Numismatic History: The Loss of the 1715 Spanish Treasure Fleet
In the early hours of July 31, 1715, one of the richest Spanish treasure fleets ever assembled was in trouble. Carrying a fortune in gold and silver from the New World, the 1715 Fleet was trying to outrun a storm pursuing it up the Florida Straits. The treasure-laden galleons were not fast enough. By 2 a.m. 100 mph winds, torrential rains, and mountainous waves broke over the Fleet.
