- Eastern moat deterred mainland assault while allowing naval resupply
This crucial position enabled Union forces to maintain control of Pensacola Bay, effectively strangling Confederate maritime operations in the region and securing a critical base for Gulf Coast operations.
Union Garrison Stands Firm
When Florida seceded from the Union in January 1861, Lieutenant Adam J. Slemmer made vital strategic decisions that would shape Fort Pickens’ destiny. With only 51 soldiers and 30 sailors, he abandoned the less defensible Fort Barrancas, consolidated his forces at Pickens, and destroyed resources that could aid the Confederacy.
Despite multiple surrender demands from Confederate forces, garrison morale remained steadfast. You’ll find that this determination paid off when President Lincoln ordered reinforcements in April 1861, bringing Colonel Harvey Brown to assume command.
The 6th New York Infantry’s arrival in June further strengthened the Union’s position. This resolve was tested during the October 9th Confederate assault on Santa Rosa Island, but the garrison’s coordinated defense resulted in a decisive victory, cementing Fort Pickens’ status as an enduring Union stronghold in Confederate territory.
Repelling Confederate Forces
Under cover of darkness on October 9, 1861, Confederate Brigadier General Richard Anderson launched a bold assault against Fort Pickens, leading 1,000-1,200 troops in a surprise landing four miles east of the Union stronghold.
Confederate tactics initially succeeded in routing the 6th New York Volunteers at Camp Brown, but disorientation among sand dunes hindered their advance.
- Union forces countered fiercely, driving Confederates back in a running skirmish
- Fort Pickens’ artillery and gunboat threats forced the enemy to retreat
- The assault cost Anderson’s forces 87 casualties compared to 67 Union losses
- Union resilience prevailed as Confederate forces abandoned their objective
The failed attack exemplified Fort Pickens’ strategic significance as one of only four Southern forts remaining in Union control throughout the Civil War, despite repeated Confederate attempts to seize this crucial stronghold.
The Battle of Santa Rosa Island

The Battle of Santa Rosa Island erupted on October 9, 1861, as Brigadier General Richard Anderson led 1,200 Confederate troops in a daring nighttime raid against Union positions. The Confederate tactics involved landing four miles east of Fort Pickens and dividing into three columns before launching a surprise attack on Camp Brown, successfully routing the 6th New York Regiment.
