Battle of Bloody Marsh

On St. Simons Island, within the Province of Georgia, Spanish and British troops clashed on July 18, 1742 (new style), and the British emerged victorious. This clash formed one episode of the War of Jenkins' Ear, with the two sides contesting control of Fort Frederica and Fort St. Simons, since whoever held these strongholds commanded the surrounding sea routes and inland waters. Thanks to this triumph, Georgia secured an unchallenged hold on the island. That same day, British forces also prevailed at the Battle of Gully Hole Creek, fought elsewhere on the same island.

Background

Great Britain's colonization effort in Georgia was directed by James Oglethorpe, who settled on Savannah as the colony's main port. During the 1730s, a dispute simmered between Spain and Great Britain over where the boundary lay between Georgia and La Florida, a region where Spanish forts and settlements were already established. Concerned that Spain might launch an invasion, Oglethorpe worked to strengthen his defenses in the south. With rangers and two Native American guides at his side, he selected St. Simons Island as the location for a fresh settlement and fortification. By 1734 he had persuaded both Parliament and the colonial trustees to fund a military garrison there.

Beyond securing that funding, the trustees also gathered a substantial number of colonists bound for St. Simons Island. Vessels carrying these settlers and their supplies reached Tybee Island in early 1736. Some continued on to the mainland from there, while others made their way by periagua, also called pirogue, toward St. Simons Island to establish Frederica. Builders situated the town and fort at the bend of the Frederica River so that approaches from either direction could be watched.

Oglethorpe sailed back to England in 1737 to secure further funds and authorization to form a regiment. Parliament granted both requests, and he was named commander of all British military forces, however limited, across South Carolina and Georgia. He then brought in a company of Scots from Inverness, who relocated with their families to Darien, a settlement briefly called "New Inverness" situated where the Altamaha River meets the sea. Locally, this unit became known as the Highland Independent Company, though British records officially designated it Oglethorpe's Regiment of Foot. It was later ranked as the 42nd Regiment of Foot (old) in 1747 before being disbanded on May 29, 1749. On St. Simons Island, two forts stood roughly five miles from one another, connected by a single wagon-wide path called Military Road, which allowed supplies to travel from Fort St. Simons to the garrison at Fort Frederica and to the settlers living in the village nearby.

What followed was a series of battles triggered by a Spanish invasion of the island, forming part of the broader War of Jenkins' Ear, which stretched from 1739 until 1748. That conflict's name traced back to an episode from 1731, when Spanish boarders searched the British brig Rebecca off the coast of Florida and discovered that its captain, Robert Jenkins, was engaged in smuggling. As punishment for piracy, the Spanish officer sliced off one of Jenkins' ears. Though the incident had faded from memory, Parliament revived it in 1739 to stir public sentiment, even though the true roots of the war lay in commercial and territorial rivalry between the two nations. Great Britain formally declared war on Spain on October 30, 1739.

Invasion, battle, and aftermath

Command of the Spanish invasion fell to governor Don Manuel de Montiano, who led a force estimated at 4,500 to 5,000 men, roughly 1,900 to 2,000 of whom were assigned to ground assault duties. By contrast, Oglethorpe could muster fewer than 1,000 men, drawing on regulars, militia, and native Indians. Cannon fire from the garrison at Fort St. Simons failed to stop the Spanish from coming ashore.

Montiano brought nearly 1,900 troops onto the beach near Gascoigne Bluff on 5 July 1742, using 36 ships to reach a spot close to the Frederica River. Recognizing that his own numbers could not match this force, Oglethorpe chose to pull his men out of Fort St. Simons rather than wait for a Spanish assault. Before leaving, he had the small garrison spike the cannons and damage the fort as much as possible, denying its full use to the enemy. By the next day, Spanish troops had claimed what remained of the fort and turned it into their island headquarters.

Once troops and supplies had come ashore and the position at Fort St. Simons was secure, Spanish scouts began probing the surrounding area. They came across the road linking Fort St. Simons to Fort Frederica, mistaking the narrow path for nothing more than a farm track. On 7 July, Captain Sebastian Sanchez led roughly 115 men on a reconnaissance mission along this route. His column encountered Oglethorpe's soldiers, commanded by Noble Jones, near Fort Frederica. The British scattered the Spanish troops, killing or seizing close to a third of them. As the Spanish retreated, Oglethorpe's men chased them down Military Road toward Fort St. Simons. Word from captured Spanish soldiers that another, larger force was approaching Frederica from the other side prompted Oglethorpe to depart in search of reinforcements.

Roughly 200 Spanish soldiers died in the fighting that followed. What happened at Bloody Marsh was brutal enough that the site earned its name from stories that Spanish blood turned the marsh red. Corpses and wounded men covered the forest floor. Spanish officers made a futile attempt to rally their troops, but panic sent the soldiers and their allies scattering in every direction as musket fire poured out from hidden positions in the brush, volley after volley. Barba suffered fatal wounds before being taken prisoner. This engagement stopped the Spanish push forward and proved to be the turning point of the campaign. Although he did not reach the battlefield until after the shooting stopped, Oglethorpe received credit for the win. Confusion reigned among both sides throughout the clash at Bloody Marsh.

Oglethorpe kept up the pressure on the Spanish, seeking to force them off the island entirely. Days later, while nearing a Spanish settlement on the southern side, he discovered that a French deserter from the British ranks had gone over to the Spanish. Concerned that this man might expose how few soldiers he actually commanded, Oglethorpe positioned his drummers at intervals to create the impression of a much larger force. He then composed a letter addressed to the deserter as though the man were secretly working for the British, instructing him to maintain his false reports until additional troops arrived from Britain. As planned, the prisoner entrusted with delivering this letter brought it straight to Spanish officers, who responded by executing the Frenchman without delay. British ships arriving at just the right moment reinforced Spanish fears that reinforcements were indeed on the way. By 25 July, Spanish forces had abandoned St. Simons entirely, bringing to a close their final attempt to invade colonial Georgia.

Over the following months, Oglethorpe weighed the possibility of striking back into Florida, though conditions did not favor such action. As the war's center of gravity moved from the Americas to Europe, troops, weapons, and supplies grew scarce. What followed was an uneasy calm, broken now and then by small skirmishes. Oglethorpe eventually received a promotion to brigadier general. Around 1744, he departed Georgia for Britain, where he wed an heiress and spent the remainder of his life. War's end came in 1748 with the Treaty of Aix-la-Chapelle, which confirmed Georgia's status as a British colony, a recognition Spain later made official through the Treaty of Madrid. Georgia's security was further strengthened
