On February 17th 1864, the city of Charleston, deep in the throes of the Civil War, made history with a small 8 men crew that was stationed in a revolutionary new vessel in the Charleston Harbor. The H.L. Hunley was an experimental new addition to the Confederate's fleet of warships, but on that clear but chilly evening, it would land in military history books for generations to come as the first submarine to successfully take down another wartime vessel.
