It is well worth reading Hennessy and Jinks’ “The Silent Deep” as it puts Corporate into context with Cold War operations. Whilst it is probably incomplete in some respects it does contain an unusually large amount of detail about post war RN submarine operations. Whilst I cannot claim to have extensive knowledge of the subject, I can say that there is information in the book that was TS when I last saw it.
No doubt there are gaps in their account, but I believe it is the best record so far of sub surface operations during Corporate,
