Maps from http://www.lib.utexas.edu/maps/ Public Domain (see http://navalhistory.flixco.info/H/118421x19817/8330/a0.htm)

According to the University of Texas, "most of the maps scanned by the University of Texas Libraries and served from this web site are in the public domain. No permissions are needed to copy them. You may download them and use them as you wish. A few maps are copyrighted, and are clearly marked as such.". As the image, when downloaded from here was no tagged, the map is PD.

Insofar the battle annotation make this necessary, I put this image in the public domain as well.
