The Battle of Fairfax Court House was the first land engagement of the American Civil War with fatal casualties. On June 1, 1861, a Union scouting party clashed with the local militia in Fairfax, Virginia, resulting in the war's first deaths in action, and the first wounding of a field-grade officer. The Union had sent a regular cavalry patrol under Lieutenant Charles H. Tompkins to estimate enemy numbers in the area. At Fairfax Court House, they surprised a small Confederate rifle company under Captain John Q. Marr, and took some prisoners. Marr rallied his unit, but was killed, and command was taken over by a civilian ex-governor of Virginia, William Smith, who forced the Union to retreat. The engagement is judged to have been inconclusive. The Union did not gain the intelligence it was seeking, and had to delay its drive on Richmond, thus enabling the Confederates to build up their strength at Manassas in advance of the much larger bigger battle there, the following month. Tompkins was criticized for exceeding his orders, although they had been somewhat imprecise.
