3 June 1940 - around 13h00:

5 minutes after the GC III/1 received a confusing alert message from the 21st Groupement, the ground vibrates and a terrible grumbling is heard, all the personnel of the squadron know what it means, the soldiers rush up to their anti-aircraft weapons while a part of the mechanics is running to the trenches hidden in the woods that border the airfield, the other part is running, along with the pilots, to the 24 Morane-Saulnier hidden in the same woods. And there appeares, coming at the tree top level, 12 Dornier bombers which fly throught all the lenght of the runway without dropping a bomb or firing a bullet, thought, as they pass, all those who aren't in the trenches jump to lie face down on the ground. Once they passed, all the men rose to look in the direction where the bombers went, wondering what they were doing.
As some pilots are rushing to prepare themselves to take off, the Squadron Leader gives the order to leave their aircrafts as all the pilots, excepted the alert patrol, have to be around when the order of take off will be given. If the airmen are obliged to stay on the ground, the airtillerymen are still nearby of their pieces. Everyone know that this formation wasn't the only one of the day and the time gave them reason; 10 minutes after the passage of the first 12 bombers, a new grumbling, muffled this time, envelop the airfield, as they rise their heads, they can see, up in the sky at around 2 000m, another formation of bombers. This time, no hesitations, a flare tears the sky and the judders of 4 Hispano-Suiza 12Y start. Once the engines are running at their normal pace with a normal temperature, they are launched at their full power by their pilots, dragging the aircrafts on the runway. Roland is one of them, he's in the fourth aircraft of the formation, and as he leaves the ground, one of the aircraft in front of him, its undercarriage still down, is surrounded by smoke trails and several sparks appears on the whole surface of the aircraft which, badly damaged, now emits a black smoke from its engine and a white trail flows on the side of its fuselage. In the mean time, the leader aircraft is also pursued by some projectiles but as they begin to reach it, the pilot breaks violently on the right to avoid to be shot like the other one. Their pass ended, the enemy aircrafts, two dozens of Messerschmitt 109 and 110, overtake the fighters which just took off. As one of the Bf-110 passed near of the fighters, Roland took his chance and rose the nose of his Morane, the safety of his guns already off, he fires of all his weapons when he judges he has enough deflection. The smoke trails first are a bit forward of the twin-engined but quickly come over it, making sparks on the left engine which delivers an explosion as a 20mm shell just reached it. In flames, the German pilot has no other choice than to crash land his aircraft in a field.

Meanwhile, on the airfield, one of the Polish Lieutenant has started the engine of his aircraft and tries to take off as the bombs fall around of him but his action is cut as one of the landing gear leg enters in a bomb hole and makes the aircraft pass on the nose, the canopy slides back and the pilot jumps out of the aircraft and runs to the wood to take another one with the one he succeeds his take off but its landing gear refuses to raise.
As the Moranes, outnumbered, are trying to dogfight the German aircrafts, they can see the bombers, up there, leaving the area without being bothered by them, though, a few of them let a light trail behind them as the AAA has succeeded to touch them. After a very little time, the German escort leaves the dogfight by climbing at full throttle, the Moranes, unable to follow them, have no other choices than to land back, avoiding the holes let by the bombs.

The first aircraft shot by the German managed to land on another airfield a bit further, his pilot is safe and sound, the second aircraft that have been shot was the one of the commander of the 5th Escadrille who managed to land correctly with very light damages his aircraft on its airfield. Though the runway was again damaged when the damages caused by another bombing 8 days earlier were not even repaired, no aircraft was destroyed and none was killed neither. As for the victory of the Adjudant-Chef Roland Bulard, the both German airmen walked away from their aircraft but were taken as prisoner later.

Here, at the end of the day, Roland went to the crash site of his prey in order to inspect it.
