♪♪ -USS Indianapolis -- a proud warship with a distinguished battle record.

-It was the quarterback of the Fifth Fleet.

-They called it the Indy, and it played a crucial role in the climactic events of World War II.

-And they tell him, "Every day we cut off transporting this package is a day that's cut off the war."

-In 1945, Indy's legacy would turn tragic when enemy torpedoes sent it to the bottom and 900 survivors drifted for days in shark-infested waters... -You could hear the shipmates screaming for help, and you really couldn't tell where the screaming was coming from.

-...while the Navy lost track of them.

-We didn't show.

No one's looking for us.

-This is a story about young men at their best and the sea at its worst.

-Now a team of undersea explorers uses advanced technology to search for the ship.

-We need to talk about the best probable position for the sinking.

Where is that spot?

-Indianapolis is no longer lost at sea.

-Yep.

That's it.

-Yeah!

[ Applause ] -Extraordinary images reveal Indianapolis as they found it 3 1/2 miles down.

-Beautiful.

-For those who served and suffered, it's a chance to heal old wounds... -This is hallowed ground for them.

-I want to keep the story alive.

♪♪ ♪♪ -November 1968.

Charles Butler McVay III is tortured by memories of his lost ship and his lost crewmen.

-"Dear Captain McVay..." -"I hope you're having a merry Christmas.

We would be, too, if you hadn't killed my son."

-"My son would be alive today."

-"Yours truly..." -After 23 years, their families still blame him, and he blames himself.

He was a respected commander with a spotless record, his ship one of the Navy's finest.

All that changed within minutes as the fortunes of ship, captain, and crew took a tragic turn.

The sinking of USS Indianapolis would be remembered as one of the darkest episodes of the war.

♪♪ ♪♪ Decades after Indianapolis disappeared, the crew of another ship is determined to find its remains and finally put to rest the painful memories of its loss.

They're aboard the research vessel Petrel.

Built to support oil and gas exploration, Petrel was purchased in 2016 by philanthropist Paul Allen and refitted to search for lost shipwrecks.

The expedition director is Rob Kraft.

-Petrel and her capabilities are dedicated solely to searching in very deep water and looking for very specific large targets, archaeological sites.

-But this particular target presents tremendous challenges.

Others have searched for Indianapolis and failed.

It sank in some of the deepest waters on the planet, and no one knows exactly where.

♪♪ Indianapolis may be an elusive target, but it's also a big one.

The ship was 600 feet long, the length of two football fields.

Commissioned in 1932, the Indy was one of a new class of heavy cruisers, fast, sleek, and bristling with armament.

It was designed as a floating gun platform with three mounts of giant 8-inch guns that could hurl projectiles up to 17 miles.

For defense, it was armed with more than 40 antiaircraft guns.

[ Gunfire ] A trio of floatplanes equipped with pontoons served as scouts and long-range spotters.

♪♪ -When they built the heavy cruisers, they had two missions in mind.

First one was those big guns, but the second mission was, they were built as command and control ships, so they had large flag officer quarters, admiral's quarters on board.

Before the war, it was actually President Roosevelt who used it as his ship of state.

During World War II, it became Admiral Spruance's flagship for the Fifth Fleet.

-Bill Toti was the captain of another USS Indianapolis, a nuclear submarine.

He feels a special connection to the original Indy, and he's proud of its record in war.

-It responded immediately as part of the task force that went out looking for the Japanese fleet that had attacked Pearl Harbor.

-The reputation of the Indianapolis within the Navy was impeccable.

It was, if you will, the quarterback of the Fifth Fleet.

It was a real place of pride in the Navy.

-It's a very storied history that is unfortunately overshadowed by, you know, the worst 12 minutes of her service.

♪♪ -I was in the Marine Corps, and after boot camp in San Diego, they sent me up to San Francisco, and there was the big USS Indianapolis, you know, and you could imagine what a country boy thought when he saw that.

200 yards long, you know, and that was to be my home for the duration of the war.

-I couldn't believe the size of her.

I've seen a lot of boats in my time but nothing with all the armaments she had.

