The struggle for control of the Mississippi River was the longest and most complex campaign of the Civil War. It was marked by an extraordinary diversity of military and naval operations, including fleet engagements, cavalry raids, amphibious landings, pitched battles, and the two longest sieges in American history. Every existing type of naval vessel, from sailing ship to armored ram, played a role, and military engineers practiced their art on a scale never before witnessed in modern warfare. Union commanders such as Grant, Sherman, Farragut, and Porter demonstrated the skills that would take them to the highest levels of command. When the immense contest finally reached its climax at Vicksburg and Port Hudson in the summer of 1863, the Confederacy suffered a blow from which it never recovered. Here was the true turning point of the Civil War. This fast-paced, gripping narrative of the Civil War struggle for the Mississippi River is the first comprehensive single-volume account to appear in over a century. Vicksburg Is the Key: The Struggle for the Mississippi River tells the story of the series of campaigns the Union conducted on land and water to conquer Vicksburg and of the many efforts by the Confederates to break the siege of the fortress. William L. Shea and Terrence J. Winschel present the unfolding drama of the campaign in a clear and readable style, correct historic myths along the way, and examine the profound strategic effects of the eventual Union victory.
