The transatlantic slave trade existed for well over 300 years and involved more than 45,000 voyages.

Most ships made it.

Many didn't.

In the early 1800s, even after most countries banned the trade, illegal trafficking was continuing.

My ancestors could have easily ended up on the illegal Spanish slaver, "The Guerrero."

♪ COREY: "The Guerrero" was sailing to Cuba with almost 600 African people on board.

They sailed past the Bahamas.

Stationed there was a British navy ship, "The Nimble."

"The Nimble" was there to intercept illegal slave ships.

They tried to stop "Guerrero".

"Guerrero" took off.

They got into a chase, they got into a gun battle.

Eventually, night fell.

Both ships slammed into the Florida reef somewhere off Key Largo.

So beneath these waters now are the puzzle pieces that are gonna help us reconstruct the story of these two shipwrecks.

How are you?

You guys ready to do a little bit of research?

We are!

JOSH: So what is this story about "The Guerrero" and why do you think it's "The Guerrero"?

You know, the story of "Guerrero" is really the story of two ships: "Guerrero", the slave ship, and then the British navy schooner that was chasing it.

And they got into a gun battle and they both smashed into the reef.

♪ "The Nimble" ran aground and was able to float itself off the reef by jettisoning iron ballasts and cannonballs.

But the slave ship "Guerrero" crashed into the reef with such force that it sank.

41 of the captive Africans on board died.

"The Nimble's" crew said they could hear the screams crossing two miles of ocean.

It had been their duty to save the people on "The Guerrero", but instead they had accidentally chased them to their doom.

We're going to find "The Guerrero".

There could be all kinds of artifacts out there that are specific to a slave ship.

So here I have some things to show you guys.

(all) Oh!

These are all pieces recovered from other wrecks.

So what's this guy?

A tooth extractor.

I remember in school, we were taught some slaves wouldn't eat in protest.

They would remove the teeth so that they could shove food... - Right.

- ...in their mouth.

Just visualizing that is absolutely chilling.

That my ancestor could've had their teeth pulled to make them eat because they needed to be strong in order to be bought.

[gag reflex sound] And here is the real telltale artifact.

The essence of the slave trade: a set of shackles.

These were the iron restraints designed to hold people two by two.

Wrists?

Wrists and generally ankles.

You slid this 'U' onto somebody's ankle.

You took this other 'U', put it on another person's ankle, and then those people were joined together.

It was shackled to two people cause it makes it way more effective to keep people from running.

Right.

If you're, you know, hobbled to somebody else, you can't swim.

You can't run.

- Right.

- You can't move.

Your coming back, having identified yourself as a Benga, through DNA, was something that was a shock to the Benga community because of all the millions of Africans that left Africa, to have a person in America be identified as Benga was phenomenal.

So to be integrated into Benga society, you need to acquire certain materials.

Senior diver, Kramer Wimberley joins the team.

Now you get to come play with us!

Yes.

I missed you guys.

Corey fills us in on his plan... I think really in order to find "The Guerrero", we're going to have to find evidence of "The Nimble".

"Nimble" essentially left a trail.

♪ "Nimble" had run up onto the reef.

They needed to lighten their load.

They were able to free themselves by throwing over iron ballast blocks and cannonballs.

They got anchored up, and then their anchor line parted.

They drifted onto the reef again and they threw over more cannonballs, ballasts, more shot, and a small cannon.

♪ So we're looking for things that the Nimble threw off Exactly.

Those are our clues.

So the biggest clue we have in the historical record in all of this is the position of "The Nimble" the morning after the ships hit the reef.

"The Nimble" was towed to safety off the reef, and the captain took his bearings.

And we know where that spot was.

That was right here.

So we know that "The Nimble" was anchored here after, but we don't actually know where it hit the reef, right?

Right.

Exactly.

So what we have to do is account for things like the wind and the weather at that time and which direction the ships were sailing when they hit.

When you take in all the historical evidence, it makes it pretty clear that those two ships hit at either here at Area "A", Area "B" or Area "C".

If we can find evidence of "The Nimble" in these areas, I think that's gonna help us pinpoint the location of "The Guerrero", and of the captive Africans who perished there.

Today these areas are separated.

You have the park and the sanctuary.

Yeah, Kramer, if you want to go up to Area "A", the northernmost spot.

Up in Biscayne National Park and do some exploring with the folks from the Biscayne team, and the rest of us, we'll go down to Areas "B" and "C" and take a look around and see what's there.

Most importantly, sadly, African men, women and children.

We don't bring tourists this way... not much.

This is Ntchorongove Village.

Yup, I used to be barefoot on roads like this.

Where?

Isn't that an elephant in there, right there?

