Mystery German submarine identified by deep wreck divers

0:00
75 M underwater on the remains of a German first world war submarine I'm
0:06
part of a team of divers who are trying to solve not one but two underwater
0:13
Mysteries the wreck is located off the lizard peninsula in an area that's
0:18
littered with shipwrecks it was a notorious hunting ground for German submarines during the first world war
0:25
but is also battered by Fierce tides and strong currents making it extremely
0:31
challenging to dive if you've watched any of my other videos and of course I hope you have
0:37
you're in for something different this time it's not me wielding the camera it's my friend
0:45
Fran she's got a parall lens mounted on her head and she'll be videoing the dive
0:51
if you see a diver with yellow gloves on that's me as if on Q you're about to see me com
0:59
un to view there I am it's all a bit dangly I've got my camera hanging off me and also
1:06
the small lifting bag that we're going to be using to put on the shot at the end today we're the last pair in the
1:14
water this dive is really well planned there's a group of teams and we've each
1:20
got our own objective to do when we get the to the bottom ours is to go to the
1:26
prop and to try and scrub it and find if there's any information on it you can
1:31
see that's why we've got a bag full of tools and also several cameras to record what we find the other thing that's
1:38
different about today's dive is the shotline it's top
1:43
tensioned I.E it uses a weight in order to make sure that the shotline is
1:49
completely vertical you can see the weight and the shotline coming down from the boy just
1:56
in the top left of the screen the advantage of this set up is that you don't need to travel as far in a
2:02
horizontal distance which you sometimes get when there's a long shotline and a bit of Tide running it's all about
2:10
personal preference really and that's what we decided on that's what the skipper set up
2:15
today anyway we're carrying on in The Descent and you can see that visibility is pretty good there's also a reasonable
2:22
amount of ambient light which is always quite nice this wreck was first dived in 2006
2:30
and found to be a large World War I German submarine using this information and
2:37
Royal Navy syncing reports inis McCartney identified it as the SMU
2:44
95 this attribution stood until some French divers dived on a similar
2:50
submarine which was believed to be the wreck of 95's sister the
2:57
u93 the French divers scrubbed the prop and found some numbers on it that were
3:03
after the launch of u93 but before the launch of
3:09
u95 it was generally felt that props were fitted before launch and therefore
3:15
the suggestion was that the French had found the u95 which meant that this submarine that
3:21
we're diving on today was probably the u93 therefore the first mystery that
3:27
we're trying to solve today is to identify the submarine that we're currently descending
3:33
towards as you can see though Fran's got a problem much nearer to home for some
3:38
reason her camera doesn't seem to be playing she's trying to get that fisheye lens into the right place to take
3:45
photos I'll be honest I admire her bravery cuz that isn't clipped onto her in any way whatsoever the seab bed's
3:53
nearly 40 M below her and if she drops it it's probably gone forever and that's
3:59
quite a bit of money she's a cracking diver though Fran
4:04
and you can see she's obviously solved her problem she's clipping it back on and she's cracking on with the
4:10
dive the other mystery we're trying to solve today is to try and find what sunk
4:16
this submarine in the first world war the Royal Navy received many sinking claims
4:22
from different sources a surprisingly large number of submarines were sunk by ramming or
4:29
although the Royal Navy only credited one merchant ship with doing this that
4:36
was the RMS Olympic sistership of the very famous Titanic which sunk SMU
4:43
103 in May 1918 earlier in the year the SS brail
4:50
had also claimed to have rammed and sunk a German submarine off the lizard Peninsula but this was discounted by the
4:57
Royal Navy part of our mission today is to find out if there's any evidence that this is the
5:05
submarine that was attacked and sunk by the brain Neil before that though we need to do
5:11
our bottom of the shotline admin you can see we're not the first divers on the wreck today there's been
5:17
lots of divers ahead of us and their strobes are on there in fact one diver has already completed his mission and is
5:24
heading back up the quality of this video isn't as good as some of my other ones
5:30
and I apologize for that it's mainly because there aren't any video lights so
5:36
it's just ring on the uh individual torches that we're all carrying Fran just turned her hers on and you can see
5:44
there the submarines starting to come into view pretty much the first thing we see is the deck gun the rest of the thin
