All language subtitles for The Lost U-Boats of WWII S01E01 1080p WEB h264-EDITH_track3_[eng]

-During the Second World War,

the Nazis looted everything
they could get their hands on...

including an estimated 600 tons
of gold, thousands of artworks,

and millions
of priceless artifacts.

While some of this
has been found,

much of it
still remains missing.

One man believes the answer
may lie

at the bottom
of the Caribbean Sea.

-By 1945, Hitler knew
he was losing the war.

And he needed to smuggle wealth,

people, and secrets
out of Europe.

And I believe that he took
some of these treasures

and loaded them onto
specially outfitted U-boats.

And I think that I know
where they are.

-Darrell Miklos
began treasure hunting

when he was just 7 years old,
accompanying his father, Roger,

who discovered coins
and other objects

worth millions of dollars.

But by the 1980s, locating
treasure-laden Nazi U-boats

became Roger's obsession.

-It's sitting in British waters
in the Caribbean.

-My dad came across
a one-of-a-kind blueprint --

one of only nine
modified U-boats.

The blueprints show that
the torpedoes

were actually removed
from their chambers.

Why would you remove
your best defense measures

if you weren't
gonna use the space

to carry something
much more valuable?

My father searched
for these U-boats

until the day he died.

But I have something
that he didn't.

Last year, I had a close friend
of mine

approach me with a chart.

Now, this chart was given to him
by a former

U.S. Navy pilot,
and that pilot's job

was to hunt out
Nazi U-boats in the Caribbean.

He drew up his own chart,

and it shows the location
of not one, not two,

but seven possible U-boats

located in the Caribbean
near the Dominican.

-Armed with this naval chart
and cutting-edge technology,

Darrell has assembled
a team of divers and experts

to pursue his father's dream.

-I'm looking for answers.

Can this chart lead us
to modified U-boats?

Were they carrying
valuable treasure and secrets?

Where were they headed
and why?

-It's taken five months
of preparation,

but Darrell Miklos and his team

are finally headed out
on their mission.

They're departing
from their home base

in the port of Montecristi.

-Load the tanks first, guys?

-Their goal -- dive each of the
seven target sites on his chart.

♪

The team has a limited
weather window.

So they need to optimize
the dives

to the most
promising sites first.

-Captain, thank you.

We are undergoing

an exploration of seven --
seven targets, okay?

And this here is the chart

with the actual coordinates
circled here.

-Why is there such
a concentration

of these wrecks in this area?

-That was my first question
when I first saw the chart.

This area at one time was a war
zone -- a secret war zone.

There was a war
that took place here

between the Allies
and the Nazis.

-During World War II,

the Caribbean
was a major naval battleground.

The Nazis sank some 400
merchant ships,

all in an effort to control
shipping lanes bringing oil

and other vital supplies
from the Caribbean

to the U.S. and Great Britain.

Toward the end of the war,

many believe
that below the surface,

the Nazis also secretly
used these lanes,

only they used them to move
treasure, military plans,

and high-ranking officials
from Europe

to South America by submarine.

Darrell believes
some of those U-boats

could have ended up
here on his chart.

-And so what we have here
is a high concentration

of U-boats, okay?

We've already done magnetometer
surveys of this area,

so every target number
that you're looking at

has mag targets
associated with it.

Deploying the mag.

-Just two days ago,
Darrell worked

with a magnetometer specialist
to survey most of the targets

identified on the U.S.
naval chart.

A magnetometer
measures disruptions

in the Earth's magnetic field,
caused by the presence of iron,

to detect metal objects
or structures

located on the ocean floor.

-It's logging in the actual
GPS coordinates.

-Oh, yeah. Yeah.

-Of the six targets scanned,

all of them registered
significant metal anomalies,

possibly from the sunken U-boats
the team is searching for.

Most promising of these readings
was a massive metal object

consistent with the size
of a submarine

detected near the site
dubbed target 2

on the U.S. naval chart,

located 5 miles
off the coast of Montecristi.

-We're gonna drop markers in.

This is where your skill set
comes in as captain.

Based on the weather
conditions today,

what do you think
our best option is?

-Today is already windy
and it's choppy

and the conditions
are gonna pick up.

-Yeah. Yeah.
-So I would go here...

-Okay.
-...which is tucked in.

-Right.
I agree with him.

Why don't we just
head there now?

-Absolutely.

[ Dramatic music plays ]

♪♪

[ Radar squealing ]

-To guide their search, Darrell
and the team drop a marker line

at the GPS coordinates
of target 2...

