The Battle of Baton Rouge was a brief

Spanish arms during Bernardo de Gálvez's march into West Florida

.

Background

Spanish Louisiana received word of this on July 21, he immediately began to plan offensive operations to take West Florida.^[3]

On August 27, Gálvez set out by land toward Fort Bute, leading a force that consisted of 520 regulars, of whom about two-thirds were recent recruits, 60 militiamen, 80 free blacks and mulattoes, and ten American volunteers headed by Oliver Pollock.^[4] As they marched upriver, the force grew by another 600 men, including Indians and Acadians. At its peak, the force numbered over 1,400, but this number was reduced due to the hardships of the march by several hundred before they reached the fort.^[5]

At dawn on September 7, this force attacked Fort Bute, a decaying relic of the French and Indian War that was defended by a small force.^[6] After a brief skirmish in which one German was killed, the garrison surrendered.^[5] The six who escaped capture made their way to Baton Rouge to notify the British troops there of the fort's capture.^[7]

After several days' rest, Gálvez advanced on Baton Rouge, only 15 miles (24 km) from Fort Bute.

60th Regiments, as well as some artillerymen, and several companies of Germans from the 3rd Waldeck Regiment.^[8]

British defenses

Dickson had decided weeks earlier that

chevaux de frise on the outside. It was surrounded by a moat 18 feet (5.5 m) wide and 9 feet (2.7 m) deep, and fortified with thirteen cannons.^[10]

Battle

Gálvez first sent a detachment of men further up the river to break communications between Baton Rouge and British sites further upriver. Before the fort he was unable to directly advance his own artillery, so Gálvez ordered a feint to the north through a wooded area, sending a detachment of his poorly trained militia to create disturbances in the forest. The British turned and unleashed massed volleys at this body, but the Spanish forces, shielded by substantial foliage, suffered some casualties. This attack was eventually driven off. While this went on, Gálvez dug siege trenches and established secure gunpits within musket range of the fort. He placed his artillery pieces there, opening fire on the fort on September 21.^[8]

Later on the Spanish open up with heavy artillery on the british fort. The British endured many hours of heavy mortar shelling before Dickson was offered full military surrender. Gálvez demands included the capitulation of the (80 Grenadiers of the 60th Regiment Of Foote) at Fort Panmure (modern Natchez, Mississippi), a well-fortified position that would have been difficult for Gálvez to take militarily. Dickson surrendered 375 regular troops the next day; Gálvez had Dickson's militia disarmed and sent home. Gálvez then sent a detachment of 50 men to take control of Panmure.^[11] He also dismissed his own militia companies, left a sizable garrison at Baton Rouge, and returned to New Orleans with about 50 men.

Aftermath

Daughters of the American Revolution commemorative marker

When informed that Dickson had surrendered Fort Panmure, its commander was irate, believing Dickson had surrendered Panmure to get better terms of surrender. Isaac Johnson, a local justice of the peace, wrote that "In the mighty battle between Governor Gálvez and Colonel Dickson, the Spaniards only lost one man and some say not one, the English lost twenty-five and the commanding officer wounded his head on his tea table".^[12]

The victory at Baton Rouge cleared the

Waldecker troops and ten to twelve sailors by a sloop crewed by 14 native Louisianans.^[13]

Gálvez was promoted to brigadier general for his successful campaign, and his exploits were immortalized in the poetry of

Julien Poydras.^[14] He immediately began planning an expedition against Mobile and Pensacola, the remaining British strongholds in West Florida, which would culminate in the capture of Pensacola, the West Florida capital, in 1781.^[15]

Baton Rouge remained in Spanish hands for the rest of the war, and Britain ceded both West and East Florida to Spain in the 1783 Treaty of Paris. It would not become American territory until 1821.
