Frazier, author of the award-winning Fire in the Cane Field, expands up his Louisiana Quadrille with the release of book two, Thunder Across the Swamp: The Fight for the Lower Mississippi, February-May 1863. The better known stories of the campaigns for Vicksburg and Port Hudson grow richer and more nuanced by taking a look at the fighting west of the river as part of a larger picture.
