Civil War Trust’s map of the Battle of Cold Harbor
On May 31, Sheridan’s cavalry seized the vital crossroads of Old Cold Harbor. Early on June 1, relying heavily on their new repeating carbines and shallow entrenchments, Sheridan’s troopers threw back an attack by Confederate infantry. Confederate reinforcements arrived from Richmond and from the Totopotomoy Creek lines. Late on June 1, the Union Sixth and Eighteenth Corps reached Cold Harbor and assaulted the Confederate works with minimal success. By June 2, both armies were on the field, forming on a seven-mile front that extended from Bethesda Church to the Chickahominy River. At dawn June 3, the Second and Eighteenth Corps, followed later by the Ninth Corps, assaulted along the Bethesda Church-Cold Harbor line and were slaughtered at all points. Grant commented in his memoirs that this was the only attack he wished he had never ordered. The armies confronted each other on these lines until the night of June 12, when Grant again advanced by his left flank, marching to James River. On June 14, the Second Corps was ferried across the river at Wilcox’s Landing by transports. On June 15, the rest of the army began crossing on a 2,200-foot long pontoon bridge at Weyanoke. Abandoning the well-defended approaches to Richmond, Grant sought to shift his army quickly south of the river to threaten Petersburg.
