolidated at Coblenz. The 1st Aero Squadron and the remaining observation squadrons were consolidated at Weissenthurm and formed the III Corps Observation Group. The IV Corps Observation Group consisted of only the 85th Aero Squadron at Sinzing. The VII Corps Observation Group was at Trier.[15][16]
On 15 May 1919, the Air Service was ordered to demobilize all of its flying units, which reported to the 1st Air Depot, Colombey-les-Belles Aerodrome, France for subsequent transfer to the Services of Supply for processing back to the United States from Channel ports of Embarkation in France. The remaining Air Service units were consolidated at Coblenz, with the other facilities in the Rhineland closed and dismantled. All foreign aircraft were returned to the French and British governments and personnel were demobilized in the United States by the end of July 1919.[15]

The Treaty of Versailles officially came into effect in June 1919, and the Third Army Air Service was withdrawn.[17] The Third Army Air Service officially was demobilized on 2 July 1919,[15] and the American Forces Germany (AFG) took over the occupation duties in the Rhineland.[17] In July 1920, it was decided to add an Air Service organization to the forces of the AFG, and on 23 July a detachment of officers and men were deployed to Germany, under the command of Major Frank M. Andrews.[18] They were not assigned to any specific Aero Squadron, but to the AFG directly.
The Air Service personnel were established at Weissenthurm, south of Coblenz on the Rhine River. A new aerodrome was established, and some Bessonneau hangars were erected and quarters were established for personnel and offices. The contingent was equipped with 24 De Havilland DH.4 aircraft, powered by American Liberty engines.[19] In March 1921, Army Engineers had erected facilities on the airfield and the Americans were moved to the airfield from the temporary facilities they occupied in the town during the winter. Occupation duties included all sorts and types of flying, such as test flights, photos of radio telegraph and radio telephone missions, joint flights with infantry, cavalry and artillery units during the winter and spring maneuvers, cross country flights and passenger carrying. A significant amount of aerial photography was taken for cartographic missions, and large mosaics of photos were created.[18]
The postwar occupation mission was not popular with the American people, nor with the Americans sent to Germany, nor with the Germans. In 1922, President Harding began withdrawing American forces from the Rhineland. All AFG aviation activities were shut down in April and all of the excess equipment was disposed of through sales.[19] On 24 January 1923, the last American forces departed from Germany, leaving Coblenz to the French, formally ending the United States involvement in World War I.[17]
