The City of Secrets · Mystery File 002 · Castillo de San Marcos

The Night an Entire City Disappeared

In 1702 about 1,500 people sheltered inside the Castillo for nearly two months while English forces besieged St. Augustine. The town burned. The fort held. Documented history

Imagine hearing that an army is marching toward your town, and you have only hours to decide what to carry.

In November 1702, forces from the English colony of Carolina, led by Governor James Moore, moved south against Spanish St. Augustine. It was part of a wider European conflict known in the colonies as Queen Anne's War.

The town had no walls strong enough to stop them. But it had the Castillo de San Marcos, finished only a few years earlier, in 1695. So the people of St. Augustine did something remarkable: around 1,500 residents, soldiers, families and enslaved and free people crowded inside the fortress and its moat.

Fifty days inside the walls

For nearly two months, the besiegers occupied the town and fired on the fort. Their cannon could not break the coquina walls, and they could not starve the defenders out before Spanish relief ships arrived from Havana. Late in December, Moore's forces retreated, burning their own ships and setting the town on fire as they left.

When the gates opened, the people inside had survived. Almost everything else had not. Houses, churches and records were gone. The St. Augustine you walk through today was rebuilt after this fire, which is one reason so few buildings are older than the early 1700s.

Why it matters

The siege proved what the fortress was for. It was not built to protect buildings. It was built to protect people. That lesson shaped the next fifty years of Spanish building in Florida.

Your mission

Stand on the open green outside the Castillo and imagine 1,500 people inside. Where would you put the cooking fires? Where would children sleep? How much water would everyone need each day?
