Steamship S.S. Republic, 1865

When this Civil War-era side-wheel steamship sank during a violent gale off the Georgia coast in October, 1865, it went down with something other than the ordinary goods most vessels of the era carried. In the case of the Republic, her holds were filled with tons of silver and gold coins and ingots being transported from the West Coast to help rebuild the war-ravaged south, making her loss an incalculable financial blow to the country at a time when it was still struggling to regain its economic legs after four years of civil war. (The only positive thing from the sinking was that the ship’s entire crew and passengers managed to get off safely before the ship foundered, making it one of the few famous shipwrecks that did not result in loss of life.) The ship’s precise location remained unknown until 2003, when she was finally located after an extensive search some 100 miles off the Georgia coast in nearly 1,700 feet of water. The subsequent recovery effort not only yielded one of the largest caches of gold and silver coins in history, but included a fascinating assortment of 19th century goods that revealed much about life in the mid-nineteenth century. By the time the recovery was concluded, over 51,000 U.S. gold and silver coins had been recovered along with nearly 14,000 artifacts, making it not only the richest find in the history of salvaging, but the highest-tech archaeological excavation ever conducted. So successful—and lucrative—was the expedition, in fact, that it set a precedence for the emerging field of deep-water shipwreck exploration and recovery.
