how many sailors survived the sinking of the uss indianapolis
USS Indianapolis (CA-35) In 1945, the sinking of Indianapolis led to the greatest single loss of life at sea, from a single ship, in the history of the US Navy. The ship had just finished a high-speed trip to United States Army Air Force Base at Tinian, to deliver parts of the first atomic bomb ever used in combat (the United States' Little Boy atomic bomb), and was on training duty. At 0015 on 30 July 1945 the ship was torpedoed by the Imperial Japanese Navy submarine I-58. The ship, on her way to the Philippines, sank in 12 minutes. Of 1,196 crewmen aboard, approximately 300 went down with the ship. The remaining 900 faced exposure, dehydration, saltwater poisoning, and shark attacks while floating with few lifeboats and almost no food or water. The Navy learned of the sinking when survivors were spotted four days later by the crew of a PV-1 Ventura on routine patrol. Only 317 survived.
U-boat Campaign (World War I) In the course of events, German U-boats sank almost 5,000 ships with nearly 13 million gross register ton, losing 178 boats and about 5,000 men in combat.[4]
