But many questions still remain. Why did they sink? Did they intentionally dive to wait for the incoming tide and for some reason not surface? Or did the Hunley sink immediately and the wreck gradually move the 1000 feet? Whatever the Hunley's fate, it was unique. Safe and usable submarines were far in the future, and the next successful military use occurred in 1914, during World War I. With the Hunley's sinking, the war was almost over for Charleston. New weapons had been developed and used successfully, but none were powerful enough to break the blockade and turn the war around.
