Re: 38 cm shells

regarding 'light' vs 'heavy' shells and deck penetrations, as is usual It's very difficult to generalize. Really, each situation needs to be analysed on a case-by-case basis. There is certainly little-to-no justification to assume that lighter projectiles will in some way 'wobble' more as they trave...

Re: Hits on PoW and Bismarck

Before casting judgement, if indeed we can, let us wait until Wandinga has an opportunity to present his arguments and evidence, if indeed they are as you purport them to be. I don't mean to be argumentative, but I find your statement "PoW salvo plot irrefutable range closure proves that Bismarck ne...

Re: Hits on PoW and Bismarck

Bismarck's track charts of the Denmark Strait action have, of course, not survived. Nor has that of Hood. The Prinz Eugen and Prince of Wales have survived, and probably serve as the best overall references. In general, should discrepancies appear, it would seem reasonable to assume that the POW tra...

I must admit that at this stage, I am no longer sure what the arguments actually ARE. Certainly the implication that that a painting, apparently made by someone w...

Re: Bismarck construction flaws

At the risk of being picky, I might point out that the interpretation of the angle of fall in the previous diagram as about 19 degrees is incorrect, and represents an error very commonly made. When one is looking at transverse cross sections (I assume that it is indeed part of a transverse cross sec...

Re: Hits on PoW and Bismarck

My thanks to Herr Nilsson for posting the diagram, which helps to confirm my earlier presentation regarding shoring and flooding boundaries, etc. I was very impressed upon my visit to Bismarck, and my examination of subsequently obtained videotape of the Bismarck wreck with the elegant and well-thou...

Re: Hits on PoW and Bismarck

Regarding bulkhead construction, one would have to examine the ship's drawings to confirm thicknesses, etc. and admittedly I have not done this, although I have the data here to do so. That being said, in general, bulkheads, as might be expected, are designed to withstand hydrostatic pressure where ...

@ Byron Angel:

A close reading of the immediately previous memos on this thread will enable readers to determine from whence most of the animosity springs.

Re: Hits on PoW and Bismarck

For what it's worth, I see nothing very remarkable in the relative range and bearing rate plots, which I placed on my track chart of the action long before this discussion began. The relevant track chart will, of course, appear in the upcoming book. From 0555-0603 the range rate seems to have droppe...

Re: Hits on PoW and Bismarck

As the tone of the discussions has improved a bit, I will -- for better or worse -- attempt a re-entry into the discussion. The main point of contention here seems to revolve around the angle of approach of the projectile which passed through Bismarck's bow. In that regard, I must admit that I find ...

Re: Hits on PoW and Bismarck

It IS hard to stay out of this... Antonio recently posted a profile and asked "Am I missing something?" The short answer is 'yes'. A few things. The first is that I don't really think the profile drawing is mine. It doesn't appear in my files listings anywhere, and carries no 'C' number. So, althoug...

Re: Hits on PoW and Bismarck

I said I would refrain from further postings for a while, but just for the record, the uncredited map put up here a few memos ago is mine, prepared, I think, for my Warship International article on the Loss of HMS Hood. I have published it, or near variants thereof, to accompany various and sundry o...

Re: Hits on PoW and Bismarck

Although I could add more, due to the consistently belligerent and demeaning tone of correspondence -- mostly in my perception coming from the "Italian" side of the discussion -- I honestly feel that further discussion of this issue -- unless the tone changes dramatically -- is unlikely to be produc...

Re: HMS EXeter post Graf Spee shell hits 'drawing/s'?

Very complete drawings and descriptions of the damage suffered by the British cruisers during the action with Graf Spee can be found in the British archives. If my notes are correct, they can be found in ADM 267/145.
