it is easy now knowing all the events and their correlations to find more confirmations on the available books.
On the book : Engage the Enemy More Closely: The Royal Navy in the Second World War by Correlli-Barnett editor W. W. Norton & Co.; 1st edition ( May 1, 1991 ).
In that book we can find the story of this Court Martial attempt by Adm Pound mainly connected with RearAdm Wake-Walker failure to re-engage the Bismarck at pages 298-299. To be noticed that Correlli-Barnett does not reference to Kennedy book, but directly to Adm Tovey original letter to S. Roskill ( dated Dec. 14, 1961 ) preserved into the Churchill archives folder 4/17 with the footnote 43 on page 928.

Correlli-Barnett is a British historian still alive.
Going back to Stephen Roskill it is just enough to read into his book : Naval Policy Between the Wars: The Period of Reluctant Rearmament, 1930-1939 first published on 1976.
At pages 463 and 464 there is a clear description of Adm Sir Dudley Pound personality, directly from who, like Stephen Roskill, served under him for five consecutive years from the on the fleet up to the Admiralty.
The last statement of Roskill about Adm Pound is of particular interest for this story :
... and that he ( Adm Pound ) loved " schedules and Courts of Inquiry " (1) an opinion with which this historian, who served under him for five consecutive years on the Mediterranean fleet Flagship and the Admiralty 1937-41, fully agrees.
That statement correlate to the footnote 1 that I have first found about S. Roskill contradicting Sir L. Kennedy on 1976 and declaring Adm Pound " addiction to enquiries" with the above statement that is more than enough to declare his personal opinion on the Court Martial attempt for the Denmark Strait declared to him by Adm Tovey.

Everything is confirmed by Robin Brodhurst book : Churchill anchor - The biography of Adm Pound edited on February 2001.
On the pages from 178 until to 183 there the same story with the Court Martial attempt ( page 180 ) and of Churchill continuous presence on the phone from Chequers and directly in the Admiralty ( footnote 12 - page 298-9 Correlli-Barnett ) war room keep on referring to the Troubridge event ( footnote 13 - page 296 J. Colville, The fringes of Power, page 391 ).
I have never read about a description of the events and the presence into the Whitehall Admiralty war room during those days better described before on a book.
