<P> In January 1863 , McClernand and Sherman 's combined XIII and XV corps , the Army of the Mississippi , defeated the Confederates at Arkansas Post . Grant made five attempts to capture Vicksburg by water routes ; however , all failed . With the Union impatient for a victory , in March 1863 , the second stage to capture Vicksburg began . Grant marched his troops down the west side of the Mississippi River and crossed over at Bruinsburg . Adm. David D. Porter 's navy ships had previously made a run past Vicksburg 's batteries on April 16 , 1863 , enabling Union troops to be transported to the east side of the river . The crossing succeeded due to Grant 's elaborate series of demonstrations and diversions that masked his intended movements from the Confederates . After the crossing , Grant maneuvered his army inland , and after a series of battles , the state capital , Jackson , Mississippi , was captured . Confederate general John C. Pemberton was defeated by Grant 's forces at the battles of Champion Hill and of Black River Bridge and retreated to the Vicksburg fortress . After two unsuccessful and costly assaults on Vicksburg , Grant settled in for a 40 - day siege . Pemberton , unable to combine forces with the army of Joseph E. Johnson , which was hovering in central Mississippi , finally surrendered Vicksburg on July 4 , 1863 . The capture of Vicksburg was a turning point for the Union war effort . The surrender of Vicksburg and the defeat of Confederate general Robert E. Lee at Gettysburg were stinging defeats for the Confederacy , now split in two by the Union 's domination of the Mississippi River . President Lincoln promoted Grant to the permanent rank of Major General in the Regular Army . Vicksburg marked the second surrender of a Confederate army ( the other being Buckner 's surrender to Grant the year before ) . During the Vicksburg siege , Grant dismissed McClernand for publishing to the press a congratulatory order that seemed to claim it was McClernand 's corps that was winning the campaign . McClernand appealed the dismissal to his personal friend , President Lincoln , but to no avail . Grant had ended the rivalry on his own terms . The Union army had captured considerable Confederate artillery , small arms , and ammunition . Total casualties , killed or wounded , for the final operation against Vicksburg that started on March 29 , 1863 were 10,142 for the Union and 9,091 for the Confederacy . </P>
