It was my purpose to accompany this work with detailed maps, of which I have many that would be appropriate; but the cost of engraving would be heavy, and I am aware that there is in course of preparation by the Engineer Department a series of war-maps, which will soon be issued, and which are far better than any I can offer. I therefore omit all, and believe that each reader can follow the incidents of the narrative by the usual maps found in every library.
