The fighting turned into a bloody stalemate as darkness fell and strong thunderstorms began to move in. The Land Merrimack bombarded the Union front, with some of its shells reaching as far to the rear as the field hospital. The final actions of the evening were by the Vermont Brigade, commanded by Colonel William T. H. Brooks, of Brig. Gen. William F. "Baldy" Smith's division. Attempting to hold the flank south of the Williamsburg Road, the Vermonters charged into the woods and were met with murderous fire, suffering more casualties of any brigade on the field that day. The brigade as a whole took 439 casualties; the 5th Vermont regiment, commanded by Lt. Col. Lewis A. Grant, lost nearly half of its men, 209 of 428.
