On June 28, 1776, colonial forces successfully repelled British troops in a pivotal battle fought on a barrier island near Charleston, South Carolina. The topography of the terrain played a decisive role in the outcome of the conflict.

The victory is largely attributed to the geographical features of the island. The marshy, sandy terrain, coupled with an impassable inlet, significantly hindered the advance and maneuvers of the British forces, providing a key defensive advantage to the colonists.
