Longstreet's Scout
Henry Thomas Harrison


During the early morning hours of June 28, 1863, Union General George Gordon Meade was appointed commander of the Army of the Potomac while at his headquarters near Frederick, Md.
Later that same day, a spy brought news about the location of Meade's army to Chambersburg,
Pennsylvania, a distance of fifty miles, where CSA Generals Lee and Longstreet were headquartered.


Henry Thomas Harrison, a Confederate spy, supplied Generals Longstreet and Lee with details about the advancing Union army. Based solely on that information, Lee ordered his dispersed army to move immediately towards a small crossroads town in south-central Pennsylvania. Thus was the beginning of the historic three-day battle known as Gettysburg.

We can only imagine what might have happened if Harrison had failed in his mission but it is a fact that he did change the course of history.

The identity of General James Longstreet's famous scout, known only as "Harrison" remained a mystery for more than a century. However, in 1986 historian James O. Hall identified this elusive man.  Researching the Civil War records at the National Archives, Hall found conclusive evidence that Longstreet's scout was Secret Agent H. T. Harrison.  
Harrison had joined the Mississippi State Militia in the spring of 1861 as a private.   But in November of 1861 he was discharged and eventually became a spy for CSA Secretary of War James Seddon.  Harrison's service for Longstreet at Gettysburg has long been established history and Hall's research has identified him but there is more to the story.  The purpose of this website is to publish additional facts as they are uncovered. 

Colonel G. Moxley Sorrel, Longstreet's Chief of Staff, wrote in his book, Recollections of a Confederate Staff Officer, that Harrison provided valuable information regarding the whereabouts and intentions of Union forces under their new commander, General George Gordon Meade, prior to the battle of Gettysburg.

Harrison appeared at Longstreet's headquarters near Chambersburg, Pennsylvania on the night of June 28, 1863 with news that Federal forces centered around Frederick, Maryland and were on there way north.  At that moment Lee's army was dispersed over a wide area of south central Pennsylvania.  Based solely on the information from a spy, Lee directed  his army to converge near Gettysburg.  Harrison's news saved Lee from a potential disaster and thus altered the course of history.

Sorrel knew nothing about Harrison's identity and no one on Longstreet's staff even knew his first name.  Longstreet must have known because he obtained a photograph of Harrison for his published memoirs, From Manassas to Appomattox. But Longstreet continued to maintain his secrecy in this matter.

There are no extant letters of correspondence between Longstreet and Harrison in Longstreet's manuscript collections.  What we do have is Longstreet's recollections published in Century Magazine, the Philadelphia Times, and finally, in his book, From Manassas to Appomattox. As a tribute to Harrison's espionage, Longstreet wrote in an 1887 article for Century Magazine that Harrison provided him "with information more accurate than a force of cavalry could have secured."

Chronology of known H. T. Harrison Facts

The following is a high-level summary of known facts about Henry Thomas Harrison.  Cites are in brackets following each entry.

The author of this website is the great-grandson of Henry Thomas Harrison and has been researching H. T. Harrison for many years.  After the Civil War Harrison became estranged from his family and maintained his privacy for the rest of his life.  He made no attempt to exploit his colorful career as a secret agent for the Confederacy.  In his application for pension he only claimed to be a Confederate Veteran without mention of being a spy or scout for Longstreet.
Years of research uncovered when and where he died.  A tip from Ms. Cindy Buck-Thompson led to the discovery that Harrison was living in Covington, Kentucky after leaving Cincinnati in 1912.  Further research revealed that he was buried at Highland Cemetery, Fort Mitchell, Kentucky.  The Office of Veterans Affairs has provided a CSA headstone and it is now in place.
