The Battle of Bloody Marsh took place on 7 July 1742 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.

James Oglethorpe led the colonization of Georgia for Great Britain and had chosen Savannah as the principal port for the new colony. In the 1730s, Spain and Great Britain were disputing control of the border between Georgia and La Florida, where the Spanish had several settlements and forts. Given a heightened threat of Spanish invasion, Oglethorpe sought to increase his southern defenses. Accompanied by rangers and two Native American guides, Oglethorpe picked St. Simons Island as the site for a new town and fort. In 1734, Oglethorpe convinced the Parliament and the colonial trustees to pay for a military garrison at the fort.

The trustees also recruited a large group of colonists to settle St. Simons Island. The ships bearing the settlers and supplies arrived at Tybee Island early in 1736. From there, some went to the mainland while others traveled via periaguas (also known as pirogues) to St. Simons Island to found Frederica. The town and its fort were built on the elbow of the Frederica River to control approaches from both directions.

In 1737, Oglethorpe returned to England to acquire more funding and permission to raise a regiment of soldiers; he gained Parliamentary approval for both. He was appointed commander-in-chief of all British forces (limited as they were) in the colonies of South Carolina and Georgia. Oglethorpe subsequently recruited a company of Scots from Inverness, to migrate with their families to settle at Darien (briefly named "New Inverness") on the mainland, at the mouth of the Altamaha River.^[3] The men formed a military unit known locally as the Highland Independent Company. Official British records list it as Oglethorpe's Regiment of Foot. It was ranked as 42nd Regiment of Foot (old) in 1747 and disbanded 29 May 1749.^[4] Two forts had been constructed about five miles apart on St. Simons Island. Between the two ran a road the width of one wagon, named Military Road. This served to supply the garrison at Fort Frederica and settlers in the nearby village from Fort St. Simons.

The battles took place after a Spanish invasion of the island. They were part of the larger conflict known as the War of Jenkins' Ear (1739 to 1748). It derived its name from an incident in 1731. A Spanish boarding party had gone aboard a British brig Rebecca, off the Florida coast, and found that its captain Robert Jenkins was smuggling. The Spanish officer cut off one of Jenkins' ears for piracy. Parliament used the nearly forgotten incident to rally public opinion to their side in 1739, but the war was over trade and territorial competition between Britain and Spain. On October 30, 1739, Great Britain declared war on Spain.

Spanish governor Don Manuel de Montiano commanded the invasion force, which by some estimates totaled between 4,500 and 5,000 men. Of that number, roughly 1,900 to 2,000 were ground assault troops. Oglethorpe's forces, consisting of regulars, militia, and native Indians, numbered fewer than 1,000. The garrison at Fort St. Simons resisted the invasion with cannonade but could not prevent the landing.

On the 5 July 1742, Montiano landed nearly 1,900 men from 36 ships near Gascoigne Bluff, close to the Frederica River. Faced with a superior force, Oglethorpe decided to withdraw from Fort St. Simons before the Spanish could mount an assault. He ordered the small garrison to spike the guns and slight the fort (doing what damage they could), to deny the Spanish full use of the military asset. The Spanish took over the remains of the fort the following day, establishing it as their base on the island.

After landing troops and supplies, and consolidating their position at Fort St. Simons, the Spanish began to reconnoiter beyond their perimeter. They found the road between Fort St. Simons and Fort Frederica but assumed the narrow track was just a farm road. On 7 July the Spanish undertook a reconnaissance in force along the road with approximately 115 men under the command of Captain Sebastian Sanchez. Near Fort Frederica, Sanchez' column made contact with Oglethorpe's soldiers, under command of Noble Jones. The British routed the Spanish, killing or capturing nearly a third of their soldiers. Oglethorpe's forces advanced along Military Road toward Fort St. Simons in pursuit of the retreating Spanish. When Spanish prisoners revealed that a larger Spanish force was advancing from the opposite direction toward Frederica, Oglethorpe left to gather reinforcements.

The British advance party, in pursuit of the defeated Spanish force, engaged in a skirmish, then fell back in face of advancing Spanish reinforcements. When the British reached a bend in the road, lieutenants Southerland and Macoy ordered the column to stop. They took cover in a semi-circle-shaped area around a clearing behind trees and palmettos, waiting for the advancing Spanish having to take cover in the dense forest. They watched as the Spanish came into view through the marshy area. Once they were within range, the British fired multiple volleys from behind the protection of the dense forest. Fortunately for both sides, at this point it was later in the afternoon and it started to rain, causing the smoke from the muskets to hang in the air. Half of the British broke rank from not knowing where the Spanish muskets were firing from. General Oglethorpe left the battlefield to get more reinforcements, leaving his men without their commander. The Spanish did not take advantage of their numerical advantage and kept up their fire until they ran out of ammunition after an hour. Once out of ammo, they retreated back towards Fort St. Simons.

The attack killed seven Spaniards and a few British soldiers.^[5][6][7] The fighting at Bloody Marsh was filled with confusion on both sides. Neither side had a clear view of the strength or position of the other. Since the Spanish left the field of battle before the British, it was declared a victory for Oglethorpe and his men. The battle took its name from the British tradition that the marsh ran red with the blood of dead Spanish soldiers. However, the Spanish reports write they only lost seven men during the hour-long engagement. The battle blunted the Spanish advance and ultimately proved decisive. Oglethorpe was credited with the victory, though he arrived at the scene after the fighting had ceased.^[8]

Oglethorpe continued to press the Spanish, trying to dislodge them from the island. A few days later, approaching a Spanish settlement on the south side, he learned of a French man who had deserted the British and gone to the Spanish. Worried that the deserter might report how small the British force was, Oglethorpe spread out his drummers, to make them sound as if they were accompanying a larger force. He wrote to the deserter, addressing him as if he were a spy for the British, saying that the man just needed to continue his stories until Britain could send more men. The prisoner who was carrying the letter took it to the Spanish officers, as Oglethorpe had hoped, and the Spanish promptly executed the Frenchman. The timely arrival of British ships reinforced a misconception among the Spanish that British reinforcements were arriving. The Spanish left St. Simons on 25 July, ending their last invasion of colonial Georgia.^{[9][10][11][12]}

In the ensuing months, Oglethorpe considered counterattacks against Florida, but circumstances were not favourable. The focus of the war had shifted from the Americas to Europe; arms, supplies and troops were not readily available. The region settled into an uneasy peace, occasionally punctuated by minor skirmishes. Oglethorpe was later appointed brigadier general. About 1744 he left Georgia for Britain, where he married an heiress; he lived in Britain the rest of his life. The Treaty of Aix-la-Chapelle ended the war in 1748 and recognised the status of Georgia as a British colony, formally ratified by Spain in the subsequent Treaty of Madrid. Its position was further secured in 1763 when Spain ceded Florida to Britain in an exchange of territory under the Treaty of Paris ending the Seven Years' War.
