The Battle of Hanover Court House, also known as the Battle of Slash Church, took place on May 27, 1862, in Hanover County, Virginia, as part of the Peninsula Campaign of the American Civil War. On May 27, elements of Brig. Gen. Fitz John Porter's V Corps extended north to protect the right flank of Maj. Gen. George B. McClellan's Union Army of the Potomac. Porter's objective was to deal with a Confederate force near Hanover Court House, which threatened the avenue of approach for Union reinforcements that were marching south from Fredericksburg. The smaller Confederate force, under Colonel Lawrence O'Bryan Branch, was defeated at Peake's Crossing after a disorganized fight. The Union victory was moot, however, since the Union reinforcements were recalled to Fredericksburg upon word of Maj. Gen. Nathaniel P. Banks's rout in the Shenandoah Valley at the First Battle of Winchester.

The Battle of Haw's Shop or Enon Church was fought on May 28, 1864, in Hanover County, Virginia, as part of Union Lt. Gen. Ulysses S. Grant's Overland Campaign against Confederate Gen. Robert E. Lee's Army of Northern Virginia during the American Civil War. Grant abandoned the stalemate following the Battle of North Anna (May 23–26) by once again swinging widely around Lee's right flank, using the Pamunkey River to screen his movements to the southwest. Lee's army moved directly south and took up positions on the southern bank of Totopotomoy Creek. The Confederate general sent a cavalry force under Maj. Gen. Wade Hampton to collect intelligence about Grant's next moves. On May 28, Hampton's troopers encountered Union cavalry under Brig. Gen. David McM. Gregg. Fighting predominately dismounted and utilizing earthworks for protection, neither side achieved an advantage. Gregg was reinforced by two brigades of Brig. Gen. Alfred T.A. Torbert's division, and the brigade under Brig. Gen. George A. Custer launched a spirited attack just as Hampton was ordering his men to withdraw. The seven-hour battle was inconclusive, but it was the second significant cavalry engagement of the Overland Campaign and one of the bloodiest of the war. Both sides claimed victory. Union Cavalry Corps commander Maj. Gen. Philip Sheridan bragged that his men had driven Hampton from the field and demonstrated the superiority of the Union cavalry. But Hampton had held up the Union cavalry for seven hours, prevented it from achieving its reconnaissance objectives, and had provided valuable intelligence to General Lee about disposition of Grant's army.
