USS Indianapolis CA-35

On July 29-30, 1945 after delivering the Atomic Bomb across the Pacific, the cruiser USS Indianapolis was spotted, then torpedoed, and sunk by a Japanese submarine. From the article:

"The world's first operational atomic bomb was delivered by the Indianapolis, (CA-35) to the island of Tinian on 26 July 1945. The Indianapolis then reported to CINCPAC (Commander-In-Chief, Pacific) Headquarters at Guam for further orders. She was directed to join the battleship USS Idaho (BB-42) at Leyte Gulf in the Philippines to prepare for the invasion of Japan. The Indianapolis, unescorted, departed Guam on a course of 262 degrees making about 17 knots.

At 14 minutes past midnight, on 30 July 1945, midway between Guam and Leyte Gulf, she was hit by two torpedoes out of six fired by the I-58, a Japanese submarine. The first blew away the bow, the second struck near midship on the starboard side adjacent to a fuel tank and a powder magazine. The resulting explosion split the ship to the keel, knocking out all electric power. Within minutes she went down rapidly by the bow, rolling to starboard.

Of the 1,196 aboard, about 900 made it into the water in the twelve minutes before she sank. Few life rafts were released. Most survivors wore the standard kapok life jacket. Shark attacks began with sunrise of the first day and continued until the men were physically removed from the water, almost five days later.

Delayed Rescue

Shortly after 11:00 A.M. of the fourth day, the survivors were accidentally discovered by LT. (jg) Wilbur C. Gwinn, piloting his PV-1 Ventura Bomber on routine antisubmarine patrol. Radioing his base at Peleiu, he alerted, "many men in the water". A PBY (seaplane) under the command of LT. R. Adrian Marks was dispatched to lend assistance and report. Enroute to the scene, Marks overflew the destroyer USS Cecil Doyle (DD-368), and alerted her captain, of the emergency. The captain of the Doyle, on his own authority, decided to divert to the scene.

Arriving hours ahead of the Doyle, Marks' crew began dropping rubber rafts and supplies. While so engaged, they observed men being attacked by sharks. Disregarding standing orders not to land at sea, Marks landed and began taxiing to pick up the stragglers and lone swimmers who were at greatest risk of shark attack. Learning the men were the crew of the Indianapolis, he radioed the news, requesting immediate assistance. The Doyle responded she was enroute.

As complete darkness fell, Marks waited for help to arrive, all the while continuing to seek out and pull nearly dead men from the water. When the plane's fuselage was full, survivors were tied to the wing with parachute cord. Marks and his crew rescued 56 men that day. The Cecil Doyle was the first vessel on the scene. Homing on Marks' PBY in total darkness, the Doyle halted to avoid killing or further injuring survivors, and began taking Marks' survivors aboard.

Disregarding the safety of his own vessel, the Doyle's captain pointed his largest searchlight into the night sky to serve as a beacon for other rescue vessels. This beacon was the first indication to most survivors, that their prayers had been answered. Help had at last arrived. Of the 900 who made it into the water, only 317 remained alive. After almost five days of constant shark attacks, starvation, terrible thirst, suffering from exposure and their wounds, the men of the Indianapolis were at last rescued from the sea.

Shocked Reaction

The impact of this unexpected disaster sent shock waves of hushed disbelief throughout Navy circles in the South Pacific. A public announcement of the loss of the Indianapolis was delayed for almost two weeks until August 15, thus insuring that it would be overshadowed in the news on the day when the Japanese surrender was announced by President Truman.

The Navy, however, was rushing to gather the facts and to determine who was responsible for the greatest sea disaster in its history . who, in effect, to blame. It was a faulty rush to judgment.

Evidence Withheld

It is important to note at the outset that vital information pertinent to determining responsibility for the loss of the Indianapolis was not made public until long after the subsequent court-martial and conviction of Captain McVay. U.S. intelligence using a top secret operation labeled ULTRA had broken the Japanese code and was aware that two Japanese submarines, including the I-58, were operating in the path of the Indianapolis.

This information was classified and not made available to either the court-martial board or to Captain McVay's defense counsel. It did not become known until the early 1990s that - despite knowledge of the danger in its path - naval authorities at Guam had sent the Indianapolis into harm's way without any warning, refusing her captain's request for a destroyer escort, and leading him to believe his route was safe.

Controversial Facts

Captain McVay's request for a destroyer escort was denied despite the fact that no capital ship lacking anti-submarine detection equipment, such as the Indianapolis, had made this transit across the Philippine Sea without an escort during the entire war.
Captain McVay was not told that shortly before his departure from Guam a Japanese submarine within range of his path had sunk a destroyer escort, the USS Underhill.
Shortly after the Indianapolis was sunk, naval intelligence decoded a message from the I-58 to its headquarters in Japan that it had sunk an American battleship along the route of the Indianapolis. The message was ignored.
Naval authorities then and now have maintained that the Indianapolis sank too quickly to send out a distress signal. A radioman aboard the Indianapolis testified at the September 1999 Senate hearing, however, that he watched the "needle jump" on the ship's transmitter, indicating that a distress signal was transmitted minutes before the ship sank, and sources at three separate locations have indicated that they were aware of a distress signal being received from the sinking ship. Its very likely that these distress signals were received but ignored as a Japanese trick to lure rescue vessels to the area.
Confusion on the part of Navy communications and a faulty directive caused the failure of the Indianapolis to arrive on schedule to go unnoticed, leaving as many as 900 men at the mercy of a shark-infested sea. (The faulty directive - which required only reporting the arrival of non-combatant ships - was corrected days after the Indianapolis survivors were discovered to require reporting the arrival of combatant ships as well.)"
