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.

Re: Hits on PoW and Bismarck

Turning a properly designed spin-stabilized projectile 'sideways' is actually quite difficult to do insofar as it generally requires a rather large and sustained force exerted from a location that creates a significant offset between the center of mass and the center of pressure. Water can do this b...

Re: Hits on PoW and Bismarck

I am dismayed at the reliance being placed on secondary sources as primary reference material. While the summaries provided in secondary sources are sometimes valuable as background information, one must remember that for the most part they really only represent lay-level summaries often edited and ...

Re: hits on PoW and Bismarck

For what it's worth, I consider Herr Nillson to be an extremely reliable, knowledgeable, and reasonable commentator. I do not consider the captioned photograph(s) from the Hood website as very reliable sources. I examined the bow area twice, once in 2001, and once again about a year later using the ...

Re: hits on PoW and Bismarck

I can't clarify much. The last serious effort I made to go over this data was several years ago now, and memory -- at least very detailed memory -- fails. Certainly nothing new seems to have been added since that time, i.e. there have no new documents, etc. discovered since then. So although I did r...

Re: hits on PoW and Bismarck

I should perhaps clarify things somewhat. There are so many various and sundry holes in Bismarck's bow that it is extremely difficult -- in my opinion practically impossible -- to correlate any pair, one to port and one to starboard, as being caused by the same projectile, etc. There was, and remain...

Re: hits on PoW and Bismarck

I do not personally believe that the identifications of the supposed entry and exit holes for the hit in the bow of Bismarck as shown on the Hood website, etc., are very reliable. This is, one might remember, the expedition that long-championed a more-or-less entirely imaginative interpretation whic...

Re: Bismarck firing procedures at DS

It is important, I think, to keep in mind that the track charts as published in the secondary literature, etc., are primarily intended to be schematic in nature, i.e. illustrative, rather than in any sense technically definitive. One of the problems of producing a track chart, when one is demanded, ...

Re: hits on PoW and Bismarck

Close examinations of the ship's plans coupled with a reading of written and oral descriptions suggest that the projectile approached at a relative angle of about 250 degrees, i.e. from about 20 degrees aft of the port beam.

Re: hits on PoW and Bismarck

Bismarck was hit only once in the bow, not twice. The best evidence would suggest that if projectile in question detonated at all, it did so on or slightly outboard of the shell plating on the disengaged side. Whether the projectile exploded or not would not likely have led to any significant differ...

Re: Bismarck firing procedures at DS

I would concur completely. In my opinion, the the problem, though not ENTIRELY intractable, is really not well-enough defined justify any more sophisticated analysis. Programs to do this do exist -- I have used them -- but anything other than a very crude approximation would not be very useful or ap...
