8th Regiment Illinois Volunteer Cavalry

The 8th Regiment Illinois Volunteer Cavalry was a cavalry regiment that served in the Union Army during the American Civil War. The regiment served the duration of the war, and was the only cavalry regiment to serve the entire war in the Army of the Potomac. They also aided in the hunt for John Wilkes Booth and served as President Lincoln's honor guard while he lay in state under the rotunda. Lincoln gave them the nickname of "Farnsworth's Abolitionist Regiment" when he watched them march past the White House.

Service
The regiment was commissioned on August 11, 1861 and was assembled for service in St. Charles, Illinois on September 18, 1861 at the site donated by Colonel Farnsworth called Camp Kane. They were sent out on July 17, 1865 in Chicago, Illinois.

Battle of Gettysburg
During the Gettysburg Campaign, the 8th Illinois Cavalry was in the division of Brig. Gen. John Buford. They deployed west of Gettysburg on June 30, 1863 under the command of Colonel William Gamble, and waited for oncoming Confederates, they arrived early the following morning. The first shot of the subsequent battle was fired by Lieutenant Marcellus E. Jones of Company E, who borrowed a carbine from Sergeant Levi Shafer and fired at an unidentified officer on a gray horse over a half-mile away. The 8th, along with the rest of the brigade, performed a fighting withdrawal towards McPherson's Ridge, delaying the Confederate division of Henry Heth for several hours and allowing the Union I Corps to arrive.

Two decades after the war ended, veterans of the regiment dedicated a monument to the 8th Illinois along the crest of McPherson's Ridge. Lt. Jones would also erect a monument in recognition of the first shot he fired on the location of the shot next to the Whistler's home just east of Marsh Creek on the Chambersburg Pike. The stone was quarried from Naperville limestone; Napperville was the hometown of Levi Shafer, the trooper whose carbine he borrowed to take the first shot.

Total strength and casualties
The regiment suffered a total of 250 fatalities, made up of seven officer and 68 enlisted men who were killed in action or died of their wounds and one officer and 174 enlisted men died of disease.