5:52
outer Hull has rotted away leaving just the pressure Hull the Germans preferred
5:58
to use deck guns wherever possible Torpedoes were expensive unreliable and
6:04
even a submarine of this size didn't carry many so if they could they'd have
6:10
used a deck gun or a boarding party which would have carried explosive
6:15
charges by the time the SMU 95 was sunk in 1918 though there was significant
6:21
amount of Danger on the uh on the surface lots of fast
6:27
destroyers Q ships with which were merchantmen with disguised weapons on
6:32
board there was loads of small trollers and even at this point airships and planes were being used against
6:39
submarines added together there was a high level of threat and survival rates
6:45
amongst submarines and submariners was really low returning to the dive you can see
6:52
that Fran has spotted the ready use ammunition in between the gun and the conning Tower so we know where we are
7:00
and we're about to swim towards the stern of the vessel our mission is to
7:06
scrub the prop some of the other divers have got different things
7:11
photography photogrammetry these are all tasks given to members of the team and once we're on
7:18
the surface the evidence is going to be put together to try and build a picture of what actually
7:25
happened you can see that the wreck is lying on its port side
7:30
and lots of things have fallen off onto the seabed various bits of pipe and pressure
7:36
vessels that have contain things like air for blowing the ballast tanks I'm in front of Fran but we're
7:43
both moving towards a Stern taking the opportunity to see whatever we can it's really
7:51
interesting people often think that submarines are big and solid and the
7:57
interior of them the pressure h is but the pressure Hull is always wrapped in a
8:03
thin outer coating of metal onto which things are mounted and it's also the bit
8:08
that people walk what that means is that when they rust and Decay underwater the
8:14
outer Hull Falls away leaving the pressure Hull remaining and what we're
8:19
looking at at the moment with all these ribs and stuff that's the remnants of the exterior Hull I.E the not pressure
8:28
bit under it as you'll see is the pressure hle that remains significantly
8:33
intact although later on in the dive we'll see that one of the hatches is
8:39
open and therefore the interior is flooded and probably always has
8:45
been when the brainal submitted its sinking report it claimed after it had
8:50
rammed the submarine to have heard foreign voices in the darkness now we can only speculate but
8:59
those those May well have been German Sailors who'd escaped out of the conning Tower which is where the hatches open
9:06
and were then left to freeze in the water in January
9:12
1918 which is when it was believed to have been rammed now you may think that's pretty
9:18
terrible of the crew of the SS brain Neil not to pick up the submariners or
9:25
the people in the water that they could hear and to be honest viewed from over a 100 years away I
9:32
think that's a a reasonable perspective viewed from the people on board the SS
9:37
brain nail I think that's very understandable so many ships and so many Merchant Mariners had died at that point
9:44
I can imagine the uh they felt the urge to have a bit of
9:49
Revenge anyway we've arrived at the stern and you can see the prop there
9:56
it's actually in a really good position for scrubbing it's standing well clear
10:01
of the bottom so we can get around it on one of my other submarine prop
10:06
scrubbing videos you'll see that we can't get to parts of the uh parts of the prop but this one was really easy as
10:14
you can see Fran's got an ice scraper the kind of thing you'd use for the car it's making short work of the vegetation
10:22
and concretion that's on that uh on that prop I'm next to her you can see my
10:27
yellow gloves once she's cleared the worst bits of it away using the ice scraper she's going to give it to me and
10:33
I'm going to have a go at some of the other blades while she gets out the big brow pad and tries to clear the
10:39
concretion off we know there's three bits of the prop that we need to work on so we're working together to try and do
10:46
as much as possible during the limited time that we've got right there she's handed it over to
10:52
me she's opening up a string bag of goodies in there she's got a wire brush
10:58
and some large gillow pads undoing knots is surprisingly
11:04
difficult wearing 5 mil gloves like Fran got on there but she's actually doing a pretty good job I think the first item
11:11
out is going to be the wire brush yeah here it comes once again she
11:20
going to be uh using that to kind of crack on and clear as much as you can out what we're really hoping for is some
11:26
uh some numbers or an inscription on there only one face had anything on so
11:32
as soon as we find a face with uh with something on we know we can stop doing on the others and and concentrate on it
