USS Indianapolis, Portland Heavy Class Cruiser, 5th fleet
Flagship, was stationed out of Mare Island Northern Ca.
She was sunk/torpedoed by Japanese sub
shortly after delivering "the Atomic bomb Little Boy"
that was dropped on Hiroshima...
Largest single loss of life on record for US Navy
Sunk July 30th 1945, in rout to the Philippines,
1,196 aboard, some 317 survived,
300 went down with the ship, remaining almost 900 were in the water,
for 4 days before spotted by aircraft, many sailors died while in the water,
exposure, dehydration or eaten by sharks
The mission was so secretive they weren't missed or
reported as being overdue or late to port...
Sad story...
