The VII French Army was sent by ships to Zeeland this day and the Aéronautique Navale was ordered to cover it.
A Laté 298 of T3 flotilla was sent on reconnaissance on Escaut estuary under escort by 4 Potez 631 of AC1, from Calais-Marck. One of these four heavy fighters, flown by enseigne de vaisseau Philippe de Scitivaux, was late and was flying alone over the coast toward Ijmuiden when he met around 10h00 a Ju 52 of 3./KGzbV 9. According to some sources it was transporting ammunition for a fighter group (my comment: unlikely in this location) and exploded when hitting the sea, killing its crew.
The French pilot reported: "I saw a big three-engine German Arado aircraft . I attacked it five times and always from the rear. After each attack my gunner fired too when I disengaged. I stopped after the fifth attack, being wounded on the right arm, and I saw the German aircraft dive very fast, with two motors burning and the direction panels falling in small pieces. I came back to Marck at slow speed."

Usually in this book, the German victim is identified. In this case, Gillet only writes that the "Bulletin Air War 13939-1945 n° 237" effectifely signalled a Ju52/3m was lost in Ijmuiden. KGzbV 9 lost 39 Ju 52 during the day.