-Drop. Drop.

-...to give them
a starting point

for their search underwater.

-We're gonna follow
that marker line

that the buoy's attached to.

We'll follow that down.

If there's something 200 feet
of each side

of that marker, we'll see it.

-I like it.
It's time to go wet.

Time to go diving.

-Professional diver Steve Bender
has discovered

and salvaged shipwrecks
with Darrell for decades.

And while he and Darrell
are in the water,

Garth Baldwin will remain
topside, overseeing the dives.

An archeologist
and former Marine

who specializes
in World War II history,

Garth can help identify

whatever Darrell and Steve
bring to the surface.

Starting from their marker line,
Darrell and Steve will need

to carefully and manually
explore the ocean floor

to locate the metal anomaly,
which could be anywhere

within a 125,000-square-foot
search area.

-So, what are you guys
seeing down there?

It's a difficult environment
to try and find something

that is also potentially buried
under sand and turtlegrass.

One of the problems here is that

if there is
a U-boat on the bottom,

in all likelihood,
80 years of time and hurricanes

and saltwater
are gonna break this thing up

and they're gonna
distribute it out.

So you're looking for a part of
a needle in a larger haystack.

-Having swam nearly
200 feet north

with no sign
of the metal anomaly,

Darrell and Steve begin to swim
back to their marker line

to search in
the opposite direction.

-They moved from over here,

on the other side of the marker,
to over here.

Luckily, the marker's
been pretty stable.

Darrell, this is topside.

Can you describe
what you're seeing?

-After locating
a mysterious mound

that may be the anomaly
they are searching for,

Darrell uses a metal detector
to scan the area.

-Can you bring it up?

-Whoo-hoo-hoo-hoo-hoo!

-While diving off the northern
coast of the Dominican Republic

at the suspected site
of a sunken German U-boat,

Darrell Miklos and his team

discovered
their first possible clue.

According to blueprints
acquired by Darrell

and his dad in 1983,

the U-boats that were modified
to carry treasure

had a 37-millimeter gun

and an 88-millimeter cannon
on their decks.

If the object the team found
is ammunition

matching the cannons
on the blueprints,

it could suggest a treasure
U-boat might be nearby.

-Explosive rounds are set
to go off

after a certain number of turns.

Super dangerous.

-During World War II,

artillery shells were launched
out of rifled barrels,

causing them to rotate
at high speeds.

To prevent detonation
during the launch or close

to the launching site,

the shells contained
a firing pin

held in place
by detent springs.

The centrifugal force from
the rotations of the shell

would move the detent
springs outward,

freeing the firing pin
and arming the munition.

Darrell and Steve surface
with the possible munition,

eager to get
Garth's expert opinion.

-Bring it in.

-Can we lift it?
-Let me see.

It's got openings.
It's -- It's good.

That end is not --
That's not a munition.

I'm looking at the end.
It's not.

-Are you ready to take it?

-Yes, sir.

-Careful. It's fragile.
Especially that end.

-Oh, it's falling apart.

Yeah.
It's brass -- lots of brass.

Let's check it out.
Whoo!

My role on this is
to help identify

anything that Darrell
and Steve bring up...

-Look. They're so excited,
he left us behind.

-[ Laughs ] We're on our own.

-Oh, thanks for all
the help there.

-...to source its origin,

and if I don't know what it is,
I know people who do.

-So, this is not a munition?
-No.

It's got, like, a double skin
on it,

so it's got, like, a casing.

And there's something in there.

This is a casing,
and there's threads.

-Threads. Okay.
-I did see this come off.

-Oh, okay.
-And then we put it back on.

-Okay.
-So...

-Well, it came off once.

Oh, yeah.
There's the lens right there.

-Really?
-Yeah.

It's a telescope, bro.
Look at that.

-Look at that.
Very cool.

-The question more important
than anything,

is this World War II period?

Does this look like something
that could have been

off of a conning tower?

Is it Nazi?
Is it German?

-It looks earlier to me.

-Unfortunately for the team,

Garth believes the telescope
pre-dates World War II,

possibly dating back
as far as the 1800s,

and probably from
one of the many vessels

lost in the area's
notoriously dangerous waters.

-This is a great clue to what
was happening in these waters.

-Yeah.
The spyglass was a great find,

but we know that that's not
what set off the mag.

There's something bigger
down there,

and we need to find it.

Go diving.
-Do it.

-We searched the area
north of the marker,

so Steve and I
are now gonna go search

the area south of the marker.

