Union Assault at Cold Harbor Repulsed in Civil War
By spring 1864, Union General Ulysses S. Grant had launched his Overland Campaign to destroy Robert E. Lee's Army of Northern Virginia rather than merely capture Richmond. After inconclusive fighting at the Wilderness and Spotsylvania, Grant maneuvered southeast, seizing the Cold Harbor crossroads in late May. On June 3, Grant ordered a massive frontal assault by three corps against Lee's entrenched lines, which had been reinforced overnight with formidable earthworks and artillery. The attack collapsed within minutes under devastating Confederate fire, resulting in roughly 7,000 Union casualties in under an hour while Lee suffered far fewer. Grant later called the assault his greatest regret, yet the armies remained locked in position until mid-June.
