The Confederate Submarine H.L. Hunley actually sank 3 times:
August 29, 1863 - Sank during test dive preparations when dive planes were prematurely engaged.
October 15, 1863 - Failed to surface after a mock attack.
February 17, 1864 - Sank while returning to her base at Sullivan's Island, S.C., after her historic and successful attack on the Union sloop-of-war USS Housatonic in Charleston Harbor.
She was salvaged after the first 2 sinkings and returned to service; however, until she was raised in 2000, her fate remained a mystery for 136 years. Long believed to have sunk as a result of the explosion from her Spar Torpedo, that is now known to be incorrect. She is now known to have survived the attack, and signaled Confederate forces at her base on Sullivan's Island that she was returning after her successful attack on the USS Housatonic. There is strong evidence which has been found during the restoration and preservation efforts (as well as forensic examination of crew remains) that her crew did not drown as believed, but that they died from a lack of oxygen.
the first true submarine.
The CSS Hunley sank four times during its sea trials. Undeterred, the Hunley did sink one Union ship but also destroyed itself.
The Confederate submarine was named for its inventor Horace Lawson Hunley.
It was the H. L. Hunley, a submarine developed by the Confederate navy during the U.S. Civil War. The mission had mixed results, however, because the Hunley sank soon afterwards, and all hands went down with it. The H.L. Hunley was under Confederate Army command because the Confederate Navy wanted nothing to do with it, as they considered submarines too dangerous, and it was dishonorable to attack at sea without showing the flag. Of the crew aboard when the sub made its fateful attack, only one was a sailor, and the rest were army men. It was not until World War 1 that a submarine would better the Hunley's achievement, as the German sub U9 sank three British cruisers and survived to tell the story. Robert Fulton's Nautilus was actually the first submarine to sink a ship, but it was a peacetime demonstration. Earlier than that, David Bushnell's Turtle made the first submarine attack in the American Revolutionary War, but it was unsuccessful, so Hunley was indeed the first submarine to sink an enemy ship.

The most well known thing the Hunley did in the Civil War was to sink the Federal warship Housatonic
I believe it stands for Horace Lawson Hunley, who was the developer of the submarine.