-Having yet to locate
the metal anomaly

detected here in their earlier
magnetometer survey,

Darrell and Steve
continue their search

for what they hope
might be a U-boat,

either intact
or in large chunks of debris.

-I know that there's
a larger target.

It had to have been big enough
for a naval pilot

to identify it from the air
and then mark it on a chart.

-Steve, what's your visual?

Not a U-boat.

Massive hull.

That probably explains
the mag's signature

being as big as it was.

♪♪

-Judging by the growth
and the way it looks,

this boat could very well be
from World War II era.

-Upon close inspection,
the large shipwreck appears

to be a merchant vessel dating
to the Second World War.

Although it is not
what they're looking for,

this sunken ship could have
important clues

connected
to Nazi U-boat activity.

-The question is, why is it here
and how did it sink?

Something catastrophic
happened to that boat.

Whether it was blown up
or torpedoed, we don't know.

-After searching the sunken
hull, Darrell and Steve

are unable to see clear evidence

of what caused the ship
to sink...

...although their search
does raise a question --

was this merchant vessel sunk
as part of a battle

to control
vital shipping lanes here

during World War II?

Or could there be
a further connection

to the modified U-boats
Darrell is looking for?

-It's a cool ship,
but you want to know what?

It's not a sub.

And the positive --
the mag hits are working

because we were
right on target.

-Excellent.

-At least we all
know one thing --

we can check this guy
off the list.

And let's move on.

-Having eliminated target 2
as the site

of the modified U-boats
they seek,

the team decides to move
to the next closest anomaly --

just 4 miles northwest
at target 1.

♪♪

-Close.

-10 feet, 8, 4.

Good.
-Do it.

I want to see as many
of these targets as we can

before the hurricane season
forces us out of the water

for the rest of the year.

♪

-Starting from
their marker line,

Darrell and Steve once again

search the area
in a systematic grid.

Although the magnetometer
registered

a significant metal object
around target 1,

finding it takes a careful
examination of the seafloor.

What appears like a natural
turtlegrass or ocean formations

could be pieces of a submarine
camouflaged by the terrain.

-It's just a matter of trying
to locate it

within the 30 minutes-ish
that they have to be down there.

They're somewhere out
in that direction.

You can see that the wind
is kicking up the water.

Either of you guys hear me?

-With their oxygen tanks
nearing empty,

Darrell and Steve decide
to return topside.

However, wind gusts have
increased to 34 miles per hour,

causing ocean swells
of nearly 8 feet high

and making conditions
on the surface treacherous

for the returning divers.

-Watch your head.

-Off the waters of the Dominican
port city of Montecristi...

treasure hunter
Darrell Miklos

and his team battle
treacherous ocean conditions

at the location
known as target 1,

one of the possible sites
of a sunken Nazi U-boat

that Darrell believes was
hauling Nazi treasure.

-These swells are getting
pretty wicked.

-With dangerous swells
on the ocean's surface,

Darrell and fellow diver
Steve Bender must be careful

as they board the 47-ton boat,

which could slam down
on them at any second.

-Hey!
Watch your head.

That was close, bro.

Hang on.
These [bleep] swells.

-Watch out.
-[Bleep]

-I got you.

-That boat's moving, man.

-[Bleep]
-Want a rope?

♪

-You good, Steve?

I was able to get on the boat
barely.

And Steve comes in,

and the entire boat
almost landed on his head.

It literally came that close.

-If it was easy...

-Everybody would do it.
-...everybody would do it.

-It's really frustrating
that there's so much wind

this early in the season.

There's something there,

but we're not gonna be able
to dive that today.

♪

-Unfortunately for Darrell
and his team,

the severe weather means
further diving at target 1

is out of the question
for now --

a harsh reminder that hurricane
season is fast approaching.

The next day, with rough weather
conditions persisting at sea,

Darrell and his team meet at
their base camp in Montecristi

to strategize how to continue
their investigation on land.

-So, we hit target 2.

We know that this wasn't a sub.
But I'll tell you what.

I'm excited that we were able
to locate this.

We dove on it.
It was fantastic.

It matched up with what
we got here on the chart.

So that's a good sign.

-How cool was the bow
of that boat, though?

-[ Laughs ] It was pretty
amazing, wasn't it?

-Yeah.

-Judging by the growth
and the way it looks,

this boat could very well be,
in my opinion,

from World War II era.

But it's not a U-boat,
so we're moving on.

It just lets me know -- Again,

I'm super excited about the fact
that it was on the chart.

