My first article about the newly discovered Bremen Iceberg that appeared in Encyclopedia Titanica in July 2001 (The Iceberg — resurfaced?) was about the photograph itself. This second article concerns another part of the fateful moment of collision: this iceberg picture provides us with a possible answer to the question, why chunks of ice were thrown onto the deck but no damage was caused to Titanic’s upper decks. The conclusion: chunks of ice did not fall from the top of the berg straight down onto the deck – they were thrown upwards then rebounded at the overhang of the iceberg and finally fell onto the ship.

The common view is that the top of the iceberg threw chunks of ice straight down onto the deck 1. It is also the common view that there was no extreme overhang at the berg which has reached over to the ship straight above the deck. Regarding both aspects it is hardly possible that ice was thrown from an icebergs top which was NOT hanging over the deck: furthermore it is widely known that the upper decks did not even touch the berg. According to these points, this must mean that the berg would have thrown its ice some way horizontally over to the ship. And we can furthermore assume that the size of the berg maybe did not reach up to the upper deck2. The witnesses reported very different sizes and even Rehoreks photograph doesn´t give any clue to that question.

How much ice was fallen onto the deck? The Able Bodied Seamen William Lucas has been examined at the British Enquiry (Day 3) by Mr. Rowlatt:3

Rowlatt: ”Where did you see the ice on the deck?”
Lucas: ”On the fore-well on the starboard side.”
(...)
Rowlatt: ”How much ice was there on the deck there?”
Lucas: ”I suppose, about a couple of tons.”

However we have very different witnesses reports. Fourth Officer Joseph Groves Boxhall was examined from the British Enquiry to this point as well (Day 13):

Mr. Raymond Asquith: ”Did you then go up again through the other decks as far as C deck?”
Boxhall: ”I came up the same way as I went down.”
Asquith: ”Without noticing any damage?”
Boxhall: ”I did not see any damage whatever.”
Asquith: ”When you got to C deck did you see some ice there on the deck?”
Boxhall: ”Yes, I took a piece of ice out of a man's hand, a small piece about as large as a small basin, I suppose; very small, anyhow; about that size (Describing.) He was going down again to the passenger accommodation, and I took it from him and walked across the deck to see where he got it. I found just a little ice in the well deck covering a space of about three or four feet from the bulwarks right along the well deck, small stuff.”

Boxhall was the only witness who described a bit more precisely the quantity of ice he saw on deck. Not a ”couple of tons” as Lucas said, but ”small stuff”. The Able Bodied Seaman Thomas Jones testified before the US Inquiry (Day 7), that he went on deck and could see ”some ice”. The Able Bodied Seaman Edward John Buley also reported ”a couple of tons of block ice” to the British Inquiry (Day 16). The Leading Fireman Charles Hendrickson saw ”a lot of ice...on the deck” (British Inquiry, Day 5). But none of these accounts was as precise as Boxhall´s one.

Another interesting statement was given by Lookout Reginald Lee at the British Inquiry (Day 4) after a short talk between the Commissioner and the Attorney-General:

The Commissioner: ”What is supposed to have caused the ice to fall on the deck? Was it some part of the ship, the Titanic, striking the berg above the waterline, or was it something that fell from the iceberg without the iceberg being struck.”
The Attorney-General: ”I should have thought myself that it followed that the vessel must have struck the iceberg, and brought the ice on to the deck.”
The Commissioner: ”So I should have thought, but I was wondering what part of the Titanic would strike the iceberg.”

The Attorney-General: ”I do not think there is any such suggestion.” (To the Witness.) ”You have told us that you saw some ice fall on to the forewell deck?”
Reginald Lee: ”It must have been overhanging from the berg as she struck, otherwise it could not have come there, because there were no yards on the mast or anything of that sort. It must have been.”

The Attorney-General: ”It must have been either the head or the side?”
Reginald Lee: ”It caused it to fall inboard. This is where it landed, just on that forewell deck.” (Showing on the model.)
The Attorney-General: ”You did not notice that, did you. Did you notice whether there was any overhanging part?”
Reginald Lee: ”No, I cannot say what was overhanging; I cannot say the size.”

