By 1864, long-term Union advantages in geography, manpower, industry, finance, political organization and transportation were overwhelming the Confederacy. Grant fought a number of bloody battles with Lee in Virginia in the summer of 1864. Lee's defensive tactics resulted in extremely high casualties for Grant's army, but Lee lost strategically overall as he could not replace his casualties and was forced to retreat into trenches around his capital, Richmond, Virginia. Meanwhile, William Tecumseh Sherman, the leader of the Union Military Division of the Mississippi, captured Atlanta, Georgia. Sherman's March to the Sea destroyed a hundred-mile-wide swath of Georgia. In 1865, the Confederacy collapsed after Lee surrendered to Grant at Appomattox Court House; all slaves in the Confederacy were freed by the Emancipation Proclamation. Slaves in the border states and Union controlled parts of the South were freed by state action or by the Thirteenth Amendment.
The full restoration of the Union was the work of a highly contentious postwar era known as Reconstruction. The war produced about 970,000 casualties (3% of the population), including approximately 620,000 soldier deaths—two-thirds by disease. The war accounted for more casualties than all other U.S. wars combined. The causes of the war, the reasons for its outcome, and even the name of the war itself are subjects of lingering controversy even today. The main results of the war were the restoration and strengthening of the Union (mainly by permanently ending the issue of secession), and the end of slavery in the United States.
