REASON FOR LOSS:

A bomber force of some 78 aircraft were briefed to attack a wide range of targets both at the battle grounds in France and Belgium, the oil plant as well as communications and other industrial targets in Germany.

Taking off from RAF Driffield in Yorkshire at 20:00 to bomb the Synthetic Oil Factory in Buer. Understood to have been hit by flak and came down on farmland at around 23:30 hrs.

(1) On the 8th/9th September 1939, Plt Off. William Curwin Gavine Cogman was forced down by Belgian fighters (then a neutral country) in a 102 Squadron Whitley III K8985 DY:J. All his crew survived but then interned by the Belgian authorities. Only after intervention from the British Ambassador offering his apologies were the crew released.

After the incident as described on this page Plt Off. Cogman managed to evade capture and boarded the S.S. Abukir from Ostend also carrying large numbers of the British Expeditionary Force withdrawing from France and Belgium. The Luftwaffe bombed the ship for over an hour but failed to make any hits. At 01:15 hrs the Kriegsmarine E-boat, S-34 gave chase, although the ships captain managed to make a zig-zag course to try and ram the S-34. But the 8 knot top speed of the steam ship was no match S-34 fired two torpedoes - the first missed, the second hit the coaster amidships - sinking her within minutes, 24 survived out of the estimated 500 people on board.

(2) After being shot down Fg Off. Leonard Miller was found by a farmer in a field near the crash site. Fg Off. Miller had suffered a shrapnel wound to the leg so he was taken to a Doctor, Hendrik (Henk) Wiegersma, in the nearby village of Deurne. The wound was so serious that the Doctor decided to operate immediately. After the successful operation, Leonard recuperated for a few days at the home of Henk and his wife Petronella (Nel) (née Daniels) Wiegersma. In the meantime Henk had to determine how to return Leonard to Allied lines. In the interim and for the safety of all concerned it was arranged for Leonard to stay at a nearby Nuns convent. From there he travelled to Eindhoven and stayed with the De Vlam family, who were friends of Henk and Nel. From here they tried to move Leonard into France but unfortunately he was arrested by the Germans before he could be moved out of Eindhoven. The circumstance leading to his arrest have yet to be determined

As a PoW Leonard kept in contact with Henk and Nel, sending them letters and post cards about life in the camp. They in turn sent him food parcels and letters.

After his release, Leonard Miller transferred to the RNZAF and served with 74 Squadron. The then Flt Lt. Leonard Miller2451 was killed on the 2nd January 1946. Flying a Meteor F.III EE335 took off at about 10:55 hrs making a low level pass over the airfield at Warmwell an hour later, followed by a climbing roll into cloud at 2,000 ft. He emerged from that in a vertical dive and crashed into the ground close to Moreton Crossroads east of the airfield. He had 713 flying hours logged with 32 of these on the Meteor.
