While doing research I came across this document showing where a John Brown obtained 350 acres of land on Hog Island on the coast of South Carolina. This peaked my interest of where Hog Island was located?
Once known as Hog Island it is currently known as Patriots Point, Hog Island played a crucial role in the defense of the Charleston Harbor. In 1775, Patriot forces were sinking old ships in the deep Hog Island Channel to block British access to the Wando and Cooper Rivers. They were fired upon by British ships in the first naval battle of the Revolutionary as this helped promote the Patriot cause.
During the Civil War, mines were placed in the Hog Island Channel by the Confederates as a defense against Union ships. A Confederate gun battery on the tip of Hogs Island also protected the channel. The island was gradually connected to the mainland by dredge spoil. The area was annexed by Mount Pleasant in 1975 and was later developed and renamed Patriots Point.
