Came across some paintings by Leonard Rosoman, a well regarded painter who created haunting, vivid images. He was an artist attached to the British Navy from 1944 and visited Hong Kong shortly after the war, where he painted some wonderful pictures.
He did at least several of sunken ships in the harbour: http://vads.ahds.ac.uk/large.php?uid=66889&sos=5
