Fort Cooper (Inverness, Citrus County, Florida)
Inverness, Citrus County · Florida · Second Seminole War

History & Significance
Fort Cooper stands as a critical episode in the Second Seminole War (1835–1842), one of the costliest conflicts waged by the United States against Native Americans. In March 1836, General Winfield Scott left Major Mark Anthony Cooper with approximately 380 soldiers and volunteers of the First Georgia Battalion to establish a fortified post on Lake Holathlikaha in what is now Citrus County.
The wooden palisade fort, hastily constructed on a rise overlooking the lake, housed soldiers recovering from illness and combat wounds while Scott continued toward Fort Brooke. Beginning on the third day of the occupation, Seminole forces led by Osceola maintained a relentless siege for sixteen days, at one point attacking with more than 500 warriors.
Trapped within their fortification, the American defenders faced critical supply shortages, eventually slaughtering horses for food. Through vigilant leadership, Major Cooper held his position until relief arrived on April 18, sustaining approximately 20 wounded and only one killed.
The fort's successful defense demonstrated American military capacity to maintain a foothold in the Cove of the Withlacoochee, the Seminoles' principal stronghold, compelling their strategic retreat deeper into Florida. Subsequently, the post served as a reconnaissance, observation, and dispatch station until the war's end in 1842. Today, Fort Cooper State Park preserves the 710-acre site with reconstructed fortification elements and interpretive trails honoring both the soldiers and Seminole warriors whose struggle shaped Florida's history.