It was an experience for me, being born back in the woods of Michigan and coming out to all this activity.

It was really, really something.

-Indy and its crew fought their way across the Pacific, earning 10 battle stars.

-Tarawa, then the Marshalls, the Marianas, the Gilberts, Saipan... -Sea battle, the Philippine Seas... -...Tinian, Guam.

-...Peleliu.

-In late 1944, a new captain took Indy's helm.

This was his first major command, but he seemed born to lead.

-Charles Butler McVay came from a long line of naval officers and was a captain on the rise.

-Third-generation Navy, second-generation Annapolis.

Father was an admiral.

It was fully expected that Charles Butler McVay III would be an admiral like dear old dad.

-Captain McVay, he was a little strict, but he was one great captain.

-Captain McVay led Indy in the first naval attack on the Japanese Home Islands and supported the Marine landing on Iwo Jima.

The Battle of Okinawa would be a turning point for American forces and for Indianapolis.

-At this point in the war, the Imperial Japanese Navy was relying on teenage boys to fly their airplanes.

There wasn't enough time to train these teenage boys on how to drop bombs, so what they trained them to do instead was fly their airplanes into ships.

Okinawa is where that really started to explode, and so the struggle there was, "Can you shoot down that airplane before it impacts with you?"

♪♪ -Indy's gunners managed to stop half a dozen enemy aircraft, but one made it through, crashing on the main deck.

Its bomb penetrated the ship's armored deck plating and kept going.

-Put a big gaping hole all the way through the ship -- I mean, through the mess hall, through the berthing compartment, through the water-distilling plant, and then it went through the bottom of the ship.

-Nine men died in the attack, but Captain McVay was able to save his ship and prevent greater loss of life.

-It was only very skillful damage control that allowed them to save their ship, and they limped all the way across the Pacific.

They couldn't go faster than about 9 knots on the way back, and they made it.

-Once they reached San Francisco, Indy spent the next three months undergoing repairs and upgrades while a third of the crew was replaced, mostly by sailors who had never seen action.

-We're talking 17-, 18-, 19-year-old boys straight out of boot camp, have never been to sea, have no idea how to sail a ship.

-The guys that I went on board with, they were all kids just out of school, just like me.

-Training this green crew was suddenly cut short when Captain McVay is given a secret mission -- to deliver a mysterious cargo to the far side of the Pacific.

-And so he gets called up to the admiral's office, and he says, "We need you to get across the Pacific as quickly as you can."

And they tell him, "Every day we cut off transporting this package is a day that's cut off the war."

That's all they tell him.

-I was on leave that night.

When I got back to the ship, they were throwing stuff off.

I mean, we were in a big hurry to do something.

-The package consists of two pieces.

One is a large wooden crate, 15 feet by 15 feet.

-Along with the crate comes a strange metal canister just 18 inches high but heavier than lead.

-And they actually weld this down in the flag lieutenant's quarters, and McVay is given these orders -- "If your ship sinks, these need to go into a lifeboat."

[ Laughs ] So he knows whatever it is, it's important.

-All this strikes the crew as very unusual.

They know that something's up, but they have no idea.

-Well, we tried to guess what was in the crate.

Nobody was even close.

-In fact, this canister is filled with uranium-235, and the crate contains the components of an atomic bomb, a weapon so secret that the captain and crew have never even heard of it.

They're bound for Tinian Island, a forward base for American bombers attacking Japan.

-The Manhattan Project folks knew they needed to get this atomic bomb to the Western Pacific so that it could be used.

They needed a fast ship to get it there, and the Indianapolis just happened to be finishing up its repairs at Mare Island.

Serendipity put it at the right place at the right time.

♪♪ -As Indianapolis steams out of San Francisco, McVay doesn't know that a historic event has taken place just hours earlier in New Mexico -- the detonation of the world's first nuclear weapon.

[ Explosion ] -All he knew was he needed to cross the Pacific as quickly as possible, and what they did was, they kept up flank speed all the way to Pearl Harbor.

-When we left San Francisco, we were highballing.

I couldn't believe how fast she was going.

