Battle of Pocotaligo. Almost 5,000 Union troops, under Gen. Ormsby McKnight Mitchel, sail up the Broad River, aiming to cut the railroad that connects Charleston and Savannah, allowing them to threaten either city. The Union troops initially drive back outnumbered Confederate troops under Col. William S. Walker at Pocotaligo and take Coosawhatchie. However, when Confederate reinforcements arrive, the Union troops withdraw. Soon after, Mitchel dies of yellow fever at Beaufort. However, throughout the rest of the war, Union troops will attempt to cut the Charleston-to-Savannah railroad.
