On July 30, 1945, the battle cruiser USS Indianapolis was returning from a mission delivering enriched uranium to allied forces in the Pacific. It did not make it home. A Japanese torpedo hit the cruiser on its way back. It sank in minutes. In only 12 minutes, 300 of the 1,200 men died. Nine hundred went into the water, enduring four days and five nights without food, without water, and under the blazing sun of the Pacific. Of the 900 men that went into the water, only 316 survived the lack of water and the sharks. One of those who survived was the chief medical officer, who recorded his own experience. He wrote:

There was nothing I could do, nothing I could do but give advice, bury the dead at sea, save the lifejackets, and try to keep the men from drinking the water. When the hot sun came out, and we were in this crystal clear ocean, we were so thirsty. You couldn't believe it wasn't good enough to drink. I had a hard time convincing the men they shouldn't drink. The real young ones…you take away their hope, you take away their water and food, they would drink the salt water and they would go fast. I can remember striking the ones who were drinking the salt water to try to stop them. They would get dehydrated, then become maniacal. There were mass hallucinations. I was amazed how everyone would see the same thing. One man would see something, and then everyone else would see it. Even I fought the hallucinations off and on. Something always brought me back.
