Those who managed to escape from the brown boat soon had something bad to worry about. The blue waters of the Pacific that at first seemed to be a safe haven as their torpedo boat turned into a fireball were about to take on a frightening shade of red. The submarine attack detonated a tank containing 3,500 gallons of aviation fuel and the cold ocean was the only place to leave. They soon discovered that it was not the temperature that was causing the problem, as the jaws of some scary beasts lurk.

To make matters worse, the ongoing attacks lasted about four days, as the weakened troops began to rise as the sharks refused to stop circling. It is estimated that more than 150 were lost, but some survived to tell the story. Sergeant Edgar Harel survived the worst shark attack of all time ( Picture: Ohio Valley Military Company / You) Sergeant Edgar Harel said he could still hear the screams of friends clinging to each other as the creatures began to tear pieces from their legs. “You heard a blood clot and you looked and you saw someone going down – all we heard was live men eating, every day, every night,” Harel said in 2019.

He added: “I swam away from the ship and to a group of marines who had already left the boat – one was seriously injured and died in my arms within the next hour.” Harel, the last survivor of the attack, died in May 2021.

The troops gathered together in the ocean in the hope that they could scare the predators, but many could not avoid the food frenzy. Of the 80 men who gathered in the water with Mr. Harel, only 17 were alive three days later.

Those who did not go did not survive, he said. The small group was spotted the next day by an American bomber patrolling anti-submarine. Mr Harel later said: “We were lucky – when you take out about 900 boys out there who are rotting out of misery, the sharks will swim out of there and attack whatever is in their way.” Hungry sharks killed most of the crew that survived the largest human attack ever recorded (stock image) ( Picture: Getty Images / Culture RF) Of the 1,195 crew members when the ship was torpedoed, only 316 survived. In August 2017, the wreckage of the ship was found 18,000 feet below the surface. read more 13-Legged Monster “Jumbo Jaws” Great White Shark Spotted on Radar in Shallow Water read more Visitors to the beach say “alien creature from the depths” with strange teeth and lips washed in the storm
