The Battle of Bloody Marsh took place on July 18, 1742 (new style) between Spanish and British forces on St. Simons Island, part of the Province of Georgia, resulting in a victory for the British. Part of the War of Jenkins' Ear, the battle was for the British fortifications of Fort Frederica and Fort St. Simons, with the strategic goal the sea routes and inland waters they controlled. With the victory, the Province of Georgia established undisputed claim to the island. The British also won the Battle of Gully Hole Creek, which took place on the island the same day.
