On the evening of May 20–21, 1864, the Battle of Spotsylvania Court House ended after costing 18,000 Union and 12,000 Confederate casualties.
"Spotsylvania Court House was the second engagement of the Overland Campaign, a series of battles fought in Virginia during May and June 1864. Lt. Gen. Ulysses S. Grant, general-in-chief of all Union armies, directed the Army of the Potomac, commanded by Maj. Gen. George Meade, against Confederate general Robert E. Lee’s Army of Northern Virginia. Grant’s objectives were to pursue Lee, cripple his army, and capture the Confederate capital of Richmond. Success relied on a relentless pursuit of the enemy, so Grant instructed Meade, 'Wherever Lee goes, there you will go also.'"
