@ Paul Cadogan,
nice to hear that you are ok ... watch out for Irma, ... :-)
Without hope to find something ... we were going to be left with Sir L. Kennedy and the Baron book's ... while we have found much more recently on the archives ... and I am sure we will find much more in the future, ... like the Jasper document about PG gunnery at DS for example, ... or the original PG full PK film ... or the PG photo by Lagemann negatives ...
Of course the depth of the ocean ... or the still secreted documents and photos in the UK archives, ... are very difficult things to put our hands on, ... for very obvious reasons.
We will try ... and now we have Wadinga helping us with more time, ... first thing I am thinking of is the IWM - BBC interview of RearAdm W.F. Wake-Walker, ... not available on-line, ...
Sean what about taking a tour a the IWM looking for this one :

REEL 1 Account of sinking of the Bismarck in Atlantic, 26/5/1941: first sightings of Bismarck and Prinz Eugen in Denmark Straits; shadowing of German ships by HMS Suffolk and HMS Norfolk; arrival of HMS Hood and HMS Prince of Wales; sinking of HMS Hood; Bismarck steering south away from pursuers; attack on Bismarck by Fleet Air Arm Fairey Swordfish from HMS Victorious; Bismarck's escape under cover of darkness; sighting of Bismarck by aircraft, 26/5/1941; damage to Bismarck from Fairey Swordfish from HMS Ark Royal; closing for action and torpedoing of Bismarck by HMS Norfolk and HMS Dorsetshire.
If the duration time is only 8 minutes as I suppose, is just a generic summary of the events.
Still, ... it is an historic document we do not have yet.
Of course are important also the Churchill war room documents in this regard, ... still at the IWM :
