Battle of Cold Harbor

Battle context

Cold Harbor was one of the final engagements of Grant's Overland Campaign in Virginia. The battle is defined above all by the frontal assault of June 3, in which Union forces suffered the majority of their approximately 12,700 casualties attacking Confederate fortified positions. Lee's army, roughly half the size of Grant's force, held its lines and inflicted disproportionate losses—around 5,287 Confederate casualties against more than twice that number on the Union side. The outcome intensified criticism of Grant's generalship and his willingness to absorb heavy losses. Despite the tactical repulse, the engagement did not halt the broader Union strategic effort; Grant subsequently shifted the Army of the Potomac toward Petersburg, continuing pressure on Lee's forces. Cold Harbor thus stands as a costly Union failure within a campaign that, despite its attrition, kept Lee's army on the strategic defensive.
