Confederates evacuate Battery Wagner and Morris Island

Strategic Context. Morris Island served as a strategic location in the outer reaches of Charleston Harbor, heavily fortified to defend the southern approaches. Battery Wagner, known as Fort Wagner to Union forces, was the center of these defenses. The island's position made it critical for controlling access to Charleston, leading to significant fighting during the Union campaign to capture the city.

Siege Conditions. Following the initial assaults in July, Union forces maintained constant bombardment for nearly 60 days. This sustained shelling caused severe damage to the fort's structure, leading to the burial of fallen soldiers within the walls. The proximity of Union siege trenches, combined with a lack of provisions, made the position increasingly untenable for the Confederate garrison.

Evacuation and Aftermath. The Confederate garrison abandoned Battery Wagner on the night of September 6–7, 1863, withdrawing all operable cannons and personnel. Following the evacuation, Union forces occupied Morris Island. The site subsequently saw further developments, including the use of Confederate prisoners as human shields in attempts to silence artillery at Fort Sumter.

Post-Evacuation Developments. After the Confederates abandoned Morris Island in 1863, the Union occupied it. In the next year, they transferred 600 Confederate officers from Fort Delaware to Morris Island, 50 of whom were quickly exchanged. The others were utilized as human shields in an attempt to silence the Confederate artillery at Fort Sumter.