If we try to get a precise quantity of ice on deck we cannot get a clear result: some witnesses said ”a lot”, some said ”some” ice. But Boxhalls description was the most precise one. Lee´s report is very interesting because he spoke of an overhang he did not see. Was the iceberg somewhat higher than the guard rail or not? Boxhall spoke of an iceberg which was floating very low in the water and probably did not extend above the level of the guard rail. Other witnesses said that the iceberg did. As mentioned above Rehorek´s iceberg photograph doesn´t give any clue about its size. If we assume the iceberg did not reach up to the upper decks, how did the chunks of ice then get onto the ship? As Charles H. Lightoller, Second Officer, explained at the US-Hearing (Day 1):

Senator Smith: ”Was the vessel broken in two in any manner (i.e.: as a result of the collision) or intact?”
Lightoller: ”Absolutely intact.”
Smith: ”And the decks?”
Lightoller: ”Intact.”

Boxhall’s report to the same hearing, after having inspected the ship’s interior, was similar (Day3):

”... I went on the bridge and reported to the captain that I could not see any damage.”

Boxhall repeated this at the British Inquiry (Day 13).

If the Titanic had chipped chunks of ice off the iceberg at the forecastle level, then Lightoller and Boxhall would certainly have spotted some visible damage. But there are no reports from any other witnesses either of any damage suffered by the Titanic above the water line. This is also confirmed by the report of the British court of inquiry:4

”The collision with the iceberg, which took place at 11.40 p.m., caused damage to the bottom of the starboard side of the vessel at about 10 feet above the keel, but there was no damage above this height.”

This must mean that the Titanic did not come into contact with the iceberg in the area of the upper forecastle – but, nevertheless, chunks of ice were thrown onto the deck assuming that there was an overhang, but which did not reach over up the deck? This inevitably raises the question as to how they could have got there. In the Cameron film, in which the collision was reconstructed as accurately as possible, this moment is cleverly disguised: the Hollywood iceberg rises straight up out of the water well above the height of the guard rail, and chunks of ice break away high up and plummet straight (!) down onto the forecastle deck. If the collision had happened as it is portrayed in the film, then the Titanic would most certainly have shown signs of damage in the upper area. After all, the ship’s hull becomes a bit broader as it rises out of the water accordingly some damage caused by the perpendicular face of the iceberg must have been visible higher up as well. In reality, however, in 1912 this was not the case.

Collision Diagram 2

Looking at Rehoreks iceberg photograph, that has shown up in the year 2000 5, we now can state that chunks of ice could still get onto the deck even when the iceberg did not reach the height of the guard rail. On this photograph the face of the iceberg is slightly (not extremely) overhanging above the point of initial impact. Let us just visualize the collision again: the 50,000 ton ship rams the iceberg at full speed. The force of the impact causes chunks of the iceberg to be split away and projected some ice into the air. The smashed edge at the berg is clearly to be seen on the photograph, of course the bigger damage we cannot see on the picture was below the water line.

We can therefore assume that only a few chunks of ice were thrown onto the deck. As we mentioned earlier, Lightoller and Boxhall reported that above and below deck everything was ”intact”, which corresponded to the findings of the British court of inquiry, too. This is also an indication that only the lower sections of the Titanic hull struck the iceberg and that ice was thrown upwards then rebounded from the upper overhang of the iceberg and finally deflected onto the deck. Of course a bigger part of these chunks fell back into the water.

This theory - by the way - does not depend on the size of the iceberg: the rebound effect works with an iceberg that was or was not extending the upper decks.

    All, I wasn't really saying that the iceberg did scratch, I only suggested the possibility. I was more suggesting that when the berg tipped slightly during the collision, it may have only touched the ship very slightly, however enough for some ice to scrape off. On the other hand, perhaps not. There were noises reported. I cannot remember whom these were from in particular, but descriptions like Titanic being opened like with a can opener, dragging a chain along the side or dropping a chain have been described by either passengers or crew. This noise may have been from the grounding, or else from scraping along the side. As for the Cafe Parisien thing, the berg would not have been close to the ship. By the time the iceberg passed this area the stern had already swung away. This is explained in David Brown's book. He gives a good example of Mr. Harder's account. Being aft on E deck, in cabin 50, he saw the berg being about 50 - 100 feet away. Mrs. Clark in C89 saw a white object which I think she thought was a sail ship (i.e. with white sails). If the berg was close she would have simply described a white wall or mass (as Rehims did who saw it through the windows, fore on A deck), however she saw more of it and related what she thought it represented to her. As for the water on the ports at the Cafe, this may well be condensation. Being warm inside and cold outside, some condensation may well have occurred. Daniel.

