Treaty of Moultrie Creek

With the 1823 Treaty of Moultrie Creek, the U.S. Government granted 20 years of protection and care for the Indians who were then required to occupy certain reservation lands in what is now known as central Florida. The confrontation occurred when the promises outlined in this 1823 Treaty, the 1832 Paynes Landing, and 1833 Fort Gibson Treaties were broken. 

December of 1835

In December of 1835 Florida’s Seminoles, smoldering with resentment, frustration, anger, and finally full-blown hatred because they felt that they had been deceived, manipulated and that treaties had been broken with them, resorted to warfare against the military forces of the U.S. Government. 

December 28, 1836

Under the leadership of Chiefs Micanopy, Alligator, and Jumper, the Seminoles ambushed and massacred a detachment of U.S. Regulars commanded by Brevet Major Francis Dade as they were marching north from Fort Brooke (Tampa) to Fort King (Ocala). There were 108 men in the detachment, of which only 2 survived. On the same day, Osceola and his warriors attacked and killed U.S. Indian Agent Wiley Thompson at Fort King (Ocala).

 January 1, 1836

Shocked at the Seminole’s successes, President Andrew Jackson put his most experienced officer, Major General Winfield Scott, in charge of the war.  By the time Scott was ready to begin his campaign, he had over 5,000 men at his disposal. Scott had an ambitious plan to capture the Seminoles in a three-way vice grip and eliminate them from their stronghold known then and now as the Cove of the Withlacoochee. Over the course of the next few months, General  Scott and others led a large number of troops in pursuits of the Seminoles, which soon proved futile. In the meantime, the Seminoles struck throughout the state.

April 2, 1836

Major Mark Anthony Cooper commanded approximately 300-380 men. They included five companies of the First Georgia Volunteers, plus an artillery company of a few Regulars and a cannon. He was ordered to set up defenses, erect a block house and picketing, establish a post of observation and hold his position until relieved. The fortification was built on the west bluff of Lake Holathlikaha – an historic spring-fed lake used as a source of water and a site to camp dating back to the pre-Columbian era. Such relief was not forthcoming until April 18th. In the interim, under constant daily Indian attack, by Major Cooper’s order, alternate Companies “sallied forth” outside the picket “to detect and dispel Osceola and his warriors” who were attempting to get the battalion to fire its cannon and thereby expend its powder supply.

Major Cooper’s command held its position of defense and attack under heavy fire from the Indians during what turned out to be the longest single, continual battle of General Scott’s Second Seminole War Campaign. Due to Major Cooper’s vigilant leadership during the two week siege, the Georgia Battalion sustained about 20 men wounded with but one man lost, Coronet Zadoc Cook, of the Morgan Guards Company. In his report to the U.S. War Department concerning his Campaign, General Scott recorded that “Major Cooper’s command was the only command that sallied outside their breastworks to attack and drive the enemy”.

Fort Cooper was utilized as a reconnaissance, observation, and dispatch post until 1842 by various U.S. Army detachments directed by the U.S. War Department with “positive orders given to penetrate the strongholds of the Withlacoochee Cove to capture and destroy everything calculated to give strength or sustenance to the enemy”.

The Battle of Fort Cooper was of significant military importance. It impressed Chief Osceola (the most famous Seminole who lived in the Cove of the Withlacoochee) and tribal chiefs that the Cove of the Withlacoochee was not invincible or defensible from effective military tactics. Nevertheless, due to the continued inefficiency of the U.S. Command, it took almost six years of indecisive encounters before the Indians finally vacated the Cove area and joined their resistance down the Southern Florida peninsula.

The Seminole’s effort to expend the powder supply of Fort Cooper had failed. When the relief column arrived they found the garrison extremely short of provisions. The men had “subsisted for some time on two and a half ounces of meat per diem with flour in proportion” but they had ample gun powder supply remaining

The U.S. War Department and the Florida Command erroneously thought the War would be short. However, it lasted over seven years. In terms of lives lost and money expended the Seminole Wars were the costliest of all American Indian War conflicts.

Measurements of the Fort’s Walls:

South Wall                   213.25 feet with 326 recorded posts

West Wall                    201.8 feet with 132 recorded posts

North Wall                   255.9 feet with 177 recorded posts

East Wall                     223.1 feet with 16 recorded posts

Construction utilized small white pine and laurel oak logs 5-10 inches in diameter which were irregularly staggered to chink the gaps of the vertical picketing.
