As the description already says, this sketch shows what Captain J.C Leach of HMS Prince of Wales has seen before the Hood exploded.

My question is , what distance is 4 cables ?

Better said how long is one cable ? http://forums.ubi.com/images/smilies/blink.gif

Never heard of that unit of measurement until now. http://forums.ubi.com/images/smilies/blink.gif

I take it that this is a old fashioned nautical measurement like phathoms ?

The phenomenon Captain Leach saw is believed to have been a huge cordite fire coming from the 4 inch (102 mm) magazines and venting through the engine room ventilators just seconds before a powerful detonation blew the Hood apart.

From a website I reference for conversions:

4 cable [British] = 741.273 6 meter
4 cable [British] = 0.4 mile [nautical, UK]
4 cable [British] = 810.666 666 67 yard
4 cable [British] = 2 432 feet [international, U.S.]

Poor Hood. I saw a recreation of that battle in some documentary, which makes it seem that her loss was a bit of bad luck. Apparently, she was in a turn and was struck in a weak spot, which had her turn been completed only a few seconds later, would likely not have been fatal. Hood had only half her upper deck ugraded to thicker armour; between her publicity tours and having to wait her turn in the yards, she was only half done when war broke out. Not to attribute her loss entirely to fate or luck; Bismarck's gunnery directors were simply superb. Every account I've read states she broke in two, and amazingly, her fore turret fired off its last salvo while the ship was torn in two, a defiant last gesture as she slipped beneath the waves.

I've heard two accounts.

1. Hood's captain turned too early, before he was out from under Bismark's "plunging fire". The end of a parabola, where the fire comes down through the deck vertically, as opposed to horizontally through the heavier side armor.

2. There was a kink in the side armor, right where the shell hit, right over the magazine. The kink was known about and there was always a plan to fix it, but the war intervened, and then there was no time to fix it as the ship was needed on patrol.

Thanks AndyJWest and gamer025 http://forums.ubi.com/images/smilies/25.gif


There are several theories regarding the Hood's sinking.

There are/were even theories saying that the Hood was sunk by an accident like a malfunctioning munition elevator (The Hood reported trouble with one of them before it left the harbour) causing a fire or a shell exploding inside a gun turrent causing the fire that ignited one of the magazines.

The results of research on the wreck and debris field found no evidence to support those theories and rather point back to the initial finding of a fatal hit by shells of the Bismarck.

Yet the condition of the wreck leaves no evidence to find out where exactly the shells may have penetrated Hood's armor.

This History channel docu shows what Leach saw with the help of CGI (http://www.youtube.com/watch?v=Zbz6Oa5PQuA)

Everything I've read states that the Hood was hit in one of the magazines causing a massive explosion which is why she sank within 14 minutes of contact. I don't know about the turning, shell angle, etc.. simply that a penetrating shot in a magazine would blow the whole magazine and that's enough power to split a battleship in two.

Here is the best detailed technical examination of the loss of Hood I know of. The author, Bill Jurens, is a well-known technical writer and historian, and used to be a regular poster at that website.

My link goes to the main INRO page rather than part 1 of the article partly because there is no "go to next page" at the end of each page and partly because the other articles are also interesting.
