"
The attack on Biggin Hill was severe and all but put the airfield out of action. It also saw the deaths of two female ground personnel – ACW1 Edna Button and NAAFI lady Mary Cremin. 39 year old Edna came from Tasmania and is buried in Cray, Kent, whilst 24 year-old Mary came from Cork, Ireland, and is buried in Orpington."
