While Lincoln's funeral train was in New York City on April 24, Lieutenant Edward P. Doherty was dispatched from Washington at 2 p.m. with a detachment of 26 Union soldiers from the 16th New York Cavalry Regiment to capture Booth in Virginia, accompanied by Lieutenant Colonel Everton Conger, an intelligence officer assigned by Lafayette Baker. The detachment steamed down the Potomac River on the boat "John S. Ide", landing at Belle Plain, Virginia, at 10 pm. The pursuers crossed the Rappahannock River and tracked Booth and Herold to Richard H. Garrett's farm, about south of Port Royal, Virginia. Booth and Herold had been led to the farm on April 24 by William S. Jett, a former private in the 9th Virginia Cavalry, whom they had met before crossing the Rappahannock. The Garretts were unaware of Lincoln's assassination; Booth was introduced to them as "James W. Boyd", a Confederate soldier, they were told, who had been wounded in the battle of Petersburg and was returning home.
