Hello Robert,
From
the same source as above:
'On 15/05/1940 the 19 aircraft took off for Chartres. They had no maps and had to rely on a oral route description given by the French. which worked out well until they reached Dieppe, where they encountered heavy fog. The group, which was flying in a formation of three flights, broke apart.
One flight commander lost four planes and landed with the remaining three at Caen. the other aircraft landed on a meadow near Héricourt-sur-Samson.
A French officer gave them [the flight which landed in Caen? or the other aircraft?] information where to go and they took off again.
Shortly after take-off the S-IX of res-sgt vlieger C.J. van Hulzen and res-sgt leerling-vlieger C.Sitters crashed. Both were consumed by flames.
In the afternoon of 16/05/1940 the biplanes finally reached Caen. in the evening hours 17 Dutch training aircraft were counted. Two days later the car colonne from Souburg arrived, under command of kapitein Nieuwenhuis.'
