This is the story of the Civil War battle of Galveston Bay and what led up to it. It's the third book by Nagle about Civil War battles that took place west of the Mississippi, but the books don't need to be read in order. Each book is a stand-alone story. The book centers more on describing life during the War than on battles. Nagle only includes a couple of skirmishes and one real battle, but the stories of life in wartime are interesting.
