Before General Ulysses S. Grant could capture Richmond, he had to defeat the Confederates at the Battle of Cold Harbor in June 1864. This battle was part of his Overland Campaign, where he sought to engage and weaken Confederate forces led by General Robert E. Lee. Despite suffering heavy casualties, Grant continued his relentless pressure on Lee's army, ultimately leading to the Siege of Petersburg, which set the stage for the fall of Richmond.
