CHAPTER VII.
SEVEN PINES, OR FAIR OAKS.
A New Line of Defence—Positions of the Confronting Armies—Fitz-John Porter—Terrific Storm on the Eve of Battle—General Johnston’s Orders to Longstreet, Smith, and Huger—Lack of Co-operation on the Confederate Side, and Ensuing Confusion—Fatalities among Confederate Officers—Kearny’s Action—Serious Wounding of General Johnston at the Close of the Battle—Summary and Analysis of Losses.
On the 9th of May the Confederate army was halted, its right near Long Bridge of the Chickahominy River; its left and cavalry extending towards the Pamunkey through New Kent Court-House. On the 11th the commander of the Confederate ram “Virginia” (“Merrimac”), finding the water of James River not sufficient to float her to the works near Richmond, scuttled and sank the ship where she lay.
On the 15th the Federal navy attacked our works at Chapin’s and Drury’s Bluffs, but found them too strong for water batteries. That attack suggested to General Johnston that he move nearer Richmond to be in position to lend the batteries assistance in case of need. He crossed the Chickahominy, his right wing at Long Bridge, his left by Bottom’s Bridge, and took position from Drury’s Bluff on his right, to the Mechanicsville turnpike, with his infantry, the cavalry extending on the left and front to the lower Rappahannock and Fredericksburg. The right wing, D. H. Hill’s and Longstreet’s divisions, under Longstreet, from James River to White Oak Swamp; the left under G. W. Smith. Smith’s division and Magruder’s command from White Oak Swamp, extending thence to the Mechanicsville pike, with Jackson a hundred miles away in the Shenandoah Valley.
After careful study of the works and armaments at Drury’s Bluff, I ventured the suggestion that we recross the Chickahominy at Mechanicsville and stand behind Beaver Dam Creek, prepared against McClellan’s right when he should be ready to march towards Richmond, and call him to relieve his flank before crossing the river.
Although the country between McClellan’s landing on the Pamunkey to the Chickahominy was free of all obstacles on the 15th of May, the head of his advance did not reach the banks of the latter river till the 21st. On the 16th he established his permanent depot at the White House, on the Pamunkey, and organized two provisional army corps,—the Fifth, of Fitz-John Porter’s division, and Sykes’s, under command of Porter; the Sixth, of Franklin’s and W. F. Smith’s divisions, under Franklin. On the 26th the York River Railroad as far as the bridge across the Chickahominy was repaired and in use. This, with other bridges, was speedily repaired, and new bridges ordered built at such points as should be found necessary to make free communication between the posts of the army.
On the 24th parties were advanced on the Williamsburg road as far as Seven Pines, where a spirited affair occurred between General Naglee’s forces and General Hatton’s brigade, the latter withdrawing a mile and a half on the Williamsburg road. At the same time two other parties of Federals were sent up the left bank, one under General Davidson, of the cavalry, with artillery and infantry supports, as far as Mechanicsville, where he encountered and dislodged a Confederate cavalry force under Colonel B. H. Robertson and occupied the position. The third party, under Colonel Woodbury, the Fourth Michigan Infantry and a squadron of the Second United States Cavalry, moved up to New Bridge, where the Fifth Louisiana, Colonel Hunt, of Semmes’s brigade, was on picket. Finding the bridge well guarded, a party, conducted by Lieutenant Bowen, Topographical Engineers, marched up the river, concealing their movements, crossed to the west bank, and, passing down, surprised the Fifth Louisiana, threw it into disorder, and gained position on the west side.
Pleased at these successes, General McClellan sent a sensational despatch to the President. His position thus masked, rested his right upon Beaver Dam Creek, a stream that flows from the height between the Chickahominy and Pamunkey Rivers south to its confluence with the former a few hundred yards below Mechanicsville Bridge. Its banks are scarped, about six feet high, and eight feet apart, making a strong natural ditch for defensive works.
On commanding ground south of the creek admirably planned field-works were soon constructed, which made that flank unassailable. Two miles out from the river the creek loses its value as a defensive line. From Beaver Dam the line was extended down the river to New Bridge, where it crossed and reached its left out to White Oak Swamp, and there found as defensible guard as the right at Beaver Dam Creek. The swamp is about a quarter of a mile wide at the left, and down to the Chickahominy studded with heavy forest-trees, always wet and boggy, but readily forded by infantry, and at places by cavalry.
