what was the result of the battle of vicksburg
Siege of Vicksburg The successful ending of the Vicksburg Campaign significantly degraded the ability of the Confederacy to maintain its war effort, as described in the Aftermath section of the campaign article. Some historians—e.g., Ballard, p. 308—suggest that the decisive battle in the campaign was actually the Battle of Champion Hill, which, once won by Grant, made victory in the subsequent siege a foregone conclusion. This action (combined with the surrender of Port Hudson to Maj. Gen. Nathaniel P. Banks on July 9) yielded command of the Mississippi River to the Union forces, who would hold it for the rest of the conflict.