-It was the fastest any ship had ever crossed from California to Hawaii, and that record stands to this day.

They averaged 29 1/2 knots across the Pacific.

-After a stop at Pearl Harbor, Indianapolis arrives at Tinian Island on July 26th to drop off that secret cargo.

-They deliver the atomic bomb, and then their assignment is to go to Guam and get their final assignment to join the Japanese invasion forces.

-Captain McVay is ordered to sail west from Guam to Leyte in the Philippines, 1,300 miles.

-McVay knows that it's been several months since he's been in theater, and the dynamics in the theater have changed.

So he goes up to the operations and the intelligence centers to get briefed up on what's changed since he left, and he gets some intelligence on where the Japanese forces are, and he asks specifically about the submarine threat.

-He's told there is no threat from submarines, and he believes it.

As a former intelligence officer, McVay is well aware that the Allies have cracked the Japanese naval code and should know the whereabouts of enemy ships.

So when the Indy is not assigned an escort for the voyage, he's not too worried.

-He actually didn't think an escort was necessary.

Since he was told there were no submarines to worry about, why would he need an escort?

-McVay's intelligence report mentions only three minor enemy contacts, but intercepted Japanese communications tell a different story.

A squadron of submarines is on patrol in the waters between Guam and Leyte, and American intelligence knows exactly which subs are there.

Nonetheless, the Navy fails to pass on the information.

-So they, in fact, knew that there were four Japanese submarines in the vicinity and had intelligence that there was one actually near the route that the Indianapolis was transiting, and nobody said a thing.

-So basically they are sending us out in harm's way unescorted.

♪♪ -If the crew of Petrel can find Indianapolis, it will lie 6 kilometers, 3 1/2 miles, below the surface.

That's three times deeper than the Grand Canyon.

-People don't realize that the pressure at those depths are, you know, 10,000-plus pounds per square inch, and what we do at those depths become routine for us, but for others, I mean, people will never go there.

-The pressure is enough to cause steel hulls to implode and rupture the wiring and hydraulics on most underwater vehicles.

But Petrel carries a pair of search tools that can operate at those crushing depths.

They're protected by titanium alloy hulls and packed with a molded-glass foam for buoyancy so they can search the seafloor for long periods of time.

[ Beep ] -Dan, you on comms?

-The AUV, or autonomous underwater vehicle, is an untethered drone equipped with side-scan sonar.

-You send it on its way, and 20 hours later, you recover it, download all the data, swap out the batteries, and send it back on its way.

-As the AUV travels along a programmed route, its sonar emits pulses of sound.

Their echoes form an image of the seafloor and make it possible to distinguish human-made objects from the surrounding geology.

If the images reveal an interesting target, Petrel's crew can deploy their ROV, a remotely operated vehicle, tethered to the mother ship by miles of cable.

-The ROV is supplied with power through an umbilical.

We send power down that cable, and that power enables the thrusters to work.

The cameras send their signal up through fiber optics back to the surface, and that's where we distribute it and record it.

It's 6,000-meter capable.

-You can probably count on your hand how many ROVs are currently operating to that depth today, so it's very rare.

All the planning has been done on... -Petrel also carries a team that's expert at locating long-lost artifacts in the deep ocean.

-Yeah.

That's it.

It's right there.

Yeah.

-Paul Mayer has taken the lead on researching Indianapolis's history and its possible location.

Gary Kozak is a sonar specialist.

-Back in 2000, everything seemed to be in this one area, in this... -Curt Newport has been involved in previous searches, so he's got that experience.

You know, he's also a significant knowledge base on the Indianapolis.

-In 2000, Curt led his own unsuccessful expedition to find Indianapolis, exploring a 1,000-square-mile search area.

This time, he's optimistic they'll have better luck.

-Where we're searching for this ship is a result of a lot of analysis.

There's this one particular area that we think this ship probably sank in.

-The question is, is our research right?

We think it is, but time will tell.

-That's where the attack was.

That's... -The Petrel itself and its capabilities and the assets we've got and the research we've done are the culmination of, you know, two years' worth of hard work.

