Battle of Hanover Court House - Aftermath

Aftermath

General McClellan claimed that Hanover Court House was yet another "glorious victory over superior numbers" and judged that it was "one of the handsomest things of the war." However, the reality of the outcome was that superior (Union) numbers won the day in a disorganized fight, characterized by misjudgments on both sides. The right flank of the Union army remained secure, although technically the Confederates at Peake's Crossing had not intended to threaten it. And McDowell's Corps did not need its roads kept clear because it never arrived—the defeat of Union forces at the First Battle of Winchester by Stonewall Jackson in the Shenandoah Valley caused the Lincoln administration to recall McDowell to Fredericksburg. The estimates of Union casualties vary, from 355 (62 killed, 233 wounded, 70 captured) to 397. The Confederates left 200 dead on the field and 730 were captured by Porter's cavalry.

A greater impact than the actual casualties, according to historian Stephen W. Sears, was the effect on McClellan's preparedness for the next major battle, at Seven Pines and Fair Oaks four days later. During the absence of Porter, McClellan was reluctant to move more of his troops south of the Chickahominy, making his left flank a more attractive target for Johnston.
