The first combat patrol by the 95th Squadron was made on 15 March, consisting of three unarmed Nieuport 28 planes and one French pilot in a SPAD took off from the airfield at 11:30. A second patrol was carried out in the afternoon to carry out a barrage of the Marne between Chalons and Eppernay. Continuous air rads by the Germans in the vicinity of Vetrus led to the digging of zigzag trenches on the Aerodrome and falling shrapnel was a hazard from the French anti-aircraft guns. Patrols continued to be carried out by the French, but none of the accompanying American planes were armed.
