JW411. Thank you Sir. You have answered my main queries,why,where and when. I have a pewter tankard given to my uncle by the crew inscribed.
"From the grateful crew of Blenheim V5526 608 Sqn." also a photograph of the pilot aboard HMS Westminster. The story as I was told,that having ditched the crew were in some difficulties,and my uncle dived over the side and swam to the aicraft to help them until a rescue boat arrived. The pilot wanted him to be commended, but the 1st. Officer put him on Captains Report for leaving the ship without permission!
Thanks again,it will help fill out another corner in the family history.