11:40
very shortly we're going to get the good news that this is the face that's got
11:45
the numbers on it's the best one it's easiest to get to and it's going to be
11:50
the easiest to take photographs of and all that kind of stuff as well so it's just clearing it off at the moment
11:59
although the light's pretty good down here it's not good enough to see the uh the letters or numbers but as soon as
12:04
she shines a torch on there she can see it I've been working on the uh the other
12:10
two faces the ones underneath she's giving me the nudge we now know that we don't need to bother doing that we can
12:16
just concentrate on this one so she can clearly see that there's stuff on there so it's just a case of getting it clean
12:23
enough now so that we can actually read what they say um and this will be the stuff that's really crucial for our
12:29
research so she's got it to a good enough point now wire brush is going
12:35
away there's a big brillopad coming out those are normally used on the props of
12:41
yachts and large vessels one of the team works as a commercial diver so he does
12:48
this for a business and uh he's managed to uh to borrow a couple of these which is what
12:54
we're using now and you can see once again it's clearing all the stuff off and it's going to make it easy uh for us
13:01
to see what's uh what's down there it's actually a really good result we've only been underwater for what 10 minutes
13:08
maybe and already we found the prop with the uh information on that we're going to want and we know we're going to be
13:14
able to clean it up and uh and get the information even better is that this is
13:21
actually the first dive of two that we've got planned so we know we're going to be able to concentrate on this prop
13:27
you can see Fran there sufficiently confident she actually thinks she can read uh read it I'm shining some light
13:34
on for her to to try and help so she doesn't need to bother doing that she's
13:39
she's clearly had enough though so she's going to hand it over to me and going to give me the opportunity to have a go she
13:45
moving out the way you can see there I am she's made some wise choices in terms of gloves I've got dry gloves on which
13:53
aren't the best for this sort of thing I'm probably going to end up with a hole in them and therefore
13:59
uh flooded glove flooded up my arm Fran hasn't bothered with that she's got wet
14:04
gloves on which are much more robust for kind of underwater manual labor it's a
14:10
lesson I I'd like to say I learned but I've done the same on every other prop scrubbing dive that I've been on as well
14:17
there you go you see we're working we're working together trying to expose as much detail as
14:23
possible scrubbing props doesn't make for particularly great videos but I don't like to cut my videos so you can
14:29
actually see what it's what it's like what we're doing while we're doing this though it
14:34
might just be worth giving you a bit of information about SMU 95 it sunk 14 ships over the course of
14:43
six War patrols it was active from June 1917 until January 19 when it was sunk
14:51
which is just under 7 months incredible how short its service history was but
14:58
how much destruction it uh it raked in that time uh I think about 38,000 tons
15:05
of ships so not of a massive amount in the in the scope of the time but still
15:11
you know flicted a lot of damage a lot of misery no doubt the sailors on board the
15:16
SS brainal were well aware of this kind of thing and that's why I don't think
15:22
they showed much Mercy to the German submariners once they realized they were in the water so a brute brutal period
15:30
for everybody involved in this conflict and something that's pretty much forgotten these days I think when we
15:36
tend to think of submarines we tend to think of the second world war all those OTS all those convoys but actually
15:43
there's far more ships sunk in the first world war far more submarines sunk and
15:48
far more people killed so we should probably know a bit more about the first
15:53
world war from a diving perspective most of the ships and the submarines sunk in
15:59
the first world war tended to be closer into Shore so there's the added bonus that there's far more ships and
16:06
submarines accessible by technical divers so from my perspective that's
16:13
quite a good thing I'm never going to be diving ships and submarines sunk out in the middle of the
16:18
Atlantic so we've stopped our cleaning now we think we've cleaned enough to get some decent photos you can see I'm
16:25
actually turning on the video lights on my camera if it would have been nicer if uh I'd have turned those on earlier on
16:31
it it certainly made it easier to see uh with the video give better quality video
16:38
uh Fran's also got out her notebook and I think in a moment she's going to tell me to write down whatever I see on there
16:45
