My estimate, made on the field, of the troops engaged was, Confederate, 9000; Union, 12,000. The casualties of the engagement were, Confederate, 1565 aggregate;[11] Federal, 2288 aggregate.[12]
General McClellan was at Yorktown during the greater part of the day to see Franklin’s, Sedgwick’s, and Richardson’s divisions aboard the transports for his proposed flanking and rear move up York River, but upon receiving reports that the engagement at Williamsburg was growing serious and not satisfactory, he rode to the battle, and called the divisions of Sedgwick and Richardson to follow him.
The object of the battle was to gain time to haul our trains to places of safety. The effect, besides, was to call two of the divisions from their flanking move to support the battle, and this so crippled that expedition that it gave us no serious trouble. The trophies of the battle were with the Confederates, and they claim the honor to inscribe Williamsburg upon their battle-flags.
The success of General Hancock in holding his position in and about the forts with five regiments and two batteries against the assault of the Fifth North Carolina and Twenty-fourth Virginia Regiments was given heroic proportions by his chief, who christened him “The Superb,” to relieve, it is supposed, by the picturesque figure on his right, the discomfiture of his left. But, reading between the lines, the highest compliment was for the two Confederate regiments.
In his official account, General Johnston said,—
“The action gradually increased in magnitude until about three o’clock, when General Longstreet, commanding the rear, requested that a part of Major-General Hill’s troops might be sent to his aid. Upon this I rode upon the field, but found myself compelled to be a spectator, for General Longstreet’s clear head and brave heart left no apology for interference.”
Franklin’s division was taken by transports to the mouth of Pamunkey River, and was supported by the navy. On the 7th a brigade of Sedgwick’s division joined Franklin. On the same day, Johnston’s army was collected near Barhamville. General Whiting, with Hood’s brigade and part of Hampton’s, engaged the advance of Franklin’s command and forced it back. This cleared our route of march towards Richmond, Smith’s and Magruder’s divisions by the road to New Kent Court-House, Hill’s and Longstreet’s nearer the Chickahominy.
General McClellan’s plans were laid according to strict rules of strategy, but he was not quick or forcible in handling his troops.
