- What's up, Dave?
- Hey, boys.

How you doing?

- So what did you guys find
that was unique on this dive?

- Let's start with showing you
the measurements

of the prop here.

- Looks pretty large in size.

- Yeah, exactly.

I mean, this actually speaks
to the era as well,

'cause this is
a very primitive propeller.

We were able to ascertain
this is an old steamer,

very archaic,
definitely 19th century,

probably Civil War era.

narrator: Propellers,
also called screws,

had only been in use
for about 30 years

at the time of the Civil War.

By 1864,
propeller-driven steamers

were quickly replacing
paddle steamers

that struggled in rough seas.

Early steam ships
also had sails in case

the engines broke down.

- You have any idea of what
may have brought the ship down?

- We have found
multiple fragments of china

on the bottom...
- Really?

- As well as molten brass

that is melted
and now hardened.

And we have, actually,
a piece of this brass with us.

- [groans]
- Check that out.

- So this is
basically something

that was destroyed
by way of fire.

- It just melted,
'cause obviously,

brass has a lower melting point

than, say, like, steel or iron.
- Yeah.

- And as it melts,
it just turns molten.

And it hits that cold water
and obviously

freezes it into whatever shape.

And all that china as well,
hits that cold water,

it just shatters.

narrator:
Passengers returning home

likely brought china
on the D. H. "Mount,"

but the ship disappeared
without a trace.

It might have suffered a fire,
but there's no way to be sure.

On the other hand,
survivors of the "Leo"

reported their ship
was on fire

when it went down
in a storm in 1877.

Jason points to one
obvious cause of fire

on ships in the 19th century.

- Lightning has always been
a factor of safety at sea,

especially in the 1860s
and 1870s

when ships didn't have

lightning protection
mechanisms.

narrator: Contemporary
British Navy records document

235 lightning strikes
that resulted in

40 ships damaged

were not yet found on
American commercial vessels.

♪ ♪

Mike has a theory based
on another common threat

to early steamships.

- These boilers had
a tendency to blow up.

At one point over 20%
of steamboat losses

were due to boiler explosions.

- Oh, wow.

- Well, exploding boilers
and fires on board steamships

are not really my expertise,

but I do know
the person to speak to.

narrator:
To ID the prop wreck

and determine
if it's either the "Leo"

or the D. H. "Mount,"
the team will need

more evidence from the bottom

on what could have caused

a fire hot enough
to melt brass.

next time we meet,

we'll have more
information for you

narrator: David's first stop
is Chicago,

home to an authority
on nautical history

named Gene Salecker.

- Gene is an expert
on these ships,

and in particular
how the boilers tick.

So what I want to do is I want
to basically pick his brain

to see if there
is a possibility

that the boiler may have been
the issue for these ships.

♪ ♪

- Boiler explosions were
just waiting to happen.

It wasn't a matter of if.
It was a matter of when.

narrator:
In early steamships,

stokers shovel coal
into a furnace

that sends heat upward
to a large steel tank

of water called the boiler.

From there, steam rises
into metal drums and moves

the pistons of the engine
that turns the propeller.

But steam pressure
was a constant hazard.

The engineer had to carefully
monitor the pressure gauges

or risk a catastrophic
explosion.

- So if that's the case,
to be able to figure out

exactly what happened,
what are some

of the indicators
they should be looking for?

- Well, if they have found
the boiler

that they can look into,

they can see, is there
a portion of that boiler

that is blown away?

narrator:
But according to Gene,

not all boiler explosions
were accidental.

- Perhaps if it's from
the lower bottom front of it,

that could be
possible sabotage.

- Oh, really?

- Oh, yeah, yeah.

narrator:
Sabotage is a possibility

the team never expected.

One method was to toss an
explosive into the firebox

under the boiler.

- So, I mean,
how common was sabotage

towards the end
of the Civil War?

- It was actually
fairly common.

We've determined that there's
been about 35 steamboats that

were destroyed by
Confederate boat burners,

as they called them.

- 35, wow.

I mean,
that's quite significant.

Steamships in the 1860s
were essentially

floating tinderboxes.

You've got a boiler,
you've got coal,

you have kerosene lamps
that are all over the ship,

above and below decks.

I mean, under
the best of circumstances,

it is a ticking time bomb.

But you add bad seas
and perhaps even

the specter of sabotage,
and boy, you have

the specter of sabotage,
and boy, you have

a tragedy waiting to happen.

narrator: Why would someone
want to sabotage either ship?

It turns out a passenger
on one of the ships

was a tempting target.

♪ ♪

Jason Harris is following up
on this clue.