I think we got a great chance of finding this.

♪♪ [ Beeping ] ♪♪ -Indianapolis sailed out of Guam nearly 36 hours ago.

The night is cloudy.

Visibility is low.

Captain McVay retires to his quarters at 8:00 p.m. after giving orders to pick up speed.

He's eager to reach Leyte by Tuesday morning for target practice.

Around midnight, conditions change just for a few minutes, and someone is watching from an enemy submarine.

-The sky does open.

The moon does come out.

And not far away, Commander Hashimoto of the Japanese navy rises and spots a smudge on the horizon.

-And through the periscope, he gets a pretty good view of the ship that's coming towards him in such a way that it's going to put him in a perfect firing position.

-Mochitsura Hashimoto has commanded submarines for three years, but he has not yet scored a kill.

Now he has a chance to redeem himself.

-And then, as the ship gets closer, he realizes there is no escort.

He cannot believe his luck.

♪♪ [ Torpedoes firing ] -Hashimoto fires several torpedoes.

We know at least two hit the starboard side.

♪♪ -The first torpedo hits the bow of the ship, allowing all the water to flood inside.

The second torpedo hits the forward boiler rooms, shuts down three of the four engines, but the fourth engine is still turning.

With that screw driving the ship forward, that was pushing even more water in and causing the flooding to accelerate.

-It's ingesting water by the ton.

Men are running around dogging hatches, which means they're sealing other men to their fate in order to save and compartmentalize the ship.

It's happening very quickly.

-All electrical power is out.

The only lights that we've got is the infernos below deck.

All of that water is coming in.

The bow is going under.

-Captain McVay was hoping that they just needed to do the same kind of damage control that they had done in Okinawa and that they would survive this event, as well.

It only took a few minutes and a few reports from his officers to convince him, no, this is very, very different, and they were going down.

-Abandon ship!

[ Indistinct shouting ] -"Abandon ship!

Abandon ship!

Abandon ship!"

You could hear, and maybe as it got closer, boys are repeating, "Abandon ship!"

-When it give that big list, I know the ship is going down.

Then somebody hollered, "Erwin, you better get off."

That's when I run down the portside and dove in.

-Then by the time I made my way back to the fantail, she was laying over on her side, and the mast was already in the water.

I ran down the side of the ship to the quarterdeck, and that's where I went off.

I was still 30, 40 feet off the water.

When I hit the water, somebody hit me, drove me down.

-I just started swimming as fast as I could to get away from the ship and turned around, and I just saw the fantail going down with shipmates still jumping off of it.

-There was guys still coming off, like ants on a stick, and she was straight up in the air.

-Everyone was looking out into maybe what is the end of life.

Hell, I'm praying, and I tell the Lord, "I don't want to die."

-This warship that had lived through 10 great battles during the war is suddenly now, in 12 minutes, sinking in some of the deepest ocean on Earth.

-I looked back another few minutes later.

She was gone.

-Captain McVay is among the last to leave the ship moments before it sinks.

900 sailors and Marines are adrift in the Philippine Sea 650 miles from the nearest land.

♪♪ ♪♪ The Petrel team has just begun to look for the remains of Indianapolis.

-We need to talk about where we think the best probable position is for the sinking, and with that, then we can determine our search areas.

We'll have a primary, a secondary, a... -Exactly where in this featureless sea should they begin?

There is no easy answer.

-But they talked about 12-foot seas, you know?

-All the paperwork is lost, so basically we have nothing but the recollections of the survivors.

When Captain McVay was picked up, first thing he said, "We were exactly as routed."

But we don't have any of the supporting historical documents.

Their deck logs were gone.

All their records were gone.

So it was really an imprecise location at the beginning.

-Based on Captain McVay's own account of the sinking, the Navy determined an approximate position along the ship's assigned route between Guam and the Philippines, known in the Navy as the Peddie Route.

That's where Curt Newport began his own unsuccessful search.

-Captain McVay was in the water for four days, so I think anyone, including Captain McVay, you know, coming out of the water after that would not be a trustworthy source for where he was.

