In 1519, Hernán Cortés led a Spanish army to modern-day Mexico to conquer the Aztec Empire. Upon landfall, two leaders mutinied to return to Cuba at the order of the governor who had commissioned the fleet Cortés led. In response, Cortés scuttled his fleet to forestall any future mutiny by closing the sole path of retreat.
Against all odds, Cortés went on to defeat an opposing force of over 300,000 Aztecs, a few thousand Spaniards, superior military technology, an unforeseen smallpox outbreak, and shrewd political alliances ultimately prevailed.
