The sinking of the USS Indianapolis by the Imperial Japanese Navy during World War Two was the single greatest loss of life at sea in the history of the U.S. Navy.
Out of a crew of 1,196 sailors, 300 went down with the ship, which sank within 12 minutes of being torpedoed. Hundreds more succumbed to hypothermia, dehydration, starvation, and shark attacks as they waited for five days in the open sea for rescue. Faced with a shortage of life vests and life boats, only 317 sailors ultimately survived the attack.
In a new book, "Out of the Depths," Marine and Indianapolis veteran Edgar Harrell shares his harrowing experience of the wreck, his struggle for survival, and his ultimate rescue.
Below are some of Harrell's photos of the Indianapolis.

Among the many dangers the Indianapolis faced, one of the most terrifying was the Japanese use of kamikaze attacks.

Still, the Indianapolis successfully took part in campaigns as far apart as in New Guinea and the Aleutian Islands.

The Indianapolis' last mission was the delivery of half the world's existing enriched uranium to Tinian Island for use in the atomic bomb Little Boy.

Four days after delivering the uranium, on July 30, 1945, two Japanese torpedoes tore through the Indianapolis.

The ship rolled over and sunk almost immediately. The survivors of the initial wreck found themselves stranded for five days in the middle of the Pacific with almost no supplies, vests, or lifeboats.
