According to a rough translation into English of an original Dutch website (see link #5 for the oiriginakl Dutch text):

"Fairey Swordfish crashed in polder South Blankenburg

In the night of 1 to 2 July, 18 Fairey Swordfishes and five Fairey Albacores aircraft attacked a concentration of ships in the Meuse east of Rotterdam. This operation was related to the German invasion plans against England, in which the occupying forces seized seized barges as landing vessels. The attack was carried out by three Fleet Air Arm Squadrons of the Royal Navy. It consisted of 12 Swordfishes of 825 Squadron, six Swordfishes of 812 Squadron and five Albacores of 826 Squadron. The weather conditions were not too good.

The clouds gave the pilots a lot of problems. It also made navigation difficult so that not all Swordfishes reached the target. Of the 825 Squadron aircraft, five Swordfishes did not return on their own base, but landed in various places in England.

Two Swordfishes of this Squadron were hit by anti-aircraft guns above the Netherlands. One of these aircraft crashed on the island of Rozenburg. The biplane L7646 quickly lost altitude and flew in the direction of the Kerkdijk. The crew members try to save their lives by using their parachute. However, it was too late for two of them, the amount was insufficient. Both died in the polder Langeplaat. The unmanned Swordfish hit one of the walls on the Kerkdijk for floodplains between the farm of Reijer and Leun van Galen and the Fort. The Fort was a dyke house in which several families lived, including the Leen Sonneveld and IJsbrand Koornneef familes

After the blow against the wall of the flood defense on the Kerkdijk, the Bristol Pegasus engine of the aircraft swung behind the Fort. Telephone and electricity wires were destroyed by the Swordfish. One hundred meters further L7646 crashed on the land of Adam Barendregt in the polder South Blankenburg burned out completely.
