Cortés ordering his fleet to be destroyed may be one of the iconic moments in history. In 1519, Hernán Cortés led an expedition of 11 ships from Cuba to Mexico. On arriving in Mexico, the crews found themselves vastly outnumbered by the Aztecs and many were on the verge of mutiny, intending to sail back to Cuba. Cortes ordered the 10 remaining ships of his fleet destroyed. (One ship had already been sent back to Cuba with news of the landing.) There is disagreement as to whether the ships were burned, scuttled or run up on the beach. When reinforcements and supplies arrived a year later, Cortés had those 16 ships destroyed as well.
500 years later, where the ships were destroyed remains a mystery. Now, however, an international team of archaeologists is searching for the wreckage of the lost fleets. They may have found the first clue in an anchor with a well-preserved wooden stock. Wood samples from the stock were sent to two different laboratories, and their testing suggests the samples came from a tree felled between 1417 and 1530, the general time period of the conquest of Mexico. The wood of the stock may also be a type of red oak indigenous to northern Spain.
