In consequence of the opening of the James River to the enemy's fleet, the attempts to utilize this channel for transportation, so as to approach directly to Richmond, soon followed. We had then no defenses on the James River below Drury's Bluff, about seven miles distant from Richmond. There an earthwork had been constructed and provided with an armament of four guns. Rifle-pits had been made in front of the fort, and obstructions had been placed in the river by driving piles, and sinking some vessels. The crew of the Virginia, after her destruction, had been sent to this fort, which was then in charge of Commander Farrand, Confederate States Navy.
On the 15th of April the enemy's fleet of five ships of war, among the number, their much-vaunted Monitor, took position and opened fire upon the fort between seven and eight o'clock. Our small vessel, the Patrick Henry, was lying above the obstruction, and coöperated with the fort in its defense—the Monitor and ironclad Galena steamed up to about six hundred yards' distance; the others, wooden vessels, were kept at long range.
The armor of the flag-ship Galena was badly injured, and many of the crew killed or wounded. The Monitor was struck repeatedly, but the shot only bent her plates. At about eleven o'clock the fleet abandoned the attack, returning discomfited whence they came. The commander of the Monitor, Lieutenant Jeffers, in his report, says that "the action was most gallantly fought against great odds, and with the usual effect against earthworks." . . . He adds, "It was impossible to reduce such works, except with the aid of a land force." The enemy in their reports recognized the efficiency of our fire by both artillery and riflemen, the sincerity of which was made manifest in the failure to renew the attempt.

The small garrison at Fort Drury, only adequate to the service it had performed, that of repelling an attempt by the fleet to pass up James River, was quite insufficient to prevent the enemy from landing below the fort, or to resist an attack by infantry. To guard against its sudden capture by such means, the garrison was increased by the addition of Bryan's regiment of Georgia Rifles.
After the repulse of the enemy's gunboats at Drury's Bluff, I wrote to General Johnston a letter to be handed to him by my aide, Colonel G. W. C. Lee, an officer of the highest intelligence and reputation— referring to him for full information in regard to the affair at Drury's Bluff, as well as to the positions and strength of our forces on the south side of the James River. After some speculations on the probable course of the enemy, and expressions of confidence, I informed the General that my aide would communicate freely to him and bring back to me any information with which he might be intrusted. Not receiving any definite reply, I soon thereafter rode out to visit General Johnston at his headquarters, and was surprised in the suburbs of Richmond, viz., on the other side of Gillis's Creek, to meet a portion of light artillery, and to learn that the whole army had crossed the Chickahominy.
General Johnston's explanation to this (to me) unexpected movement was, that he thought the water of the Chickahominy unhealthy, and had directed the troops to cross and halt at the first good water on the southern side, which he supposed would be found near to the river. He also adverted to the advantage of having the river in front rather than in the rear of him—an advantage certainly obvious enough, if the line was to be near to it on either of its banks.
The considerations which induced General McClellan to make his base on the York River had at least partly ceased to exist. From the corps for which he had so persistently applied, he had received the division which he most valued, and the destruction of the Virginia had left the James River open to his fleet and transports as far up as Drury's Bluff, and the withdrawal of General Johnston across the Chickahominy made it quite practicable for him to transfer his army to the James River, the south side of which had then but weak defenses, and thus by a short march to gain more than all the advantages which, at a later period of the war, General Grant obtained at the sacrifice of a hecatomb of soldiers.
Referring, again, to the work of the Comte de Paris, who may be better authority in regard to what occurred in the army of the enemy than when he writes about Confederate affairs, it appears that this change of base was considered and not adopted because of General McClellan's continued desire to have McDowell's corps with him. The Count states:
"The James River, which had been closed until then by the presence of the Virginia, as York River had been by the cannon of Yorktown, was opened by the destruction of that ship, just as York River had been by the evacuation of the Confederate fortress. But it was only open as far as Drury's Bluff; in order to overcome this last obstacle interposed between Richmond and the Federal gunboats, the support of the land forces was necessary. On the 19th of May Commodore Goldsborough had a conference with General McClellan regarding the means to be employed for removing that obstacle. . . . General McClellan, as we have stated above, might have continued to follow the railway line, and preserved his depots at Whitehouse, on the Pamunkey, . . . but he could also now go to reestablish his base of operations on James River, which the Virginia had hitherto prevented him from doing. By crossing the Chickahominy at Bottom's Bridge, and some other fords situated lower down, . . . could have reached the borders of the James in two or three days. . . . This flank march effected at a sufficient distance from the enemy, and covered by a few demonstrations along the upper Chickahominy, offered him great advantages without involving any risk. . . . If McClellan could have foreseen how deceptive were the promises of reënforcement made to him at the time, he would undoubtedly have declined the uncertain support of McDowell, to carry out the plan of campaign which offered the best chances of success with the troops which were absolutely at his disposal."
