"Immediatly after the crossing, the Mustangs of the Savoie group were engaged in so-called "army corps reconnaissance missions", which, because of the very low overcast and necessity to fly very low, turned out to be very dangerous. On one such mission, on April 17, Lt. Sainflou and Lt. Delgue were jumped by a dozen Bf 109s. Lt. Sainflou narrowly escaped by diving at full military power towards the ground, but Lt. Delègue was never seen again. Luckily, Lt. Labadie returned to the group on April 23, having escaped from a prisoner convoy."
There you go seems to be enough. Also they suffered damage from flak several times. Seems like combat.
+1 for french mustangs