-There is something they can pinpoint with relative certainty -- the places where the survivors were first spotted and where they were picked up.

-So this is to the middle of the survivor area on the third, and then you go four days to the... -The men were widely scattered in at least six separate groups, and they drifted in different directions during their time in the water.

So working backwards from their various locations to the site of the sinking involves a lot of calculations and some guesswork.

The National Oceanic and Atmospheric Administration has data on the normal currents and winds in the area.

That should make it possible to calculate how far and in what direction the men drifted in the days after their ship went down, at least in theory.

-And if you look at all the logbooks, they're constantly blowing out of the north and northeast, so they should be over here somewhere.

-Right.

I think we're all in agreement.

Longitude looks pretty good.

It's pretty close, right?

Now we need to try and bracket in latitude.

-There's another piece to this puzzle, a clue that only emerged in 2016.

-The captain, in his oral history right after the sinking, talked about passing an LST the day that they were sunk.

-There were hundreds of LSTs, short for Landing Ship, Tank, transporting vehicles and troops around the Pacific during the latter days of World War II.

To figure out where Indianapolis encountered that LST, you have to know which one it was.

After a lot of digging, Dr. Richard Hulver of the Naval Historical Heritage Command comes up with a possible answer.

-I did what basically any person would do these days.

I went to Google, and I was Googling every version of LST and Indianapolis, and I found a Memorial Day blog that this fudge shop owner had posted about his story his father told him of being on this LST that had passed Indianapolis, supposedly, on her last day.

So I was able to, like, find muster rolls with the sailor on there, Sure enough, he was a passenger on LST-779.

I went to the National Archives.

I pulled the logbooks for 779, and Indianapolis was supposed to have passed LST-779 around 1300, so about 11 hours before Indianapolis was sunk.

Their noon coordinate was slightly south of Route Peddie, so it sort of gives us an idea that Indianapolis might not have been directly on Peddie but probably a little south and a little further ahead of schedule.

-So joining both the LST information with the survivor-pickup information and the current information gives us a much better point and direction on where the Indianapolis possibly was.

[ Indistinct talking ] -Putting all the pieces together, Rob Kraft reaches a decision.

They'll look for Indy a little south of the Peddie Route and farther west than the official Navy position.

♪♪ [ Indistinct talking ] [ Beeping ] The crewmen who made it into the water alive do their best to keep together in the darkness, but since Indy was still moving as they abandoned ship, they end up split into several groups of different sizes.

They're scattered along a three-mile line, cut off from each other by the dark pitching seas.

As the hours pass, they continue to drift farther apart.

-[ Coughing ] -Many of the men are gravely injured, suffering from severe burns, broken bones, and lacerations.

Some will not survive the night.

-Nobody knew what to do or how to do it, even the guys that were veterans and been out in the war zone all the whole war.

They never had to go through anything like that.

-As dawn breaks Monday morning, their first day in the water, the survivors can see that they're surrounded by a toxic oil slick stretching in all directions.

-When the torpedo opened up a hole in the ship, one of the things it opened up was the ship's fuel oil tanks, and this kind of oil is called bunker oil.

It was very thick, almost like a syrup.

-That first day, you can imagine.

You've got all of that oil in your eyes.

You've got that salt water.

-There's a lot of oil, and I swallowed some of it.

Didn't take me long to throw it up.

-The men can only hope that they'll be rescued soon.

They don't realize that no one knows Indy is missing.

No one is searching for them.

♪♪ 72 years later, the Petrel team has launched its search for the sunken wreck of Indianapolis.

[ Radio chatter ] -Go!

-Their search area is just over 300 square miles, but that's as large as all five boroughs of New York City, and even a 600-foot warship would be easy to miss.

-When you're trying to find something on the seabed, you use an AUV to do what we call mowing the lawn.

When you mow your lawn, you push your lawn mower down one section of the grass, and you'll come back the opposite way, and you continue that process until the entire lawn is mowed.

Well, we do the same thing in a survey with the AUV.

-Once the AUV has returned to the surface, its data must be analyzed so they can figure out what they've got.

