Seriously, Juneau was vaporized by I-26's torpedo.
not only that the her explosion was so powerful it sent large fragments of her into another ship the CA 38 San Francisco one of which broke the legs of a crewman on the San Francisco her demise was so sudden and total it was assumed no survivors to risk sticking around and risk further attacks for a survivor search.
100 men survived the Juneau destruction when they finally were found by chance 8 days later only 10 survived between injuries exposure and shark attacks.