So, each one of these targets
is something important,

possibly a U-boat.
That's what we're here for.

We should be able to find each
and every one of these targets.

-I was so surprised how quickly
that weather

changed on us out there, though.

It was like beautiful, flat,
calm seas this morning and --

boom -- all of a sudden,
those winds picked up.

We were talking to Paco.

He was saying for the next
seven days, wind's blowing,

picking up in the afternoons
to the point

where we will
not be able to dive.

-I hope he's wrong.
I hope the forecasts are wrong.

But if we're working
against time,

the only thing we can do
is speed up our process,

diving earlier
and faster and more efficiently.

We can't let this weather
slow us down.

There's plenty of things
that we can do here in town.

-So, since we're off the water,

I'm gonna meet with a guy
here, uh,

Eric Roorda,
who's a historian.

He wrote a pretty extensive
history

on the Dominican Republic
that covers

the World War II period
and before.

You know, maybe he'll shed
some light on this for us.

-For Darrell and his team,

Montecristi serves as more than
just a base camp,

it's the port nearest
to their dive targets.

The area is also a major focus
in their investigation

because of its strategic
location on the northeast coast

of the Dominican Republic.

This not only made it
a vital area for U-boats

to hunt merchant ships
during World War II,

but could also explain
why modified submarines

might have been transporting
treasure through this area.

-Why don't you and I
do what my dad used to do?

He used to go into town,
get in touch with the locals,

have a conversation, see what
information we could gather.

You know, it's like boots
on the ground.

-I love it. Let's go.
-Alright.

♪

-As Darrell and Steve head out
to interview locals...

-Let's pull up
right behind that.

That looks like a good area.

-...Garth meets with historian
Eric Roorda...

-Eric, I really appreciate...
-...an author

who has written extensively
on the history of the Caribbean.

-We're down here,
looking for German U-boats.

We have seven targets on this --
on this chart that was made,

and they are potentially
U-boat associated.

And so why are German U-boats

clustered so close
to Montecristi?

-A couple different reasons.

Uh, the Dominican Republic
is very strategically located

in terms of the shipping lanes
through the Caribbean.

There's only a couple of ways
to get from north

to south in the Caribbean.

You can either go between
the island of Haiti

and the Dominican Republic,
share Hispaniola and Cuba.

That's the Windward Passage.
-Mm-hmm.

-Or you can go between the D.R.
and Puerto Rico.

That's the Mona Passage.

So, if the Nazis were there
to destroy shipping,

then that would be
a good place to be.

Now, if they were looking
for a refuge,

they were hoping that they would
find some collaborators

among the rather large
German community

in the Dominican Republic --
the so-called German colony.

-German colony?
-Yes.

They'd been there
since the late 19th century.

Really important economically
for the tobacco trade.

-[ Chuckles ]
-And they were hugely important

to the Dominican economy.

-In the late 1800s,
Germans were dominant players

in the export of tobacco

from the northern coast
of the Dominican Republic.

22 million kilos
of Dominican tobacco

were exported to Germany,

much of it from the port
of Montecristi.

This supported a good-sized
German population in the town.

-On the eve of World War II,

there were about 300 people
of German descent

in the Dominican Republic
and another 150

who had actually
been born in Germany.

-Wow.

-And there were plenty
of sympathizers to go around.

-Really? So there were members
of the Nazi party

that were living
in the Dominican Republic?

-Yeah,
especially in Montecristi.

In fact, there was
a Dominican Nazi party.

♪

-During a meeting with
historian Eric Roorda

at the team's Montecristi
base camp,

Garth learns something
surprising.

-I didn't know that there was
a Nazi party

that existed
on the Dominican Republic.

-There was a Dominican
Nazi party, yeah.

-Golly.

-Records obtained

through the Nazi War Crimes
Disclosure Act of 2007

tell of spies living
among the locals of Montecristi,

as well as a 50-member
Nazi party

based throughout the country.

Is it possible these Nazi
operatives are connected

to the U-boats
the team is searching for?

And if so,
what were their plans?

-That then sets up
a possibility...

-Mm-hmm.
-...that U-boats were able

to come here to seek assistance.

-Right.

-The Germans in the U-boats

would have been able
to contact those people,

speak the same language, blend.

German sailors did it
in other parts of the world --

undercover, snuck into places

where there wasn't
a huge German population.

In Nova Scotia, there was
a U-boat off the coast,

and it was hiding.

When we took that boat, there
were movie tickets from town.

There were bread wrappers
from the grocery store.

