The Battle of Sullivan’s Island was won by the American (Patriot/Continental) forces defending Fort Sullivan, later renamed Fort Moultrie, against a British naval and land assault on June 28, 1776.

Key outcome

  • American troops under Colonel William Moultrie successfully repelled the British fleet commanded by Commodore Sir Peter Parker and troops under General Henry Clinton.
  • The British attack failed, and the engagement is remembered as a major early American victory in the Revolutionary War, boosting Patriot morale before the Declaration of Independence.

Why the Americans won

  • The palmetto-log and sand construction of Fort Sullivan absorbed British cannon fire, preventing catastrophic damage to the American defenses.
  • British plans to flank the fort were thwarted when several ships grounded on a sandbar, leaving the main attack exposed and ultimately forcing a withdrawal.

Quick historical context

  • The battle took place near Charleston, South Carolina, and protected the important port city from British capture in 1776.
  • The victory elevated Moultrie and his men to hero status, and South Carolina later adopted the palmetto as a key symbol, reflected in its state flag and identity.
