The attack on Pearl Harbor happened 77 years ago on Dec. 7, 2018.
The Japanese attack on the US naval base in Hawaii killed more than 2,400 American sailors and civilians and wounded 1,000 more.
Japanese fighter planes also destroyed or damaged almost 20 naval ships and more than 300 planes during the attack.
Several photos were captured during the attack, some of which have become iconic of that infamous day.
Here are the stories behind five of those unforgettable images.
A Japanese fighter plane drops what’s believed to be the first bomb on Pearl Harbor on Dec. 7, 1941.
1. The first bomb likely dropped.
The above photo, which was taken by a Japanese photographer, was found by US Navy photographer Martin J. Shemanski at Yokusuka Base near Tokyo Bay shortly after the Japanese surrendered.
The photo shows the Japanese fighter plane (the small black speck that almost looks like a bird) appearing to pull out of a dive after dropping the bomb on Battleship Row. Another Japanese fighter plane can be seen in the upper right corner.
Shemanski and four other US military photographers were ordered to go through Japanese photo processing labs after the surrender, and he found it torn up in a trash can.
“It had a torn photo in it,” Shemanski told the Press-Enterprise in 2015.
“I picked up a couple pieces and I got a shot of a torpedo hitting the Oklahoma. I thought, ‘This is Navy intelligence,'” he added.
The USS Oklahoma was a Nevada-class battleship that was sunk during the attack on Pearl Harbor.
Shemanski told the Press-Enterprise that the picture was torn up in about 20 pieces.

2. The USS Shaw explodes.
This photo shows the USS Shaw destroyer exploding while in floating dry dock.
Between 7:55 a.m. and 9:15 a.m., the Shaw was hit by three bombs released by Japanese fighters in steep dives from approximately 1,000 feet, according to the US Navy action report.
The Shaw immediately caught fire, and the ship was abandoned. About 20 minutes later, as sailors were trying to flood the dry dock to save the ship, the forward magazines blew up, which is pictured above.
The blast destroyed the bow and damaged the dry dock and a nearby tugboat.
Initially thought to be a loss, the Shaw was eventually repaired and later took part in several engagements in the Pacific, including the biggest naval battle of all-time, the Battle of Leyte Gulf.

3. Battleship Row on fire.
The picture above shows the USS West Virginia and USS Tennessee battleships on fire in Battleship Row.
Battleship Row was where seven US Navy battleships were moored on the eastern side of Ford Island (shown in the first picture), which rests in the middle of Pearl Harbor.
These seven battleships alone (the USS Arizona, USS West Virginia, USS Oklahoma, USS Tennessee, USS Maryland, USS California, and USS Nevada) were equal to about 70% of Japan’s active battleship fleet.
As such, these ships were the main target for the Japanese fighter planes, with 29 of Japan’s 40 torpedo planes ordered to attack it.
Each Japanese torpedo plane carried one Type 91 aerial torpedo with a warhead of 992 pounds, and 21 of them hit their targets. Japanese bombers then flew in after the torpedo plane attacks and caused further damage.
In total, the Japanese sunk the Oklahoma and Arizona, and damaged the other five ships.

4. Rescuing sailors from the USS West Virginia.

The USS West Virginia was a Colorado-class battleship that was hit by at least seven torpedoes and two bombs during the attack.
When the West Virginia was raised from the water for repairs six months after the attack, they found the bodies of three US Navy sailors who had been trapped in a compartment for 16 days, according to the Honolulu Advertiser.
US Marines standing guard had heard the sailors banging for help, but they couldn’t do anything. No one on guard wanted to go near the ship and hear the sounds.
When the sailors bodies were finally recovered, rescuers found a calendar on which the sailors had marked their last days.
The West Virginia was later reconstructed and put back into the war in 1944, supporting operations in the Philippines and Okinawa.

5. The sinking USS Arizona.
This photo shows the USS Arizona battleship sinking in Battleship Row after it was hit by eight Japanese bombs and one torpedo.
One of the bombs went through a magazine and ignited cordite, which caused an expansion of gases and then a huge explosion.
The Arizona quickly sunk with 1,177 of the 1,512 personnel on board, which was about half the number of people killed in the entire attack.
The battleship burned for more than two days.
This is perhaps the most iconic taken during the Pearl Harbor attack. The Arizona still lies in the harbor as a national memorial.
