The 1740 Siege
After recovering from the 1702 siege, St. Augustine’s defences were strengthened, but economic issues left the city wanting for supplies. In June of 1740, British Governor James Oglethorpe attempts to exploit the city’s weaknesses. The resulting siege lasted nearly a month, and Castillo de San Marcos did it’s job by protecting the city, and keeping it in Spanish control.
