Following the disaster in May 1863 at Chancellorsville, the 17th Connecticut Volunteer Infantry marched northwards with the rest of the Army of the Potomac. Now under General George Meade, the regiment faced it’s second test in battle. Finding itself once more on the exposed and isolated right flank of the army, the regiment’s second Lt. Colonel, Douglas Fowler, was also killed in action. Several resources can be found here, including, the official report (once again) by Major Allen Brady, casualty list, a contemporary account by James Montgomery Bailey (Company C) of the battle and his subsequent experience as a prisoner of war, a modern photo tour of the route of the 17th Connecticut leading from Emmitsburg, Maryland to Gettysburg, and an excellent presentation from Carolyn Ivanoff on the experiences of 3 members of the regiment.
For more information on the role of the regiment in the battle, read Connecticut Yankees at Gettysburg by Charles Hamblin [Ed. by Walter L. Powell]. Kent, OH: Kent State UP, 1993.
For more about the Seventeenth Connecticut at East Cemetery Hill, read The Hour Was One of Horror – East Cemetery Hill at Gettysburg by John M. Archer. Gettysburg, PA: Thomas Publications, 1997. I also highly recommend “The 17th Connecticut and 41st New York: A Revisionist History of the Defense of East Cemetery Hill” by James A. Woods. This was published in Issue 28 of the Gettysburg Magazine and it is a thought-provoking look at where the regiment was located (and it is not where the monument stands!).
