Indianapolis sank rapidly, and many survivors remained in the water for days before being discovered. Of roughly 1,195 people aboard, about 救? 316 were eventually rescued, while hundreds died from injuries, exposure, dehydration, and shark attacks. The disaster became one of the most notorious American naval losses of the war.
