The 4th was engaged the day before - on Oct. 11 - at Brandy Station. For a good account of that fight take a look at the diary of Lt. Col. Thomas Carter, published as saddles, sabres and spurs by Walbrook Swank.
the troops involved n the 12th at Sulphur Springs were Rosser's Laurel brigade and some infantry.
