Excerpt from "The Enemy's Movements On The Stono River" article,

The Charleston Mercury, May 23, 1862

The evacuation of Coles' Island and Battery Island was entirely successful.  Everything was removed that was moveable, and Lt. T. G. Boag, of the Gist Artillery, who was in charge of the retreat from the last named island, proposed to take down the barracks, make a raft of the material, which is reported as scarce, and float it to a place of safety, but a 'military necessity' prevented this.  After the burning of the buildings, & c., a fire was kindled around the flag staff, and this too was consumed.

Letter to the Editor, "The Retreat From Battery Island"

The Charleston Mercury, May 27, 1862

To the Editor of the Charleston Mercury:

In your issue of the 23rd, your remarks headed "The Enemy's Movements on the Stono River," contain some errors, which I beg leave to correct.  While detracting nothing from the officers and members of the Gist Guards, who, in every respect, proved themselves worthy of the name they bear and the cause they are engaged in, I must, in duty to the Palmetto Guard Artillery, who were stationed on Battery Island proper, inform you that no company officer was in charge of the retreat from that Island, which was conducted under the direction of Colonel C. K. Huger; and also, that every building upon the Island was effectually fired by the regular guard of the day, detailed from the Palmetto Guard, who, in the discharge of this duty, remained for a considerable time after the departure of their company, and until ordered away by the commanding officer of the post.
