The Battle of Olustee or Battle of Ocean Pond, was fought in Baker County, Florida, on February 20, 1864, during the American Civil War. It was the largest battle fought in Florida during the war.
Union General Truman Seymour had landed troops at Jacksonville and aimed chiefly to disrupt the Confederate food supply. Meeting little resistance, he proceeded towards the state capital, Tallahassee, against orders since he assumed that he would face only the small Florida militia. Confederates in Charleston sent reinforcements under General Alfred H. Colquitt, and the two armies collided near Ocean Pond in Olustee.
The Union forces were repulsed and retreated to Jacksonville. Some were garrisoned there to occupy territory.
