This is the official Order of Sailing of the fleet that assaulted Port Royal Sound, South Carolina in November, 1861. The source of the page may be jotted on one of the dozens of pages in a box, folder or notebook that comprise research that has been shuffled, reviewed and moved around over the decades.
The battle is a featured episode in my novel Shot Tower. Recent work on that chapter was apparently conducted while the page was upside down. Admiral DuPont’s flagship, Wabash, is at the right center. Some ships were circled because they could be found in the book Ships of the Civil War 1861-1865 by Kevin J. Dougherty, a fine and useful volume.
