Of the several military engagements that took place at Milford (present-day Overall) during the War, the most significant occurred on September 22, 1864. This engagement is associated specifically with Union Maj. Gen. Philip Sheridan's victory over Confederate Maj. Gen. Jubal Early at Winchester on September 19, Early's retreat south up the Shenandoah Valley and Sheridan's pursuit, and Early's subsequent stand and defeat by Sheridan at Fisher's Hill on September 21.
Williams Carter Wickham first encountered Union cavalry of the 3d Division commanded by Brig. Gen. James H. Wilson (under Maj. Gen. Alfred T. A. Torbert) on September 20 near Front Royal. An engagement began near Crooked Run and the Front Royal Road that resulted in the Confederates being driven across the South Fork of the Shenandoah River. Wilson renewed his attacks on September 21, and part of his force succeeded in flanking the Confederates by crossing the river at Kendrick's and Richard's Fords. A running battle then ensued as the Confederates retreated up the valley (southward) toward Luray. They made two stands, and retreated from the first but held the second on the south bank of Gooney Run. An artillery duel then began that lasted well into the night. Later that evening, Wickham's troops withdrew and entrenched along the slopes immediately south of Milford, extending their lines from the river eastward to the steep slope in the vicinity of the present-day Shenandoah National Park boundary. The Southerners burned, or at least partially burned, the little bridge over Milford Run in their front Some accounts refer to the bridge as if it were present during the battle.
During the night, Brig. Gen. Wesley Merritt's cavalry reinforced Wilson, bringing total Union strength to two divisions, the First and Third, each composed of two brigades and supported by three to five batteries of artillery. Brig. Gen. George Armstrong Custer commanded the 1st Brigade consisting of one New York and four Michigan regiments of Merritt's 1st Division. After midnight, the Federals discovered Wickham's new position at Milford. The Union cavalry and horse artillery then moved southward and set up their guns (some of which were placed at the present-day location of Skymont).
Other actions occurred at or near Milford during the War. They included cavalry engagements on June 24, 1862, in early May 1864, and on October 25–26, 1864. In addition, Union and Confederate troops camped or bivouacked there at various times during the war.
