Butler was in position by the 6th of May and had begun intrenching, and on the 7th he sent out his cavalry from Suffolk to cut the Weldon Railroad. He also sent out detachments to destroy the railroad between Petersburg and Richmond, but no great success attended these latter efforts. He made no great effort to establish himself on that road and neglected to attack Petersburg, which was almost defenceless. About the 11th he advanced slowly until he reached the works at Drury's Bluff, about half way between Bermuda Hundred and Richmond. In the mean time Beauregard had been gathering reinforcements. On the 16th he attacked Butler with great vigor, and with such success as to limit very materially the further usefulness of the Army of the James as a distinct factor in the campaign. I afterward ordered a portion of it to join the Army of the Potomac, leaving a sufficient force with Butler to man his works, hold securely the footing he had already gained and maintain a threatening front toward the rear of the Confederate capital.
The position which General Butler had chosen between the two rivers, the James and Appomattox, was one of great natural strength, one where a large area of ground might be thoroughly inclosed by means of a single intrenched line, and that a very short one in comparison with the extent of territory which it thoroughly protected. His right was protected by the James River, his left by the Appomattox, and his rear by their junction—the two streams uniting near by. The bends of the two streams shortened the line that had been chosen for intrenchments, while it increased the area which the line inclosed.
Previous to ordering any troops from Butler I sent my chief engineer, General Barnard, from the Army of the Potomac to that of the James to inspect Butler's position and ascertain whether I could again safely make an order for General Butler's movement in co-operation with mine, now that I was getting so near Richmond; or, if I could not, whether his position was strong enough to justify me in withdrawing some of his troops and having them brought round by water to White House to join me and reinforce the Army of the Potomac. General Barnard reported the position very strong for defensive purposes, and that I could do the latter with great security; but that General Butler could not move from where he was, in co-operation, to produce any effect. He said that the general occupied a place between the James and Appomattox rivers which was of great strength, and where with an inferior force he could hold it for an indefinite length of time against a superior; but that he could do nothing offensively. I then asked him why Butler could not move out from his lines and push across the Richmond and Petersburg Railroad to the rear and on the south side of Richmond. He replied that it was impracticable, because the enemy had substantially the same line across the neck of land that General Butler had. He then took out his pencil and drew a sketch of the locality, remarking that the position was like a bottle and that Butler's line of intrenchments across the neck represented the cork; that the enemy had built an equally strong line immediately in front of him across the neck; and it was therefore as if Butler was in a bottle. He was perfectly safe against an attack; but, as Barnard expressed it, the enemy had corked the bottle and with a small force could hold the cork in its place. This struck me as being very expressive of his position, particularly when I saw the hasty sketch which General Barnard had drawn; and in making my subsequent report I used that expression without adding quotation marks, never thinking that anything had been said that would attract attention—as this did, very much to the annoyance, no doubt, of General Butler and, I know, very much to my own. I found afterwards that this was mentioned in the notes of General Badeau's book, which, when they were shown to me, I asked to have stricken out; yet it was retained there, though against my wishes.
I make this statement here because, although I have often made it before, it has never been in my power until now to place it where it will correct history; and I desire to rectify all injustice that I may have done to individuals, particularly to officers who were gallantly serving their country during the trying period of the war for the preservation of the Union. General Butler certainly gave his very earnest support to the war; and he gave his own best efforts personally to the suppression of the rebellion.
The further operations of the Army of the James can best be treated of in connection with those of the Army of the Potomac, the two being so intimately associated and connected as to be substantially one body in which the individuality of the supporting wing is merged.
Before giving the reader a summary of Sherman's great Atlanta campaign, which must conclude my description of the various co-operative movements preparatory to proceeding with that of the operations of the centre, I will briefly mention Sheridan's first raid upon Lee's communications which, though an incident of the operations on the main line and not specifically marked out in the original plan, attained in its brilliant execution and results all the proportions of an independent campaign. By thus anticipating, in point of time, I will be able to more perfectly observe the continuity of events occurring in my immediate front when I shall have undertaken to describe our advance from the Rapidan.
On the 8th of May, just after the battle of the Wilderness and when we were moving on Spottsylvania I directed Sheridan verbally to cut loose from the Army of the Potomac, pass around the left of Lee's army and attack his cavalry: to cut the two roads—one running west through Gordonsville, Charlottesville and Lynchburg, the other to Richmond, and, when compelled to do so for want of forage and rations, to move on to the James River and draw these from Butler's supplies. This move took him past the entire rear of Lee's army. These orders were also given in writing through Meade.
The object of this move was three-fold. First, if successfully executed, and it was, he would annoy the enemy by cutting his line of supplies and telegraphic communications, and destroy or get for his own use supplies in store in the rear and coming up. Second, he would draw the enemy's cavalry after him, and thus better protect our flanks, rear and trains than by remaining with the army. Third, his absence would save the trains drawing his forage and other supplies from Fredericksburg, which had now become our base. He started at daylight the next morning, and accomplished more than was expected. It was sixteen days before he got back to the Army of the Potomac.
The course Sheridan took was directly to Richmond. Before night Stuart, commanding the Confederate cavalry, came on to the rear of his command. But the advance kept on, crossed the North Anna, and at Beaver Dam, a station on the Virginia Central Railroad, recaptured four hundred Union prisoners on their way to Richmond, destroyed the road and used and destroyed a large amount of subsistence and medical stores.
Stuart, seeing that our cavalry was pushing towards Richmond, abandoned the pursuit on the morning of the 10th and, by a detour and an exhausting march, interposed between Sheridan and Richmond at Yellow Tavern, only about six miles north of the city. Sheridan destroyed the railroad and more supplies at Ashland, and on the 11th arrived in Stuart's front. A severe engagement ensued in which the losses were heavy on both sides, but the rebels were beaten, their leader mortally wounded, and some guns and many prisoners were captured.
