In late July 1945, the
Indianapolis was sent on a high-speed journey to deliver cargo to US air base Tinian in the western Pacific. Nobody on board knew what the cargo was, including the personnel who guarded it round the clock.
It was later revealed that it carried the parts for atomic bombs which would later be dropped on the Japanese city of Hiroshima just a few days later.
On July 30, 1945, the
Indianapolis was torpedoed and sunk by a Japanese submarine. From a crew of 1196 sailors and marines, 300 went down with their ship. Though around 900 men survived the initial sinking, many succumbed to shark attacks, dehydration and salt poisoning soon after. By the time rescue crews arrived, only 316 people could be saved.
The sinking of the USS
Indianapolis marks the greatest loss of life at sea from a single ship in
US Navy history. The echo of the devastating tragedy can still be felt today, with a campaign in 2001 successfully lobbying for the exoneration of the captain, Charles B. McVay III, who had been blamed for the sinking of the ship.
