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

Alberto wrote: I think I remember that the Baron speaks about the dynamic pressure of the water against a fore transversal bulkhead when Bismarck was speeding, forcing the crew to reinforce the bulkhead. Doesn't this point to an explosion tearing a quite large hole (larger than around 14") in the hu...

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...

Re: Bismarck firing procedures at DS

The record regarding the firing at Denmark Strait are so incomplete rendering ranges and bearings at any particular time, especially later in the action after Prince of Wales had turned away, that meaningful analysis is probably impossible. The lack of information on fall-of-shot, etc. essentially p...

Re: Bismarck firing procedures at DS

At the risk of being perceived as overly pedantic, it technically IS possible to get a hit without a straddle. Such would occur if the target were hit by a projectile at either end of the pattern. Straddles without hits, are of course, relatively plentiful. That picky correction being made, the prev...

Re: Bismarck firing procedures at DS

The question " which is the battlemap that, up to now, puts in context all evidences in the best possible way ?" really leads us -- probably inadvertently --into a discussion of historical methodology. The question is, in a strict historical sense, somewhat meaningless insofar as there are several v...

Re: Bismarck firing procedures at DS

No. I suspect his mind was clear enough after the fact -- i.e. when writing post-action reports, etc. If not, he wouldn't have retained command-level positions. But is is possible -- perhaps even likely -- that his memory of precisely how things happened during the action was impaired due to his inj...

In response to Alexandros' memo of Mon Oct 01, 2018 5:59 pm (we seem to have no numbering scheme to enable posts to be identified more easily): I did not respond in detail basically because I have neither the time nor the energy to engage myself extensively in this discussion. It's easy -- as I have...
