What was the significant outcome of the Battle of Vicksburg?

The significant outcome of the Battle of Vicksburg was that it gave the Union control of the Mississippi River. This victory, occurring from May 18 to July 4, 1863, was a pivotal moment in the Civil War as it effectively split the Confederacy in two and disrupted their supply lines. The control of the Mississippi River was crucial for the Union, allowing them to move troops and supplies more freely throughout the Western theater of the war.

Gaining Vicksburg not only hindered the Confederacy's ability to communicate and transport resources between its eastern and western regions, but it also was a significant morale booster for Union forces. This victory, combined with the Battle of Gettysburg which occurred around the same time, marked a turning point in the war in favor of the Union. The implications of controlling the Mississippi River would continue to shape military strategy and outcomes for the rest of the war.
