Further description from Emilio ( [BBR], p.108):

…Orders came on the 26th that, owing to the few officers and lack of arms, the Fifty-fourth should only furnish fatigue details.

Quartermaster Ritchie, who was sent to Hilton Head, returned on the 29th with the officers, men, and camp equipage from St. Helena, and tents were put up the succeeding day. Some six hundred men were then present with the colors, including the sick. The number of sick in camp was very large, owing to the severe work and terrible heat. About nineteen hundred were reported on August 1 in the whole command. The sight of so many pale, enfeebled men about the hospitals and company streets was dispiriting. As an offset, some of those who had recovered from wounds returned, and Brig.-Gen. Edward A. Wild’s brigade of the First North Carolina and Fifty-fifth Massachusetts, both colored, arrived and camped on Folly Island.
