Halifax DT620 took off from RAF Tempsford at 17:50 hrs on ‘Operation Slate’ to a drop zone codenamed Wrona 614 in Poland to their resistance fighters.

Reported to have been shot down on their outbound trip by Oblt. Martin Drewes (1) of 7./NJG (shown left) with his BF. Uffz. Hrachowina at 21:42 hrs. Oblt. Drewes had just taken off from his base at Kastrup to intercept the aircraft when at a very low height of 200 metres he intercepted at shot down the Halifax over the Baltic Sea just a couple of hundred metres off the coast near Store Heddinge in Denmark.

Sgt. Thomas Mairs body was never recovered and is remembered at Runnymede - the bodies of the remainder of the crew were either picked up or washed ashore during the following days.