    Dear Henning and all, I should perhaps reiterate that I am not negating the rebound theory as a possibility. I am just attempting to illustrate that other factors, I believe, played a part in the deposition of ice on the ship and, to a certain extent, the noise as heard by a few. As you mentioned earlier, Daniel, the point of impact with the ship depended on the shape of the berg. For example, we should exclude the possibility that the iceberg simply "stuck out" more on the B-deck level. Spencer Silverthorne, just outside the smoking room noticed "chunks" falling off the berg. I doubt this would have occurred without any prolonged impact with the side of the ship *above* the waterline. If the iceberg was seperated from the ship at this point (at least above the waterline), Silvethorne's observations wouldn't have made sense. For what it's worth, I'm not sure we should take Omont's description of "water" on the ports too dogmatically. I don't want to get into pedantic territory here, but bear in mind that Omont was a Frenchmen. He may have meant "ice". In contrast, Chevre's desription of ice "rubbing against" the windows is pretty self explanatory. Although I'm of the belief that most noises heard by survivors came from the possible grounding as described by David, i.e. lower down (hence descriptions of chains running along the hull, broken propellors etc), it is entirely likely that a few (if not all) were referring to "rumbling/scraping" sounds outside their cabins, or

    Hi all and thanks Daniel for this good locating analysis. Ben: indeed I think the water splashed up pretty high. There was a big mass of a ship running with nearly full speed against another huge mass and there was only a small space between the hull and the iceberg. Indeed I think that some water reached a pretty good height - all chunks which were thrown upwards also were pretty wet of course... I believe that there was not only one initial impact but also an impact leading for some seconds (no news). There was some under water rubbing for some seconds with consequental damages to the lower hull and to the iceberg as well. During all these seconds ice was breaking away and rebounding. And water as well with these pieces of ice. I also see all the points mentioned here to weaken this rebound theory. All I tried is to stay close to the most authentic informations we have, to me these are the eyewitnesses accounts and to find a solution why none of them recalled on which way the ice came on board. Ben, you have convinced me what belongs Omonts account. I won´t take this dogmatic, I now generally think that a single account shouldn´t count. But in my opinion among all witnesses there is a certain lack of accounts telling about an iceberg scraping the upper hull. Best regards Henning
  4. Henning Pfeifer Henning Pfeifer
    ...by the way, Daniel, I think it is a pretty good idea to think about condensation generally. Probably there was some condensation inside the protholes. Specially in rooms where the air humidity was pretty high. I believe that on (in) a ship there is a basically pretty high air humidity inside. Do you think we could state that looking through the portholes generally was handicaped by condensation? This could be an interesting aspect for directors of future films. I only recall clear portholes in the films... Best regards Henning

    I would like to bring up this topic (as it is the only thread that I can find on the subject at Encyclopedia Titanica) to address a couple of points/questions. First of all:[LIST][*]The best images of the wreckage seem to indicate quite clearly that there is no major damage along the outer starboard upper deck (forecastle or well deck) -- and the railing in particular -- aside from buckling damage obviously caused by hitting the ocean floor. Nor was there any damage to the corner of the wall further astern in the well deck. Even brittle ice would likely have at least dented the rail. [/LIST]This next one is a somewhat more complex discussion. [LIST][*]We don't know the y-axis "drift angle" by which Titanic struck the iceberg.[/LIST]What do I mean? When Murdoch was aware of the iceberg ahead, Titanic was turned hard to starboard. At a high rate of momentum, Titanic would have angled during the turn to starboard. When they were clearing the iceberg, Titanic was then turned hard to port. Again, this would have caused another albeit opposite tilt. The measure of that angle would have been dependent upon the surge and sway velocities and how "hard" the turns were. [MEDIA=youtube]k1YxpOg3r6U[/MEDIA]We've seen modern ships demonstrate those tilts during various maneuvers that illustrate just how noticeable that list might be. Consider this video of the U.S.S. Nimitz:[MEDIA=youtube]TN7BjeRad2I[/MEDIA]While the top speed of the Nimitz is similar to Titanic's top velocity, the

    Hello Chris.The big problem about trying to re-create the movements of the ship during the time in question is that almost if not all researchers have failed to factor- in the effect on the bow dirction during impact + 6 seconds. As you know, experiments were made using the RMS Olympic to determing how long it would take for the bow to swing 22.5 degrees.. it was 37 seconds. However, that experiment was flawed, in that it was made with the ship making 21.5 knots and during the turn, her forward velocity was not impeded in any way.I have pointed this out several times in the past but have not had any sensible response. In fct no response whatsoever..Try this little experiment. You can do it with a doorway or by walking parallel aling a kitchen top.It is not rocket science and even a child can do it. I demonstrate in the following rough sketches.
