The results of the battle were lopsided. Union casualties were 773, of which 691 were captured. Confederate losses were 36 killed and wounded. Jackson's victory over the small Union force at Front Royal forced the main Union Army at Strasburg under Banks into abrupt retreat. Jackson deceived Banks into believing that the Confederate army was in the main Valley near Harrisonburg; instead he had marched swiftly north to New Market and crossed Massanutten via New Market Gap to Luray. The advance to Front Royal placed Jackson in position to move directly on Winchester, Virginia, in the rear of the Union army. On May 24, Banks retreated down the Valley Pike to Winchester, harassed by Confederate cavalry and artillery at Middletown and Newtown (Stephens City), setting the stage for the First Battle of Winchester the following day.
