I have read a few posts about Schwieger's description of flames and smoke. It would appear there is considerable reason to think the account may have been altered,but even so it would be reasonable to assume that anyone altering it would only change whatever they felt was bad about it. I don't really see how adding an account of flames which had not been in the original would improve it. Even if there were circulating stories about what had happened which were by then thoroughly embellished, why add them to an original account?
I have also read accounts of navy ships, particularly destroyers at Jutland, which showed flame from the funnels at night, or which could not steam at maximum for fear of showing flames. Lusitania is a bigger ship, so more distance from the boilers to the top of the funnel, but how far up the chimneys would flames reach even in normal operation?
The engine room was under orders to be ready for maximum speed at a moments notice. It took hours for a coal fired ship at this time to build up to maximum speed. I don't know anything much about the details of controlling the fires in these boilers, but I would presume that in this situation what the stokers would do is build up the fire with as much burning coal as they dared, and then close dampers on the fires to stop it actually burning away. Then for instant and sustained steam, open the dampers and away. Forced draft was used on warships by pressurising the boiler room to increase air flow through the fires. The boilers were running at about maximum steam pressure.
So what i wondered would happen if there is suddenly an explosion with at least blast extending into the boiler room? Presumably the blast would send air roaring through the boilers and up the funnel? A likely consequence would be flames and clouds of smoke appearing from the funnel?
Quite possibly those on deck were not looking upwards and would not see it, but Scweiger from a distance would see...'a very large explosion with a violent emission of smoke (far above the foremost funnel).'
There might be some issues with exact translation of the original, but an account saying there is smoke above the funnel, is not one saying smoke rose from the decks to above the funnel. Depending on the timing, If there was a waterspout from the torpedo in the air, it might not have been possible for Scweiger to see the region between funnel top and deck to realise the smoke and flames did not originate from the deck.
I guess there wasnt much wind at the time, as the sea seems to have been calm, so perhaps the greatest wind would have been from the ships own movement, which would have tended to blow smoke backwards. Even so a sudden big cloud might have spread forwards around the bridge. I don't know what accounts you have of reports of smoke about the upper ship?
Scwieger also describes 'the superstructure above the point of impact and the bridge was torn apart, fire breaks out, a thick cloud of smoke envelops the upper bridge'. Clearly there was damage to the side of the ship above the water line from the torpedo strike. People on deck could see it. I don't know whether it is a reliable or otherwise account, but I have seen a description of damage to number 5 boat, which if so means there might have been at least some blast damage and wreckage which Sweiger might have seen from a distance and thus explain his account.
Lusitania continued at speed and attempted to turn landwards immediately after being struck. Although they lost power, it would seem they closed the land somewhat before sinking, so presumably did manage to turn. meanwhile, their speed also was carrying them past Scwieger, so his viewpoint would change from looking towards the starboard bow side, possibly to viewing the port stern side, as the ship turned and passed.
There is an incidental issue over gold painted or blacked out nameplates. I have seen a suggestion that the bow names were painted out but perhaps not the stern?
This is becoming a bit of a portmanteau, but i also read some posts here about whether or not Lusitania was an officially sanctioned target and just note that her known movements, expected arrival time, were being transmitted to the german submarines by radio amongst movements of other potential targets.
