The main settlement on
St. Simon's Island was Fort Frederica,
a town based on a grid pattern. The riverside fort
was for the most part a conventional square fort with bastions at each
corner, but there was also a
spur battery to place additional firepower on the river.
When relations with Spain became more strained in the late 1730s, city walls were built around the town. Now the original fort could perhaps function as a citadel - a fallback position in case the town was captured. The town walls were small by European standards, with a moat 10 feet wide, but the design was interesting in that the trace was an innovative one based on Vauban's Neuf Brisach. The bastions had blockhouses that although they were proof only against small arms perhaps served like cavaliers in a more heavily built work. The curtain walls between the bastions were indented to provide flanking fire along the length of the wall. |
This is the view from within the fort. The spur battery has been eroded away by the river, but it was equipped with 6-7 guns. |
The northeast bastion
is a good place to understand the city walls. The blockhouse
no longer exists, but its site is marked by wooden rails. The
blockhouse helped dominate the moat. Along the curtain, a firestep allowed infantry to load under cover then step up to fire. In front of the rampart was a palisade, then a moat between 6 and 8 feet deep followed by another palisade about 10 feet in height. Although effective against infantry, a determined enemy with artillery could capture the fort, making an active defense of the island the best course of action. |