-We downloaded some data as fast as we can.

We bring it into a program to make a map out of it, just stitch it all together in something that a human eye can recognize.

-The AUV has completed its survey of the first search box, a section of about 54 square miles, and so far, they've seen nothing but rocks and sand.

But when they examine images from the second search box, they spot a shape that looks distinctly ship-like.

-So, this particular contact is approximately 60 meters long by about 50 meters wide, so it's certainly not big enough to be the entire ship, but it could be a part of the vessel.

-Right on the edge.

If we wouldn't have done that pass... -Since it's on the edge of the sonar data, we can't see what's beyond it, so we've just got a very small sample of something that could be much larger.

-Very good, first contact to go look at.

-It's an intriguing find but too far from the AUV to get a clear sonar picture.

-We have to go look at it with the ROV.

That's the only way to be absolutely certain of what it is we're seeing on the sonar.

-This is the core of their mission, deploying the ROV to examine a mysterious contact.

But as they unspool the ROV's tether, a winch malfunctions.

-This gearbox here is all that stands between us and 6,000 meters, the ROV, so if this fails while we're at depth, this is a real problem.

-Hundreds of miles from shore, they try to jury-rig a solution.

Meanwhile, they rely on the AUV to scour the search grid.

♪♪ Five days pass, and they haven't found anything else worth investigating.

-To date, we still only have one really good target of interest.

Everything else, the seabed is pretty much benign, clear of targets.

All we have is geology down there, so... -They'll make another pass on that mysterious target with the AUV's sonar and a new tactic.

-We'll go run high frequency on it, meaning that we'll run shorter range scale, and we'll get lots of looks at this target.

If we had the ROV working right now, it'd be on its way.

Yeah, it's frustrating.

-In the Philippines, Tuesday morning comes and goes, but Indy hasn't arrived at Leyte as scheduled, and no one has noticed.

-During this point in the war, there was thousands of Navy ships in the Pacific, and every time a ship departed or arrived in a port, a message was sent out, and with that many ships, there were so many messages that the messages were just getting ignored, so the Navy changed the procedure and says, "Let's stop sending all these messages, so if a ship departs as scheduled and arrives as scheduled, no message is necessary."

-This young officer interprets that to mean, when he sees the Indianapolis not in its berth on its arrival date, "Oh, therefore, the nonarrival shall also go unreported."

[ Chuckles ] [ Beeping ] -Just 10 days after the rescue, a naval board of inquiries convened to investigate the sinking and find out who was to blame.

The board recommends that Captain McVay face a court-martial, but the Pacific fleet's two top admirals, Spruance and Nimitz, urge that he simply be given a reprimand.

They are overruled by Navy Secretary Forrestal, and a court-martial is scheduled for December.

It is unprecedented.

No other captain of a Navy vessel lost in war has ever been court-martialed before, but this sinking is an unprecedented disaster.

-It's such a calamity.

Newsweek and the newspapers of the day are writing about it and wondering, why have so many young men perished at the end of the war?

So there is this pressure to place blame on McVay.

-McVay himself is neither surprised nor bitter about the Navy's decision.

-When you're the captain of a ship, if a sparrow drops dead on the deck, it's your problem.

And that's how McVay felt, that somehow there might have been something he could have done to prevent this tragedy.

-He's resigned.

It's almost like he welcomes what's coming.

They only had a couple of days to prepare their defense for court-martial.

His defense counsel asked for additional time.

The court granted one extra day, so that gave them three days to prepare their defense.

-McVay faces two charges -- failure to give the order to abandon ship and hazarding his ship by failing to take preventive measures against submarine attack.

-In order to avoid attack by submarines, surface ships steered what was called a zigzag pattern.

It involved random maneuvers around their base course so that a submarine could not predict where they would be going.

-In fact, McVay was never told that submarines were patrolling in the area, and his orders specified that zigzagging was at the discretion of the commanding officer.

-That's something that was completely in his discretion, and if he felt that the weather conditions did not merit zigzagging, he didn't have to.

