The *Prinz Eugen/I] oil thread made me remember an old question which AFAIK has never been discussed here, though elsewhere it has. Which German ship struck the fatal blow on the not so mighty Hood?
Eugen did hit Hood early on, and started a pretty big fire. She is supposed to have adjusted to engaging Prince of Wales when the loss occurred, which is why any chance of her having fired the fatal shot is discounted. However, she fired several salvos at Hood before changing targets.
As the actual cause of the loss has not yet been ascertained, is it possible the fatal shot was in fact fired by the cruiser? The two possibilities are of course that the explosion was caused by the fire alluded to above, maybe due to the trunk doors being opened, perhaps by a shell?
In addition, British closed range before the loss, to about 15,000 yards. That makes deck penetration (the only feasible way a shot could get to the 15 inch magazines) less likely by the 38 cm SK C/34 naval gun of the Bismarck but its just at perfect range for plunging fire by the 20.3 cm/60 (8") SK C/34 of the Eugen, the Hoods deck armour was only 3 inches at maximum, while the penetration capability ay that range was 10 cm (4 inches).
