By order of Brigadier General Israel Vogdes (1816-1889) Col. Davis is to move his "entire Brigade with Camp Equipage & c. to Morris Island without delay." Order issued in the aftermath of the July 18, 1863, Battle of Fort Wagner during which Union forces failed to capture the fort, but the bravery of the 54th Massachusetts Infantry significantly boosted morale and demonstrated the heroism and fighting capabilities of African American soldiers.

After 60 days of shelling and siege, the Confederates abandoned Fort Wagner on September 7, 1863, just over a week after this order was given.
