The Gulf Coast campaign or the Spanish conquest of West Florida in the

Bernardo de Gálvez, against the British province of West Florida. Begun with operations against British positions on the Mississippi River shortly after Britain and Spain went to war in 1779, Gálvez completed the conquest of West Florida in 1781 with the successful siege of Pensacola
.

Background

Spain officially entered the American Revolutionary War on May 8, 1779, with a formal declaration of war by King Charles III. This declaration was followed by another on 8 July that authorized his colonial subjects to engage in hostilities against the British.[1] When Bernardo de Gálvez, the colonial Governor of Spanish Louisiana, received word of this on 21 July, he immediately began to secretly plan offensive operations. Gálvez, who had been planning for the possibility of war since April, intercepted communications from the British at Pensacola indicating that the British were planning a surprise attack on New Orleans; he decided to launch his own attack first.[2] To that end, he concealed from the public his receipt of the second proclamation.[3]

Control of the lower Mississippi

On August 27, Gálvez set out by land toward Baton Rouge, leading a force that consisted of 520 regulars (about two-thirds of them recent recruits), 60 militiamen, 80

Anglo-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; this number was reduced due to the hardships of the march, by several hundred, before they reached Fort Bute.[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 token force.[6] After a brief skirmish in which one German was killed, most of 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 a few days' rest, Gálvez advanced on

Baton Rouge, only 15 miles (24 km) from Fort Bute.[6] When Gálvez arrived at Baton Rouge on 12 September, he found Fort New Richmond garrisoned by over 400 regular army troops and 150 militia, under the overall command of Lt. Colonel Alexander Dickson.[8] After nine days' siege
, Dickson surrendered.

Gálvez demanded and was granted terms that included the capitulation of the 80 Elite Grenadiers from the newly arrived 60th Regiment of Foote at Fort Panmure (modern Natchez, Mississippi), a well-fortified position which 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.[9] He dismissed his own militia companies, left a sizable garrison at Baton Rouge, and returned to New Orleans with about 50 men.
