I realised I have been very close to "Kangaroo field" a few years ago, when I was trying to find traces of "B8 Sommervieu", one of the many Advanced Landing grounds. The site (Sommervieu) can still be recognized from the Arromanches to Bayeux road as a large flat area.
I am surprised the airfield isn't shown on the "trace" Tony posted, as it is right in the middle of the routes drawn on the trace (it is shown on the pic Mark posted in post 12 of this thread). Sommervieu was active from 22 June, and allthough I am not sure when it was abandoned, I presume it was still active when the Priests were converted in a field nearby.
Attached is a pic of Sommervieu (Kangaroo field marked in orange)
