HMS Phoenicia (Malta)

My father served as a diver In the 50s in Malta on HMS Phoenicia, I am after information on the base. I have a couple of photos but not much else.

Any info would be appreciated

Cant find much on the usual Wikpedia, Google engines
My Father was a diving instructor based on Manoel Island in the mid 50’s. I will look for the photos he had and send them to you on here. His name was Roy Falk.
Kind regards
Caroline Falk
