Vicksburg: Control of the River

The Battle of Vicksburg was important because the Union’s victory on July 4, 1863 gave the North complete control of the Mississippi River, effectively splitting the Confederacy in half. This cut off Confederate states in the East from food and supplies produced in Texas and Arkansas, dealing a critical blow to the Southern war effort.

The Anaconda Plan was the Union’s strategy to strangle the Confederacy like a snake by blockading Southern ports, capturing the Mississippi River, and seizing the Confederate capital. The fall of Vicksburg fulfilled the second goal of the plan, cutting off the western Confederacy and severely limiting the South’s ability to continue fighting.

General Ulysses S. Grant besieged the city of Vicksburg, Mississippi for 47 days. With food and ammunition running out and no relief possible, Confederate General Pemberton surrendered his army of 30,000 soldiers on July 4, 1863, the same day Lee’s army began retreating from Gettysburg.

The battles of Vicksburg and Gettysburg both ended on the same day in July 1863, making that week the turning point of the Civil War. Gettysburg stopped Lee’s northern invasion in the East, while Vicksburg gave the Union control of the Mississippi River in the West, leaving the Confederacy in a losing position on both fronts.