it's really important that we go up with as many records as we can we've got the photos we've got our memories and we've
16:52
got whatever's written down on that piece of paper there I know it can be difficult for people to orientate
16:58
themselves when looking at videos but at the top of the screen here you can see the propeller and the shaft that is
17:04
coming sort of bottom right that's coming from inside the submarine and ultimately goes to the engine so where I
17:12
am at the moment with my yellow gloves that's near the stern and behind me is the
17:17
rudder that's where we've been scrubbing the prop from and that's the uh best
17:23
place for reading the uh the numbers and letters not least because that's the way they're orientated so you can see there
17:29
I've got my camera I've got the video lights I'm making sure that I've got it
17:34
uh I'm getting it all videoed obviously there's something in the way of one of the numbers so I'm trying to clean it
17:40
out the way Fran wanted to have a go at it but I'm I'm not let letting her have any of that earlier on I mentioned that
17:48
the dates on the props are important and they're the things that allow us to have a good guess at what the submarines are
17:56
now once you see me right down the dates on that bit of paper I'm going to go
18:01
into a bit of an explanation about how they are useful and how they allow us to
18:08
have a best guess at which submarine is which first of all though I need to do a
18:14
bit more scrubbing clearly we haven't done a good enough job but you can even
18:19
in this video now you can see how clear the letters are I wonder if the people who fitted this prop over a hundred
18:26
years ago had any idea that the next time those letters and numbers would be seen would be by some
18:33
divers on the wreck and that they would be used to identify the submarine and
18:39
therefore the last resting place of the 34 men and four officers who went down
18:44
when this boat was sunk I'm ex Army and I've served in Conflict nothing like the
18:51
first world war of course but I do feel a sense of kinship with the people who lost Lo
18:59
their lives fighting for their country I don't agree with their cause and we would have been on different
19:05
sides in the uh in the conflict but the fact is you've got to feel for people
19:10
who died while fighting for their country these would have been young men
19:16
with their whole lives ahead of them and all of that was gone part of the waste
19:21
of War I think don't think there's much appetite amongst German people to find
19:27
out what happened to relatives who died and were lost in the first world war but if there are people out there looking
19:35
it's nice to think that by identifying this wreck we'll have helped them find
19:41
out where their relative is this is actually really hard work scrubbing props like this and you can
19:48
see I've swapped from my right hand to my left hand so I'm starting to get fatigued you can also probably see that
19:54
the actual brass is starting to come through or probably bronze I'm sure someone will correct
19:59
me as you can see this isn't a particularly exciting job and there wasn't a big queue of people to do it
20:06
but there's other people other members of the team who are doing jobs that aren't particularly interesting either
20:11
one of the guys is swimming up and down with a video camera trying to get every
20:16
part of the wreck and that is going to be stuck into a computer later on to do some
20:22
photogrammetry and as you'll see towards the end of my dive that proves really useful because one of the things it does
20:28
is give us a really strong clue as to what sunk the wreck I'm not going to
20:34
steal the uh I'm not going to steal the Thunder from later on just to say I
20:39
think it's a really good clue so if you hang on towards the end of my video you'll see that clearly Fran's getting
20:47
bored with just providing the light she's also dived in with the wire brush
20:53
to try and help I think both of us are at the point now where we just just want to get this
20:59
part of the task done clean it off get the numers sorted cuz once we've done that we can swim around the rest of the
21:05
wreck I think we all want to have a good look around it neither of us has dived a submarine of this type before so it' be
21:13
a really interesting interesting thing to do we've obviously seen the gun already we've seen all the ready use
21:20
ammunition we've been past the conning Tower those are all areas that we both want to go back to but first things
21:26
first got to get the numbers sort got to finish off our mission and make sure that we go back up with the
21:32
information that the rest of the dive team need so I think we're pretty much there so
21:42
I've just asked Fran to uh to take some photos I'm going to be taking some more
21:51
photos I'm trying to get real closeups there I want those photos to be as high
21:57
definition as POS possible so if there's any ambiguity we can zoom in on them or
