Florida's Fort under Six Flags
"I will take St. Augustine or leave my bones before its walls," claimed British General James Oglethorpe in 1740. He did neither. While he did raze part of the Florida city, he could not crack the Castillo de San Marcos and retreated from Spain's impenetrable fortress after a 38-day siege. The Castillo never fell to an enemy attack—only to international treaties.
