Within hours thousands of troops began to converge on the area, constructing fortifications that stretched from more than 7 miles. On June 3, Union forces under General Ulysses S. Grant attempted to break through the Confederate defenses in one of the most memorable frontal assaults of the war. These futile attacks produced thousands of casualties. Grant secretly moved his men toward Petersburg.
