«Vicksburg» by James Reasoner

Vicksburg is the fifth in a ten-book series spanning the Civil War and describing its effects on one Southern family. In the waning months of 1862, as the Union army advances closer and closer, Cory Brannon must abandon the supply train to undertake a vital mission for Confederate General John Pemberton, the commander in charge of Vicksburg's defenses. The Federal bombardment, illness, injury, and starvation all take their toll on the defenders of Vicksburg, forcing Cory and Lucille to face decisions that threaten not only their love but also their lives.
