In 1784, the ill-fated ship, El Cazador, was headed toward New Orleans from Vera Cruz, Mexico. The ship was laden with 450,000 pesos, which were intended to solidify Spain's holdings of approximately one million square miles: the area today is known as the heartland of America. The vessel and her crew never arrived to help stabilize the economy.

Finally in 1800, with no money to pay his troops, King Charles IV of Spain transferred the Louisiana Territory over to Emperor Napoleon Bonaparte for some minor European considerations. In 1803, only three years later, Napoleon and President Thomas Jefferson struck a deal called the Louisiana Purchase. The fledgling United States purchased these one million square miles for fifteen million dollars.

The El Cazador and its treasure sat on the bottom of the Gulf of Mexico for 209 years before a fishing boat off the coast of Louisiana accidentally discovered it. It's hard to say what would have happened if El Cazador had made it to New Orleans but it could be argued that the loss of this ship did contribute to the unifying of the United States of America.