-Since a zigzag route slows down a ship's rate of advance and McVay wanted to reach Leyte on schedule, he did what most captains would do to make up for lost time.

He stopped zigzagging at night if skies were cloudy and his ship couldn't be spotted.

-For decades, the Navy insisted that he was not court-martialed for having his ship sunk.

He was court-martialed because he didn't zigzag.

The survivors are saying, "Come on, so if we would have made it to Leyte but we hadn't zigzagged, you would have court-martialed him?"

Of course not.

In point of fact, submarines had long since developed a tactic of spreading a salvo of torpedoes against zigzagging ships.

It almost guaranteed a hit, regardless of whether the ship was zigzagging or not.

-A controversial witness is called to the stand to testify against McVay... -[ Speaking Japanese ] -...Mochitsura Hashimoto, Commander of I-58, whose torpedo sent Indianapolis to the bottom.

-Op-ed pieces were written in almost every major newspaper in the country about how offensive this was, the only time an enemy combatant had ever been called in to testify against an American warrior.

-Never happened before, never.

And the captain told the court, "It's a disgrace to the United States to have me here."

-Hashimoto testifies that, in fact, there was nothing that Captain McVay could have done to evade his firing of the torpedoes.

-I actually took the exact scenario presented by the I-58 and the Indianapolis, and then I modeled different scenarios for the Indianapolis, presuming it zigzagged.

As it turned out, torpedoes number two and three were pretty sure hit.

If you sped up, torpedoes one and two would have hit.

If you'd have slowed down or turned away, torpedoes four or five would have hit, and so...

In every case, at least one torpedo would have hit them.

And sadly, this is not something that they did in McVay's defense during his own court-martial.

-In the end, the court clears McVay of failing to order abandon ship, but he is found guilty of hazarding his vessel by failing to zigzag.

His sentence seems light, a reduction in seniority, putting him farther back in line for promotion.

-It's basically a slap on the wrist, but the fact is, when you're convicted by a court-martial, you are, by point of law, a felon in most states in the country.

Captain McVay seemed to accept it much more readily than the survivors did.

The survivors didn't like that one bit.

-There were certainly many factors involved in the Indianapolis tragedy, issues that never made their way into the court-martial.

Intelligence about Japanese submarine activity was never shared with Captain McVay, and a destroyer escort was never offered.

While the Navy had broken Japanese codes, it wanted to keep that a secret.

-Intelligence does nobody good if it's kept in a locked green room, behind a green door.

It's only when it's operationalized does it actually do any value for our military forces.

-For the survivors, it's no mystery why they spent so much time in the water and why so many of their shipmates died.

-You know, the fact that the sailors were in the water for almost five days caused all of those deaths, and that was caused by a delay in recognizing that the ship was missing and a delay in rescue, and nobody was punished for that.

-What I'm saying to you, a lot of men died between Tuesday afternoon and Friday morning.

-For most of the survivors, their captain remains blameless, despite the outcome of his trial.

-I think they used him for a scapegoat, for losing all those men and losing that ship, and they had to blame it on somebody.

It just wasn't his fault.

-McVay retires from the Navy.

But the Indy's tragic end will continue to haunt him and his crew.

-And so the troops came home, home from Iwo Jima and... -When we went home after the war, they said, "Go home and forget about it."

Well, it's easy for them to tell me to forget about it 'cause they weren't there.

And we didn't talk about it.

You know, my mother and dad died not knowing what happened, and they never did know about it.

-Guys would say, "I can't go swimming anymore.

I can't even take a bath because being in that much water brings back too many memories."

-Me and water don't get along.

-Noise would trigger things.

Drive a car and hit a metal in the road or on a bridge, and, you know, you want to hit the deck.

Yes.

It bothered me.

-There's damn few days that I don't think of the water, being rescued, or some part of the story.

-I could talk to you forever about it, and you still don't know what we went through, to be there at 17 years old, to see stuff that we should never have seen.

-For Captain McVay, the memories are especially painful.

He bears the burden of losing 879 of his men.

And he has to deal with the grief and anger of their families, many of whom blame him.

