In the final days of the war, the U.S.S. Indianapolis completed a top secret mission to deliver components of the atomic bomb used in Hiroshima to U.S. forces in the theater. After dropping those components off at Tinian in the Marianas Islands, Indianapolis headed to Leyte, an island in the Philippines, when it was torpedoed and sunk by a Japanese submarine just after midnight on July 30, 1945. Around 800 of the ship’s 1,196 Sailors and Marines survived the sinking, but after four to five harrowing days in the water, suffering exposure, dehydration, drowning, and shark attacks, only 316 survived.

While reviewing the Navy’s holdings and other information related to Indianapolis, NHHC historian Richard Hulver, Ph.D., found a blog post and photo online that recounted the story of a World War II Sailor whose ship passed Indianapolis less than a day before the ship was sunk. This corroborated an account by Indianapolis Captain Charles McVay, III that his ship passed an unspecified LST approximately 11 hours prior to the sinking. Hulver located the Sailor’s service record from the National Personnel Records Center which identified the Sailor as a passenger on tank landing ship USS LST-779 during the period in which Indianapolis sank. That sent Hulver to the National Archives where LST-779’s deck logs confirmed the story.

 The meeting between Indianapolis and LST-779 has been seemingly overlooked in previous studies of Indianapolis.

 
 Hulver continued, “The LST-779 data sheds new light on where Indianapolis was attacked and sunk.” This brings us closer to discovering the final resting place of the ship and many of her crew. 

Although the location of Indianapolis is known to be in the Philippine Sea, two previous attempts to find the wreck have failed. In July–August 2001, an expedition sought to find the wreckage through the use of side-scan sonar and underwater cameras mounted on a remotely operated vehicle. Four Indianapolis survivors accompanied the expedition, which was not successful. In June 2005, a second expedition was mounted to find the wreck. National Geographic covered the story and released it in July. Submersibles were launched to find any sign of wreckage. The only objects ever found, which have not been confirmed to have belonged to Indianapolis, were numerous pieces of metal of varying size found in the area of the reported sinking position.

Hulver summarized the historical literature, conducted archival research, and prepared a report incorporating the new information gleaned from LST-779’s brief encounter with Indianapolis. NHHC’s summary was published online as part of a project to consolidate the entirety of NHHC’s holdings on Indianapolis into an easy-to-navigate, online resource (http://go.usa.gov/xr57m) prepared in advance of the 71st anniversary of the ship’s loss July 30. 

The USS Indianapolis National Memorial  was dedicated on 2 August 1995. It is located on the Canal Walk in Indianapolis. The heavy cruiser is depicted in limestone and granite and sits adjacent to the downtown canal. The crewmembers' names are listed on the monument, with special notations for those who lost their lives. Image courtesy of Wikimedia Commons.
