In the vast and unpredictable oceans, the numbers tell a chilling story. In 2023 alone, there were 69 unprovoked shark bites, leading to 10 tragic fatalities.1
While the chance of encountering one of these majestic creatures in a life-threatening situation sits at just 1 in 4.3 million, the haunting memory of the USS Indianapolis reminds us that such encounters can result in unimaginable horror. Here’s what happened.
A Doomed Mission
The USS Indianapolis had just completed a secret mission delivering components for the atomic bomb that would later be dropped on Hiroshima. Disaster struck on July 30, 1945, as the ship sailed towards the Philippines.
A Japanese submarine torpedoed the Indianapolis, sinking it in a mere 12 minutes. Of the 1,195 men aboard, around 300 went down with the ship, while the remaining 900 were left adrift in shark-infested waters.(ref)
The Indianapolis was chosen for this top-secret mission due to its speed and the ability to travel unescorted. It took just ten days to transport the uranium-235 and other parts of the atomic bomb from California to Tinian in the Mariana Islands.
After successfully delivering its deadly cargo, the Indianapolis sailed to Guam and was then dispatched to the Leyte Gulf in the Philippines to prepare for the invasion of Japan.
A Feeding Frenzy
As the men struggled to stay afloat, the sharks began their assault. The scent of blood and the sailors’ thrashing triggered a feeding frenzy, with sharks swarming the area. Oceanic whitetip sharks, known for their opportunistic feeding behavior, were likely the primary culprits.
Survivor accounts paint a chilling picture. Corporal Edgar Harrell recalled, “You’d hear a blood-curdling scream and see him go under. He would come back to the surface, but you’d see fins and realize his legs were gone, or he just had a torso.” (ref) The men were too terrified to move, knowing that any activity could draw the attention of the predators.
The crew faced exposure, dehydration, and saltwater poisoning in addition to the constant threat of shark attacks. Many began to hallucinate from drinking seawater, some even violently attacking their fellow sailors. The sharks continued to circle, occasionally darting in to claim another victim.
A Tragic Toll
For four harrowing days, the survivors battled exposure, dehydration, and relentless shark attacks. By the time rescue finally arrived, only 316 men remained. It is estimated that up to 150 sailors were killed by sharks, making it the deadliest shark attack in history.
The delay in rescuing the survivors was due to a tragic series of miscommunications and oversights. The ship was not reported missing for several days, as it was traveling alone and was not expected at its destination for some time. When the survivors were finally spotted by a passing aircraft, many were delirious, injured, or near death.
The sinking of the USS Indianapolis and the subsequent shark attacks serve as a grim reminder of the horrors of war and the power of nature. The tragedy also highlights the importance of swift rescue operations and the need for improved safety measures to prevent such devastating losses in the future.
