Battle of Hanover Court House - Victory for Union Peninsula Campaign

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, for the Union reinforcements were recalled to Fredericksburg upon word of Maj. Gen. Nathaniel P. Banks's rout in the Shenandoah Valley at First Winchester.

Description: On May 27, 1862, elements of Brig. Gen. Fitz John Porter’s V Corps extended north to protect the right flank of McClellan’s Union army that now straddled the Chickahominy River. Porter’s objective was to cut the railroad and to open the Telegraph Road for Union reinforcements under Maj. Gen. Irvin McDowell that were marching south from Fredericksburg. Confederate forces, attempting to prevent this maneuver, were defeated just south of Hanover Courthouse after a stiff fight. The Union victory was moot, however, for McDowell’s reinforcements were recalled to Fredericksburg upon word of Banks’s rout at First Winchester.