They were shopping at the store,
they were going to movies,

and nobody ever knew.

-There were articles
in the U.S. press

that supported
that the Dominicans

on the North Coast

were collaborating
with those Nazi subs.

You may be familiar with
"The New York Times" report

from 1939 of a -- of
a Dominican Coast Guard vessel.

And so, it says,
"Coast Guard craft said to have

sunk after collision
with French destroyer."

-We read in the old newspaper
from the '30s

that there were German U-boats

being refueled off
the Dominican north coast.

It all makes a lot more sense
now why the German U-boats

were coming here.

-With a small sympathetic
German population

and the ability to refuel
just off the coast,

could Montecristi
have been a hub

for Nazi U-boats during the war?

And is that the reason there are
seven possible U-boats

marked on Darrell's chart?

As Garth concludes his meeting
with Eric Roorda,

across town, Darrell and Steve

are investigating a tip
they received

about a local dive-shop owner

who knows of a shipwreck
near Montecristi.

They hope it might be connected
to the U-boats

they are searching for.

-I'm meeting
with a dive-shop owner.

His name is Robinson.
He's a local guy here.

He dives out here all the time.

[ Speaking Spanish ]

Ahh!

His family's been doing it
since the '80s.

They've been treasure hunters
since the '80s.

-Wow.
-[ Speaking Spanish ]

He said there's one right here.
-[ Chuckles ] Really?

-And he's seen a lot of --
-Oh, when he's here.

-Yeah, he's seen a lot
of metal wreckage,

but he's not interested
in that, obvious.

He's interested in treasure.

-Neither were we until now.
-Yes.

-Ask him if he's comfortable
with us diving from here.

-[ Speaking Spanish ]

Okay.
-Wow.

-Wow. Okay.
-Okay.

-This is really a lucky
break for us.

If this wreck turns out to be
from the World War II era,

it could lead
to further information

about U-boats in this area.

-Vamanos.

You want to hit it?
Can we get up some speed, guys?

-As a new day begins
in Montecristi,

Darrell Miklos and fellow diver
Steve Bender

are following up on a tip
of a possible

World War II-era shipwreck
located near shore.

-Follow that buoy line down.
Right here.

-While rough seas prevent
diving the targets

on their chart
or returning to target 1,

he's using his time to look for
any clues that might fine tune

their search for the location
of modified U-boats.

To assist in their
investigation,

Darrell uses a metal detector

to search for artifacts
among the wreckage.

[ Metal detector squealing ]

[ Metal detector squealing ]

-This debris trail is telling me

that whatever happened
to this ship --

something violent and terrible.

-Darrell and Steve
quickly determine

that the wreck is most probably

another World War II-era
merchant ship.

Although it's not
the U-boat they hoped for,

the debris trail could still
contain important clues.

Finding evidence of an explosion

is a potentially important
development.

According to the blueprints
of the modified U-boats,

the vessels had to rely
solely on deck cannons

for defense because
the standard torpedoes

were removed to make room
to store gold and riches.

If the team can find evidence
matching these cannons

to the burned wreckage,

it could support Darrell's
belief that the Germans

were transporting treasure
in this area.

-I'm hoping to figure out
what brought this ship down

and if there's any evidence
of a U-boat.

So far, I'm seeing burnt wood,
fused metal,

and that's very consistent
with an explosion.

-We pulled up a lot of evidence
of boat material

from this current site,

and I want to bring
this to Garth

and help us put the pieces
of the puzzle together.

What I want to find out is,
was this a merchant ship?

How was it sunk?

Was it sunk by a U-boat?

I need his expert,
professional opinion

to help put this story together.

Alright.

So, when Steve and I made
our approach,

this is what we first saw.

You see a lot of turtlegrass,

and then it drops
into the sand pit.

And -- ta-da! -- there it is.

-Is it sunk into this, like
a topographic, like a contour?

-Yeah.
That's right.

-Was there any sort of cable
or anything?

-We've got three spools.

You can only see two.

-That right there looks
like a drive belt.

So, that this is a drum
where you'd have a belt on it

that would turn this,

and then this would turn,
in turn, the other gears, right?

-Kind of like gears on a bike.
-Yeah, yeah, yeah.

Whatever it is,
it's massive, right?

-Yeah.
-And it's like --

It's got to be for lifting
something incredibly large.

And this is definitely something
for moving cargo

on and off ship.

The shipwreck that
they've identified,

it's pretty obviously
a merchant vessel

or something that's
moving materials.

