Cause

As part of James Oglethorpe's broader campaign to capture St. Augustine, British forces under Colonel John Palmer seized Fort Mose from Spain. The fort was a strategically important position in Spanish Florida, and its loss prompted Spanish commanders to organize an immediate counteroffensive to retake it.

Event

On June 14, 1740, Captain Antonio Salgado led approximately 300 Spanish regulars, joined by Francisco Menéndez's free black militia and Seminole warriors, in a surprise assault on Fort Mose. The 170-man British garrison was caught off guard and virtually annihilated. Colonel Palmer, three captains, and three lieutenants were killed in the fighting.

Consequence

The Spanish victory at Fort Mose effectively destroyed the British garrison and the fort itself, halting Oglethorpe's offensive against St. Augustine. Britain lost a key forward position in Florida, and the Spanish did not rebuild Fort Mose until 1752. The battle marked a decisive check on British expansion into Spanish colonial territory.