22:03
whatever I'm not sure where Fran's going maybe just have a look at the uh have a look at the wreck where she is at the
22:10
moment is is what would be underneath a submarine you can see that that uh piece
22:15
of metal that's the skeg that would stop the prop banging on the bottom and the rudder was actually off to the left hand
22:22
side uh okay you can see I'm writing down the numbers now Fran's putting all the kit away um so I think we've decided
22:30
that we've done enough scrubbing for one day uh certainly I've seen enough video of
22:35
scrubbing not nearly as exciting as actually doing the scrubbing there you go you can see what I've written on there u93 to 98 and the date Tech 25th
22:45
of January 1917 that's what's written on the prop those are the crucial pieces of
22:50
information we're going to take up with us but good news we finished so we can
22:56
now crack on there's the prop Sha you can see going back into the hull uh Fran's going to obviously put that
23:03
notebook away somewhere we don't want to lose it with that vital piece of information in while she's doing that I
23:10
think I'm probably taking some photos I seem to recall that I got a really good one of her at this
23:18
point Fran's also a really Keen photographer and although she doesn't have any Lighting on this rig there's
23:24
actually sufficient ambient light down here for her to get some decent photos
23:30
it's also quite handy that I've got video lights and I'm lighting up the area what you can see she's doing first
23:36
of all though is sorting out the white balance if she doesn't do that all her photos are just going to look red from
23:43
the Torches so there you go she's just sorted out the white balance you saw it go from red to White she's now getting a
23:49
few snaps that's me with the uh with the prop or really just I guess going past the rudder and we're now going to go
23:57
over the top of the of the wreck it's actually really pretty you can see there's dead men's fingers all over it
24:04
there's a high level of marine growth almost certainly this is due to the strong currents that pass over this
24:10
wreck several times a day they keep it clean by getting rid of any dirts and
24:15
also provide a high level of nutrient for the animals that grow on the wreck just there on the seabed you can see
24:21
there's some moing ballards they would have been on the outer Hull of the wreck
24:26
which clearly as it's deteriorated they' fallen off there's a couple of divers
24:31
down the other end France taking the opportunity to get a photo and then we're swimming back along the hull back
24:37
towards the gun that we saw earlier and the conning Tower you can also see there's H there's a fair bit of ropes
24:43
and stuff on this wreck almost certainly it would have been potted by local fishermen and therefore they'd have
24:49
they'd have got stuff Tangled and it would have been abandoned here not too many Nets though which is uh which is
24:55
really good and quite unusual it's uh relatively rare for a wreck in this area
25:01
not to have loads and loads of netting on it you can see there Fran is just getting close to the gun I'm not sure
25:08
what that circle is on the deck all sorts of bits of machinery and stuff you can see inside the hull and there is the
25:15
gun uh I believe that's an 88 mm I think there's one of these on the stern and a
25:21
slightly larger 1051 uh forward of the conning Tower I don't think we ever get there on this
25:27
dive though we did do on the uh on the second dive when I look at things like this I just wonder how many times it was
25:35
used in Anger how many ships did that gun sink I'll wager it was uh quite a
25:40
few now it's just really pretty and then we're back to the stern of the gun is
25:47
going to be all that ready use ammunition that we saw on the seabed uh for those of you don't know
25:53
the submarines in this period they had shells in effectively sealed containers
26:00
that were kept underneath the deck so between the outer deck and the pressure Hull and they were there for when they
26:07
got to the surface and they needed ammunition quickly they would literally lift up the floorboards of the deck
26:14
access the ammunition take it out of its waterproof container they could then fire it and then dispose of it once it
26:20
was done and you can see there there's there's there's racks and of them lying on the deck I don't know how many there
26:25
is maybe 30 40 I guess quite a lot anyway which probably shows the you know
26:32
the amount an indication of the amount of times they thought they'd be required uh France decided to get a photo of me
26:37
and the ready use ammunition that's all good and just behind her is the uh is
26:43
going to be the conning Tower and I think that's the next item on our agenda is to go up and have a look at it have a
26:48
look at the periscopes and the hatch that I've already told you is open like
