I heard a couple of years ago that there were 1 or 2 Unnamed Confederate batteries on some of these islands. I was wondering if this was true or just an old tale.
According to this text, there were in fact Confederate batteries there.
Also, Generals Daniel H. Hill and (then Colonel) John T. Wilder describe the action there as follows in this article: https://www.hmdb.org/m.asp?m=84222.