- Yeah, that... - Amazing.

It looks like it's on its own.

It's probably a lone male.

[elephant trumpeting] So in terms of the amount of ivory being transported on this river, what was the number of elephants lost at that time?

Probably hundreds of thousands of elephants.

The whole coastal Gabon and Congo was basically devoid of elephants by the time they finished.

By the time they finished.

And they severely depleted the human population as well.

They were just another commodity.

Moved down these rivers all the way to the coast where they would be sold off.

Shackled and shipped.

Yeah.

There were hundreds of slave boats coming down here.

[speaks French] And so, literally, there are millions of oysters, and they've built up the level of these islands 4 metres.

So what just looks like earth, is actually millions and millions of oyster shells piled upon each other.

That was the only food that the captive peoples had to eat when they were here.

That's right, your last meal before you get on a boat to be sailed off to Brazil.

So that really is an oyster bank.

They're razor-sharp.

Until Richard came, nobody thought that's a relic of the slave trade.

And then you start to think about how many people... it's acres worth.

That's two and a half thousand acres.

Two and a half thousand acres?

Okay that's a--that's ridiculous.

- Of--Of oysters.

- Of oysters, like that?

So right out there?

They█d likely see the ships offshore For those who were taken from the interior, it would've been the first time they'd ever seen the ocean.

Now right here you see a very fine taper.

This is called the nozzle, and it's particularly dateable.

They didn't have these on most carronades before 1815.

- It's, like, way-- And if it's underwater, it probably was brought in on a ship, and that's what we're seeing here-- rocks that just don't fit the natural landscape.

♪ Corey's location mapping might just be on the money.

I can see something.

(filtered voice) This looks like an iron knee or some sort of a brace.

It looks like it's from the right time period.

Iron braces like this could've been used to reinforce the hull structure of ships like "Guerrero".

Oh, the brace you were talking about.

Triangular brace.

Certainly it was part of the ship.

It was used to, you know, reinforce something.

As I move it around, you know, you get a really good sense of the shape of it nestled in a little pocket in the hard bottom.

(filtered voice) And next to that, another piece of iron-- a pin that held some of the ship together.

♪ It's becoming more and more evident that we're over a debris field.

♪ And then, there it is.

Our smoking gun.

[filtered voice] This oddly shaped piece of iron with these two flat heads-- it's a bar shot.

The Spanish use?

- Looks to be Spanish, you know.

- Right.

And fits the time, fits the nationality for "Guerrero", and here it is.

This is exactly what we'd expect to find on a Spanish ship like "The Guerrero".

♪ The evidence is there.

It seems like a wreck definitely was in this area.

It's beautiful and sad altogether, like, to be down there amongst that stuff, amongst the wreckage.

♪ I feel absolutely confident that we have found the wreck of "The Guerrero".

[faint screaming] This is a gravesite.

Anyone who dives a wreck like this has to understand that there's history and people's stories and people's lives and people's deaths associated with that.

[screaming] So it's a "sombering" kind of experience.

It's giving voice to people who don't have a voice anymore, and that's what this entire experience has been all about.

♪ I'm humbled.

♪ Centuries after my ancestors were sold into slavery, I've reunited with their tribe.

I count this as a victory... not just mine, but for all those that never made it back.

[Benga people chanting] From day one, the Benga have welcomed me with open arms, but today they're making it official.

[chanting continues] In a traditional initiation ceremony that is centuries old, the tribal elders are reintegrating me into Benga society.

[chanting continues] [metal instrument clanging rapidly] I was a lost son that returned, and I wanted to connect with them, and they could feel that I wanted that.

[chanting continues] It's like I put a link back in my chain that was broken.

I repaired it.

[chanting continues] I am part of this.

This is where I came from.

This is my beginning.

[Benga people chanting] Given that we already share Benga DNA, it kind of makes sense when the clan leaders tell me that blowing air into my hands symbolizes the "breath of life" that animates my new Benga body.

[chanting continues] These are some powerful blessings.

[speaks in native language] Blessings.

[metal intrument clinging] [translates] [speaks in native language] [people chanting, metal intrument clanging] And this is where the sacred, ritual items that I collected earlier come into play.

[speaks in native language] [indistinct chatter in native language] [laughs] [speaks in native language] [Benga people chanting] [chanting continues] [Benga women ululating] [sing in native language] [Benga people chanting] [speaks in native language] [crowd cheering] ♪ I wish I knew how ♪ It would feel to be free ♪ I wish I could break all the chains holding me ♪ ♪ I wish I could say all the things that I should say ♪ ♪ Say 'em loud, say 'em clear ♪ For the whole round world to hear ♪