26:54
the rest of the submarine the conning Tower was part pressure Hull and and part outer skin so lots of the debris
27:01
that we can see at the moment or lots of the valves and fittings and stuff would have been in between the outer skin and
27:07
the uh the pressure Hull so it's one of the things when you look at submarines they don't look like you expect them to
27:13
look and that's because the the outer skin that you've normally seen in pictures is gone and there's only the
27:19
inner pressure Hull left the first few times you dive on older submarines this
27:25
is quite confusing and it's not until someone points it out and explains why they look the way they look did it all
27:32
make sense so once again bit of outer skin there that we've just seen there's the
27:39
conning Tower off to the left hand side and Fran is going to go up on top at the front of it as you'd expect is some
27:45
periscopes there's also actually a little uh observation post quite difficult to see but it it was there and
27:53
that would have allowed the uh the people inside to uh to get some observation without using the par scope
27:59
Fran's at the very front of the conning Tower one of the two periscopes is in front of her she's going to swim behind
28:05
them in a second and uh you can see I'm already there looking into the hatch the hatch is interesting as I've already
28:11
mentioned because it is open now I don't think that's something that would have been very easy to do from any depth
28:19
certainly a diver couldn't have opened it it's just too difficult to do especially if there was pressure inside
28:26
so I think it's fairly reasonable to say that this this hatch was opened either when it was sinking or very shortly
28:32
after it was sunk you can look inside and you can see that the hatch into the rest of the submarine is open as well to
28:39
me this just looks like a load of people trying to get off a submarine as it was sinking all the hatches are open
28:46
everybody's just trying to abandon ship as quickly as they possibly can um certainly no diver would have got in
28:52
through the hatch that Fran is currently sticking her camera inside and you it wouldn't be possible to open it uh I
28:59
think that hatch opens downwards anyway with the seal on the the other side of it so this this has been opened from
29:05
inside the submarine and I think it offers a fairly compelling level of evidence that the uh that the crew
29:12
abandoned this submarine as it was sinking
29:17
um really sad to think about that of course it's January water's freezing
29:23
cold and they're then into the sea if we believe that the SS brainal sunk it and
29:30
rammed it then even the poor guys who managed to survive and get out are then
29:35
going to freeze to death or very quickly drown in the cold weather that you would get on a uh on a January day it's really
29:43
sobering to think to think about that this dive is in June I'm wearing a load
29:49
of layers underneath my dry suit I've got an electric heating system and even
29:54
then towards the end of my dive I'm going to start feeling cold I can't imagine what it would have been
30:00
like in oil skins or whatever they wore inside submarines which presumably wasn't very
30:05
much as I think they were kind of Fairly hot noisy spaces and then to go from that into uh into a January sea at
30:13
night just doesn't even bear thinking about so Fran's continuing to record
30:19
take pictures once again you see she's doing it without any light it just shows how much ambient light we've got down
30:25
here even at 70 m it's a it's a really really nice day it's a really good
30:31
conditions for doing a dive like this even now there's no light her torch isn't on um and you can see that there's
30:40
you know enough light to to to kind of make out where you're going anyway she's got a torch back on I think she's just
30:46
looked at her computer a few times she realizes that it's getting towards the end of the dive so it's time to head
30:53
back to the shot we were the last pair on this dive and one of our asks was to fill up a
31:00
lifting bag small lifting bag that's attached to the bottom of the shot and that's just to help the skipper get it
31:06
back on board the boat whilst we're doing our decompression so she's looking for the
31:11
shot now it's not actually where we left it it has moved and if you have a look
31:18
uh when we do find it in a minute or two you'll see that it's slowly bouncing along the seabed this is one of the
31:23
issues with a top tension shot once the current starts picking up up or you get a bit of waves the uh the top tension
31:31
will actually reduce the weight of the shot and therefore make it easier for it to to be moved um you just got to be
31:39
careful of that normally you'll have seen on my other Dives we actually tie the shot into the wreck we didn't do
31:45
that on this dive and uh I'm not 100% certain why um it was just the protocol
31:51
