It was an event launched from Tinian that brought  the war in the Pacific to a close and restored peace to a war weary world. The B-29 Superfortress Enola Gay departed the island in the early morning hours of August 6, 1945 to deliver an atomic bomb which destroyed Hiroshima. Days later a second device was dropped on Nagasaki convincing the Japanese military that hostilities should be concluded. Components of the bomb had been delivered to Tinian days earlier by the United States Cruiser Indianapolis. A little known event involving this warship resulted in the greatest tragedy in the annals of United States naval history.  After delivery of its ominous cargo, the vessel was sunk by the Japanese submarine I - 58 and was the last major warship lost in World War Two. One can only speculate as to the outcome of history had the vessel been sunk before delivering its secret cargo to Tinian.  This article chronicles the events at Tinian that lead to the end of the war and last days of the Indianapolis and many of its officers and crew.