Jason meets with Civil War
historian Dr. Seth Weitz

to learn more about
who was on the D. H. "Mount"

when it went missing.

Could someone
have intentionally

sunk the D. H. "Mount" to take
out these Union sympathizers?

- One of the theories is
that the D. H. "Mount,"

and more specifically
the passengers,

that they would have been
targets of sabotage.

- On board were at least
20 or so Unionists,

and one of them was
a prominent

Jacksonville citizen,
Judge Samuel Burritt.

They're headed
ultimately to Tallahassee

for a new constitutional
convention

that's supposed to restore
Florida to the Union.

narrator:
This convention was to enact

a new constitution for Florida

of precedence for sabotage

or any type
of nefarious activities

during this time period?

- There were a lot
of conspiracies, plots

that were kind of hatched
by the Confederates

before and possibly
after the Civil War.

- Tell me about the kind
of things that they

would use for sabotaging.

- Towards the beginning

close it back up,

and the hope was that whoever
was dealing with it would just

shovel it into the furnace,

narrator: Mike's uncovered

It's a pressure gauge.

a deep pressure gauge.

You see the glass here there's
going to be under here,

it's kind of pushed in.

But with a little bit
of cleaning,

we might actually find
a manufacturer's information,

maybe a date or a serial number
that we can trace

back to the actual vessel.

back to the actual vessel.

narrator: This gauge
measures the pressure

on a steam engine boiler.

And it may be
the smoking gun clue

the team has been looking for.

narrator: Mike Barnette
and Jimmy Gadomski

have just completed another
dive on the prop wreck.

They found a gauge that
could be the final clue

to solve the mystery.

Is the wreck the "Leo,"
or is it the D. H. "Mount"?

To know the answer,
Mike takes the gauge

to be professionally restored.

- This artifact
potentially has some very

important information that can
help us identify this wreck.

So we're going to talk
to an expert

and see if he can reveal
a little more information

for us on this gauge.

Nice to meet you.

for you to look at.

narrator: Mike is hoping
this gauge will

finally reveal
whether he's found

the D. H. "Mount"
or the "Leo."

- What kind of
important information

would a gauge how that
would potentially help us

identify a shipwreck?

- Well, if you find
serial numbers,

you can try to reference
the date

- Well, let me show you
our steam gauge.

I'll show you, first, what it
looked like when we found it

on the bottom of the wreck.

So this is when
we originally found it.

picked it up, that...

Oh, wow.

- Yeah.

This is where
I got through the glass

some engraving down here.

It's really...

information in hand,

Mike meets up with Jason
Harris and Jimmy Gadomski.

- What's going on, fellas?
How y'all doing?

- Hey.
- What's happening?

- Good to see you guys.

It looks like you got
some pretty cool stuff here.

Tell me a little bit about what
happened on that last dive.

- So we got back in the water.
We got an amazing artifact.

So we found a pressure gauge
just right

near the boiler and engine.

- Now it's cleaned up
and you can

decipher a lot of information.

I took this
to a steam engine expert,

and he determined this was
most likely built 1864.

narrator: That date makes
a strong case

for one of the two
missing ships.

- This came off the "Leo."
- Yeah.

That, I think, it makes sense
because based on your numbers,

so we know the D. H. "Mount"
was built in 1863

and the "Leo," which was built
two years later in 1865.

This number seems like
it corresponds more to "Leo"

than the D. H. "Mount."

Would you agree with that?
- Definitely, yeah.

This came off the "Leo."

narrator:
The gauge was made in 1864,

a year after
the D. H. "Mount" went to sea.

But the team's other suspect,
the "Leo," launched in 1865.

It's a perfect match.

This artifact had
to come off the "Leo."

One big question remains:

what caused
that mysterious fire

that sank the "Leo"?

Jason Harris has new answers.

- You know, doing
a little bit of digging,

there were some things
that jumped out with regards

to the "Leo" in particular.

It had some really
interesting cargo.

They were carrying
a case of china,

was one of
the particular pieces

of information we learned.

♪ ♪

And they were carrying roughly
about 130-plus gallons of gin.

narrator: Jason's found
eyewitness accounts

saying crewmen were
securing loose cargo

when their lantern
ignited fumes

from a broken cask of gin.

It was alcohol that
triggered the blaze,

not a boiler explosion
or lightning.

And adding all the clues
together,

the size of the propeller,
the brick, the melted brass,

broken china,
and most importantly,

the date of the gauge,
the team can

finally identify this wreck.

a really, really strong case.

I mean, this is
almost insurmountable,

the amount of information