we agreed but anyway you can see that Fran spotted the strobes she spotted the shot and you can see that uh that
31:58
lifting bag that I carried down with me I left it down there ready for exactly this
32:03
moment you can also see the shot is uh is dragging along the seabed you see
32:09
there's a bit of T it's under a bit of tension there the current must be starting to pick up so and you can see
32:14
the drag marks in the uh in the seabed there as well clear evidence it's moving
32:20
so Fran's going to go down she's going to uh unroll the lifting bag and there's
32:26
a little crack bottle on it that she's going to fill and that will uh she's not going to completely fill it just enough
32:33
to make it easy for the skipper to start moving it start lifting it and then once
32:39
it uh once he gets it off the seab b a bit obviously boils law will come into effect and it will start to expand and
32:46
expand and then the uh it will make it easier and easier till eventually it it goes all the way up to the surface
32:53
there's the crack bottle on the dsnb you can see she's putting a little bit of air in not enough so that actually lifts
32:59
off the bottom as I said and there we go she's uh she's heading back up you can see there's a little bit of gas in there
33:06
maybe it's I don't know a fifth full there I am uh arms on my uh on my video
33:12
lights everywhere I could probably do to tuck those in no doubt that's something I'll do on My Deco stop and we're
33:18
starting to uh starting to head back up now next item on the agenda is going to be to uh to collect our strobes and then
33:25
we'll be ascending up towards the towards a l easy shot as we come up you can see it's getting lighter and lighter
33:32
which is uh which is always nice you get a real sense of going home when the uh when the water starts to to to lighten
33:39
like that I also haven't turned my uh my camera off um once again that's all
33:46
admin that I'm going to do when I get up onto the shop so there are our strobes by the looks things Fran has dropped
33:53
down onto mine I think I'm going to let her get it first
33:59
and then we'll go from there in fact that looks as though there's somebody else's strobe so it would appear that somebody else has left their strobes on
34:06
the uh on the shotline don't know why that is um we're definitely the last
34:11
divers off the wreck so uh don't know what's going on
34:17
there so we're uh we're heading back up again all up towards the surface and I
34:24
guess it's probably useful now to kind of talk a little bit about what we found no
34:30
doubt you're all uh you're all interested in that so what did we know well we knew
34:37
the launch date of SMU 93 we also knew the date from the prop
34:43
that had been scrubbed in France which was the 10th of January 1917 so after the SMU 93 had been
34:53
launched it would therefore seem that it probably wasn't the SMU
34:59
93 we also knew the SMU 95's launch date which was actually the same date as on
35:06
the French prop perhaps they were the same and that's why a lot of people thought that the one in France was the
35:13
SMU 95 it wasn't until we scrubbed our prop that we found a new date the 25th
35:21
of January 1917 also after both submarines had been
35:27
launched looking at these it seems really obvious what the answer is that props were
35:34
fitted after the submarines were launched based on this I think we can
35:41
safely conclude that the submarine of France is the
35:46
u93 and that was always where it was believed to be and the one of Cornwall
35:52
is the u95 as inis McCartney had correctly predicted did in
36:00
2006 that's pretty good news everything's where it's supposed to be
36:05
so the other question we set out to find is what
36:11
sunk what we now know to be the SMU 95 and that wasn't something that Fran
36:17
and myself solved that piece of the puzzle seems to have been delivered by
36:23
another one of the divers the video that they've taken of the entire wreck has
36:29
been uploaded into a powerful computer and using a technique called
36:34
photogrammetry a 3D model has been produced this 3D model shows a deep
36:41
crack in the pressure Hull just forward of the conning Tower where the SS
36:47
brainal reported that it hit a submarine although not
36:52
conclusive we believe this provides further proof of the brain ne's claim
36:58
that it had rammed and sunk the u95 it's sad that this contribution to
37:05
the war effort was never recognized during the lifetime of any of the participants but I'm pleased that we've
37:12
been able to write this wrong and that the historical record will now correctly
37:18
show exactly what happened during the night of 7th of January 1918 off the
37:25
lizard peninsula I hope you've enjoyed watching and listening to this video I'd
37:31
also like to thank Fran for allowing me to use it as always I'd love to read
37:37
your comments and I very much hope you'll watch another one of my videos thank you