-He wrote a letter to every one of those lost-at-sea families and conveyed his condolences.

Almost immediately, letters started coming back the other way.

Most of them were very ugly.

-He'd get hate mail, and they'd blame him for everything.

-The man had been convicted by his own Navy.

The Navy seemed to hold him responsible for the death of their loved ones.

Why should they think otherwise?

-Every Christmas, that guy might get 100 or 200 Christmas cards.

-"Dear Captain McVay..." -"Dear Captain McVay..." -You know what they'd say?

"If it wasn't 'cause of you, my husband or my son would be alive today."

-"...would be alive today, and would be celebrating Christmas."

-"I hope you're having a merry Christmas.

We would be, too, if you hadn't killed my son."

-"We would be, too, if you hadn't killed my son.

[ Bell ringing ] -By custom, the ship's bell is used to signal the change of watch, but there is another naval tradition that connects this artifact and this ship to the man who was its commander.

-Every day when you walk aboard your vessel, your ship -- you're the captain -- a crew member rings a bell, ding-ding, ding-ding, and they announce on the ship's announcing system, "Indianapolis arriving."

They don't say, "Captain of Indianapolis."

They say, "Indianapolis," because the captain personifies the ship.

That's the naval lore.

And so every day I came aboard that ship and I heard, "Indianapolis arriving," I thought of McVay.

I thought of the fact that he heard the same words.

-After McVay's death, many of his crewmen take on a new mission -- to exonerate their captain and clear the stain of the court-martial conviction from his record.

-These guys were fighters in the water, and they became crusaders later in life, both in the name of their ship and the name of their captain.

And so they stood behind him, and they began to fight almost immediately.

-We fought the Navy.

We fought the Pentagon.

We fought Washington, anyone that would hear us.

We knew that it was a miscarriage of justice on the part of the Navy to court-martial a good captain.

-Eventually, the survivors enlist the help of Bill Toti, captain of the other Indianapolis.

He has forged a special bond with the men who served on the original Indy.

-When I got to know the survivors better, they started referring to me as Skipper Bill, and they started treating me almost like I was their, you know, long-lost captain.

I felt an obligation to them.

And when I first started looking into the story and the exoneration, I didn't know what I'd find.

You know, I was looking for an opportunity to have the Navy admit that perhaps justice wasn't served and maybe get the Navy to soften its hard line and throw a bone to the survivors.

-12-year-old Hunter Scott was inspired to find out the truth about Captain McVay.

-As Bill Toti pursues official avenues inside the Navy, another champion emerges.

-The survivors started sending me these articles about this 13-year-old boy named Hunter Scott, who had made it his school project to shine a light on the plight of Captain McVay, and this kid was going gangbusters.

-Please welcome Hunter Scott.

Hunter, come on.

When I left command of the submarine, Hunter was still out there publicly rallying support, and my work was very much behind the scenes.

-When the Navy refuses to reopen its investigation or drop McVay's conviction, the effort turns to Congress.

-I think the survivors of USS Indianapolis, as they sought for years to clear Captain McVay's name, were also fighting to clear their own conscience, to lift a cloud that had fallen over their ship.

-In May 1999, a resolution is drafted to clear Captain McVay.

-Senator John Warner allowed the exoneration language to go to the full Senate for a vote, and it passed, and President Clinton signed it into law.

And so that's how Charles Butler McVay III was exonerated for the sinking of his ship.

-The only thing, it's too late for him because he's already put his revolver to his temple and pulled the trigger.

But it did something for we survivors and even for relatives of those lost at sea.

-I do believe this brought closure, both to the survivors, but I think more so to the lost-at-sea families because for them, this is the final resting spot for their loved ones.

This is hallowed ground for them.

-I'm sure it helps those people to know that the ship has been found, and I'm proud for those people, but I'm real sorry for my shipmates that lost their life.

-People think I'm a hero.

Okay.

I had bad luck.

I was on a ship that sank.

I swam around there for five days.

I was picked up.

No big deal.

I'm no hero.

I just did my thing.

I want to keep the story alive.

That type of story should be kept alive.
