BOMBER COMMAND
Daylight Ops:
  • 36 Venturas bomb the railway yards at Boulogne, shipping at Cherbourg and the power stations at Zeebrugge without a loss.
Evening Ops:
  • 339 aircraft are sent to attack Stettin. Included in the total are 194 Lancasters, 134 Halifaxes and 11 Stirlings.
  • This raid on a target more than 600 miles from England proves to be the most successful attack beyond the range of Oboe during the Battle of the Ruhr. Visibility is good and the Pathfinder marking is excellent. 24 fires are still burning when a photographic reconnaissance aircraft flies over Stettin almost 36 hours later.
    • 13 Lancasters, 7 Halifaxes and 1 Stirling are lost.
  • 86 Stirlings raid the Heinkel factory near Rostock but a smoke screen conceals the target and the bombs are scattered.
    • 8 Stirlings are lost.
Minor Ops:
  • 11 Mosquitos carry out a 'nuisance' raid on Berlin as a diversion for the forces attacking Stettin and Rostock. 18 Wellingtons lay mines off the Brittany ports and there are 3 OTU sorties.
