Gaines' Mill - June 27, 1862 - 3:30 to 4:00pm (December 2020)
American Battlefield Trust’s map of the Battle of Gaines’ Mill on June 27, 1862, from 3:30 to 4:00pm
Major General A. P. Hill's assault on the Federal position near Gaines' Mill grew in strength and intensity by 3:30 pm. As Hill's men descending one side of the Boatswain's Creek valley, they were subjected to smalls arms and artillery fire from the Union soldiers, who assumed a stong tree-line deep position overlooking the south bank of the creek. On Hill's right, the brigades of Generals Charles W. Field, James J. Archer, and Joseph R. Anderson were stopped by the Federals and then driven back. On Hill's left, he attempted to fill a gap between Maxy Gregg's South Carolina brigade and the rest of his division with the brigade of W. Dorsey Pender. A Federal counterattack by the brigades of Charles Lovell, Robert S. Buchannan, and Gouverneur K. Warren inflicted heavy casualties on Gregg's men, driving the Palmetto troops back toward New Cold Harbor. The ill-coordinated Confederate assault on the Federal V Corps line proved futile. Southern reinforcements and better coordination would be needed to dislodge Maj. Gen. Fitz John Porter and his men from their strong position along Boatswain's Creek.
