|Lts. Alan Winslow and Douglas Campbell, 94th Aero Squadron
The first U.S. Air Service aerial victories by fighter planes in the American sector in France were by Lts. Alan Winslow and Douglas Campbell, two pilots of the 94th Aero Squadron, which had just been transferred to the front.
On Sunday morning, 14 April 1918, they were on alert at Gengoult Aerodrome near Toul, France. German planes were reported in the area and the two U.S. pilots, completely inexperienced in aerial combat, took off in their Nieuport 28s. Almost immediately they saw two German aircraft and attacked them directly over the flying field at less than 1,000 feet altitude, in full view of not only the Americans at Gengoult Aerodrome but also the French citizens of Toul. Winslow shot down an Albatross D.V and a minute later Campbell destroyed a Pfalz D.III. They were both back on the ground in a matter of minutes. This initial fighter combat by the U.S. Air Service, although probably successful due as much to luck as skill, convinced the French people that the Americans were "super-human."
On 31 May 1918, Campbell became the first U.S.-trained pilot to receive official credit for his fifth victory, thus becoming an ace. Winslow was decorated for a later action but was shot down on 31 July, lost an arm and spent the remainder of the war as a POW.
