Taking off from RAF North Killingholme to bomb the railway yards at Aulnoye in France. The bomber stream consisted of 132 Lancasters from 1 Group with a further 15 Pathfinder Mosquitoes.

Reports state that the attack was a success - inspections later confirmed that 287 bombs hit the target - some landed in fields close to the railway but the engine shed was hit with 30 locomotives taken out of action. - 340 homes were either destroyed or damaged with sadly, 14 civilians killed. 7 Lancasters were lost amounting to 39 aircrew lost their lives, 4 taken PoW and 6 others evading capture. One of the Lancaster crashed shortly after take off - all crew survived uninjured.

Lancaster LL836 is reported to have been shot down at 3000 mtrs. by German Nightfighter ace Hptm. Helmut Bergmann of 8./NJG4 1.5 km North-North-West of Achiet-le-Petit. (He claimed no less than 7 Lancasters on this night alone!) Abschuß Report: Opened fire from behind and below and fired at a range of 100 metres. The fuselage and starboard wing root burst into flames at once. Lancaster LL836 went down burning, hitting the ground at 02:43 hrs.

This was the 22nd victory for the Night fighter ace. He went on to claim a total of 34 kills before he was killed on the 6/7th August 1944 when he was shot down by Flt.Lt. John Surman in Mosquito MM449 from 604 Sqn. (Information from the Kracker Archives on this website)

Essay Lake, south of Takipy Lake was named after Plt.Off. William Essar in 1982.

(1) Flt.Lt. Picton and Fg.Off. Logan were awarded their DFC with effect 10th April 1944. Gazetted 18th December 1945.

(2) Sgt. Williams won an immediate DFM, gazetted on the 2nd May 1944. Citation reads:

"One night in March, 1944, this airman was the wireless operator (air) of an aircraft which attacked Berlin. Soon after the bombs had been released the aircraft was attacked by fighters and sustained much damage. After the enemy aircraft had been evaded it was discovered that the mid-upper and rear gunners had been wounded. Displaying great promptitude, Sergeant Williams extricated the rear gunner from his turret. He was unconscious and his oxygen mask was damaged. Without regard for his own welfare, Sergeant Williams removed his own mask and fitted it to the face of his injured comrade. He then attended to the needs of the other gunner to whom he rendered efficient first aid. But for his prompt aid it is doubtful whether his injured comrades would have survived the long flight home.. Throughout the sortie, Sergeant Williams displayed great co-operation and devotion to duty".

(3) Sgt. Waycott 1167439, was awarded his DFM whilst serving with 101 Sqn. Gazetted on the 13th July 1943.
