Passage: During the American Civil War, Jacksonville was a key supply point for hogs and cattle being shipped from Florida to aid the Confederate cause. The city was blockaded by Union forces, who gained control of the nearby Fort Clinch. Though no battles were fought in Jacksonville proper, the city changed hands several times between Union and Confederate forces. The Skirmish of the Brick Church in 1862 just outside Jacksonville proper resulted in the first Confederate victory in Florida. In February 1864 Union forces left Jacksonville and confronted a Confederate Army at the Battle of Olustee resulting in a Confederate victory. Union forces then retreated to Jacksonville and held the city for the remainder of the war. In March 1864 a Confederate cavalry confronted a Union expedition resulting in the Battle of Cedar Creek. Warfare and the long occupation left the city disrupted after the war.
Output:
Who did Jacksonville support with supplies during the Revolutionary war?
