February 20
Battle of Olustee Fought in Florida
Confederate forces under Brigadier General Joseph Finegan turned back a Union drive into northern Florida, handing the invaders their costliest defeat in the state and securing the interior for the remainder of the war.
Summary
During the American Civil War, Union forces sought to disrupt Confederate control in the Deep South and secure Florida's resources. On February 20, 1864, approximately 5,500 Union troops under Brigadier General Truman Seymour advanced toward Lake City and encountered entrenched Confederate forces of similar size led by Brigadier General Joseph Finegan near Olustee Station. The battle unfolded in pine woods over several hours as Union units attacked piecemeal against strong defensive positions. Confederate artillery and infantry fire inflicted heavy casualties, forcing a Union retreat after ammunition shortages threatened their lines. The engagement became the largest battle fought in Florida during the war and helped maintain Confederate dominance in the state's interior.
Context
Florida served as a vital supplier of beef, salt, and other provisions for the Confederacy, an importance that grew after the fall of Vicksburg cut off western sources. President Abraham Lincoln directed Major General Quincy A. Gillmore, commander of the Department of the South, to launch an expedition aimed at disrupting those supply lines, recruiting Black soldiers, and laying the groundwork for a loyal state government under the ten-percent reconstruction plan. Gillmore entrusted the operation to Brigadier General Truman Seymour, who landed troops at Jacksonville in early February 1864 and conducted successful raids that met little initial resistance.
What Happened
Acting against Gillmore’s explicit instructions not to advance deep into the state, Seymour pushed westward along the Florida, Atlantic and Gulf Central Railroad toward Lake City with roughly 5,500 men. Confederate commander Brigadier General Joseph Finegan, reinforced by troops dispatched from Charleston under Brigadier General Alfred H. Colquitt, positioned about 5,000 men in defensive lines near Olustee Station and Ocean Pond. On the afternoon of February 20 the opposing forces collided in open pine woods; Seymour, expecting only militia, fed his regiments into the fight piecemeal against entrenched artillery and infantry. The Union attacks were repeatedly repulsed by concentrated rifle and cannon fire.
Aftermath
By late afternoon Seymour ordered a retreat toward Jacksonville after his ammunition ran low and casualties mounted. Union losses totaled 1,861 men—203 killed, 1,152 wounded, and 506 missing—while Confederate casualties reached 946. Finegan did not pursue aggressively, allowing most Union troops to reach safety, though the 54th Massachusetts and other Black regiments helped cover the withdrawal and later rescued a stranded train carrying wounded soldiers.
Legacy
The victory boosted Confederate morale in a theater overshadowed by larger eastern campaigns and confirmed that Union forces could not easily penetrate Florida’s interior. The battle remains the largest fought in the state during the war; its site is preserved at Olustee Battlefield Historic State Park, where annual reenactments continue to draw participants and visitors interested in Florida’s Civil War role and the contributions of United States Colored Troops.
Why It Matters
The Confederate victory preserved control over key supply areas and boosted Southern morale in a theater often overshadowed by larger eastern campaigns. It demonstrated the challenges of Union expeditions into peripheral regions and influenced subsequent military priorities. Today the Olustee Battlefield Historic State Park preserves the site and educates visitors on Florida's Civil War role.
