On 20 September, the 12th was transferred to Remicourt Aerodrome to prepare for the Meuse-Argonne offensive which began on 26 September.
During the Argonne operation the 12th Aero Squadron was very much in demand.
One morning after many assignments had been made, a call came in for a photographic mission.
Five planes were ordered for the flight, but only four observers were available.
Eddie Foy, a radio officer, volunteered to serve as an observer for the mission.
The planes encountered a large formation of Germans near the target and three were shot down, one carrying Eddie Foy, who had been wounded.
It is believed that he had the distinction of being the only non-flyer in the Air Service to be wounded and taken prisoner as a result of aerial combat.

In the last few months of the war, the 12th was called in many times to help locate Allied troops that had been cut off from their units.
On one such occasion during the Argonne offensive, the 82d Division reported that troops near Verpel, just east of Grand Pre were out of contact with division headquarters.
Because of the foul weather and approaching darkness, Captain Steve N. Noyes, squadron commander of the 12th would not send any of his pilots on the mission, going himself instead.
Flying in dense fog and rain, Captain Noyes located the troops and landed near the division HQ after dark.
The information proved to be exact, and the squadron was highly commended for this as well as many other missions.
The 12th completed its World War I operations from Julvecourt Aerodrome, where it moved on 5 November in order to operate closer to the front lines.
