After about half an hour, the infantry support promised to the Union batteries hurried into position on Henry Hill. Under the command of Noah Farnham and accompanied by Chief of Artillery William Barry, the 11th New York “Fire Zouves”, numbering about 500 and armed with M1855 .58 caliber rifle-muskets, led the column taking up a position on the down slope immediately behind Ricketts’ guns. Two companies were held in reserve. Albert V. Colburn’s cavalry squadron followed later as “additional support.” Following the 11th New York was the 14th Brooklyn, but, for unknown reasons, remained back at the junction of the Sudley Road and Warrenton Turnpike near the Stone House. This allowed the U.S. Marine Battalion and the 1st Minnesota to move to the front. The Marines moved up the hill and sat down in column to the left of the New Yorkers, behind Griffin’s guns while the 1st Minnesota took position considerably to the right of the 11th, bordering the woods on the south edge of the Henry Farm. Up to that point, all that the Confederates could see were the 11 Union guns.