But out here in these waters,
with the level of swells,

anything can take a boat down.

I mean, a debris field --
it could be offshore currents

that are driving
these things out.

They could have just hit
the rocks,

and it rotted out there
and then got pulled apart.

-So we -- we did pull up
a couple items,

so why don't we just
show them to you,

and let us know what you think?
-Cool.

This is pretty cool.

-There's that.

Chain.
There's that.

-This.
What is that?

-So we did pull up
a couple items,

so why don't we just
show them to you,

and let us know what you think?
-Cool.

-After investigating the
wreckage of a merchant ship

which sank just off
the coast of Montecristi,

treasure hunter Darrell Miklos
is eager to share the evidence

with team archeologist
Garth Baldwin.

-What is that?

I mean, that's wormy wood.
-Yeah.

-I thought that was part
of the deck.

And it looks burned, too.

Yeah, yeah.

We found wood down there
that had burn marks all over it.

You could tell this thing
caught fire.

We know that it caught fire,

but there's got to be
more to the story.

Was it sunk?

And if so, was it sunk
by a U-boat?

-This is burned.
It's light, though.

-It looks like it could have
been part of a metal object

that was under extreme heat,

almost to the point
of molten-hot.

-Slag. It's called slag.
-And -- yeah. Slag.

-See how it has
that porosity in it?

-Yeah.
-Those holes in it?

This is the result of metal
being burnt

at a high temperature.

-Yeah.
-Weird.

This is weird. This is a --

It's like a twisted,
bent metal...

-That's impact.
-...strap or something.

-That's impact.
-Yeah. And that's a big bend.

You know what I mean?
Like, it was an impact.

Like, it hit a rock
or something like that.

-Right.
-Except there were no rocks.

-No rocks anywhere,
even on our approach.

-Yeah. It's just mush.

-It's turtlegrass and sand.

-Yeah.

Well, something exterior came
and hit it, probably, right?

-Right.

-We have a merchant vessel that
was impacted catastrophically,

went down by intense fire.

You know, this is
pretty consistent.

This is one of those things
we should expect

to see from a merchant ship

downed by a torpedo
from a U-boat.

-During World War II,
German U-boats

were generally
armed with torpedoes,

carrying 660 pounds
of deadly explosives,

capable of easily piercing
a ship's hull

and setting it ablaze.

Since this vessel
was destroyed by a torpedo,

it eliminates a modified U-boat
as the cause.

But the damaged ship
could raise further questions.

-We've now found two sunken
merchant vessels in Montecristi,

and I'm starting to wonder
if there's a pattern here.

Thanks to Garth,
we know that there was

an actual Nazi party
here in Montecristi

and that the U-boats
may have been refueling here.

So I'm asking myself --
did these merchant ships

see something that
they weren't supposed to?

Were they in the wrong place
at the wrong time?

-Could Darrell's theory
be correct?

Is it possible that two
merchant vessels

were sunk to cover up
Nazi activity in Montecristi?

And if so, what was
that activity?

-We came here
with seven targets,

and even though we haven't found
a U-boat yet,

all the signs are pointing
to something going on here.

I believe that it's
no coincidence

that we're finding
merchant wrecks here

in the same place
that we have this chart

with seven U-boats
marked on it.

Now, for the first time
since me and my dad

started searching
for this treasure,

I feel like
we're on to something.

-This is where
they were hunting.

-This is it.

-For Darrell and his team,
six targets now remain.

Any one of them could be
a hidden U-boat

containing millions
in stolen treasure

and, along with it,
priceless answers

to one of World War II's
biggest mysteries.

This season on "The Lost U-boats
of WWII"...

-I'm a treasure hunter by trade,

but from this point on,
I'm a U-boat hunter.

And I'm gonna find me one.

Why the hell are German U-boats
coming to Montecristi?

Time to go diving.

We are going to gather clues
each time we dive.

-Whoo-hoo-hoo-hoo-hoo!
-Wow.

-Why exactly were those
U-boats here?

-You saw the swastika.

-What secrets do they hold?

This was on a U-boat.

There's so many secrets
that are being held

right here
in this sleepy, little village.

-[ Speaking Spanish ]

-[ Speaking indistinctly ]
[Bleep]

[ Cannon fires ]
-What about that?!

That's German.

Our vision of the Nazis
was all happening in Europe.

-[ Speaks German ]
-Nobody realized just how close

it was to our country.

[ Torpedo fires ]

What is that?!

Are we still looking
for treasure

or something far more sinister?

Oh, my God!
