July 4
Confederate Forces Surrender at Vicksburg
Summary
After a 47-day siege, Confederate lieutenant general John C. Pemberton capitulated to Union major general Ulysses S. Grant on July 4, 1863, ending the Battle of Vicksburg. Grant's forces had encircled the Mississippi River stronghold in May, cutting off supplies and bombarding the city relentlessly. Pemberton's 30,000 troops marched out and stacked arms; many were paroled rather than imprisoned. The victory gave the Union complete control of the Mississippi River, splitting the Confederacy in two and fulfilling a key strategic objective outlined by President Lincoln. News of the surrender reached the North on July 4, coinciding with celebrations of Independence Day and boosting morale after earlier setbacks.
Why It Matters
Vicksburg's fall secured Union dominance of the Mississippi, isolating Texas, Arkansas, and Louisiana from the rest of the Confederacy and enabling further western campaigns. Grant's success elevated him to overall command of Union armies the following year. The date also cemented July 4 as a day of Union triumph in the western theater of the Civil War.
