I gave Sheridan instructions to have Hunter, in case he should meet him about Charlottesville, join and return with him to the Army of the Potomac. Lee, hearing of Hunter's success in the valley, started Breckinridge out for its defence at once. Learning later of Sheridan's going with two divisions, he also sent Hampton with two divisions of cavalry, his own and Fitz-Hugh Lee's.

Sheridan moved to the north side of the North Anna to get out west, and learned of the movement of these troops to the south side of the same stream almost as soon as they had started. He pushed on to get to Trevilian Station to commence his destruction at that point. On the night of the 10th he bivouacked some six or seven miles east of Trevilian, while Fitz-Hugh Lee was the same night at Trevilian Station and Hampton but a few miles away.

During the night Hampton ordered an advance on Sheridan, hoping, no doubt, to surprise and very badly cripple him. Sheridan, however, by a counter move sent Custer on a rapid march to get between the two divisions of the enemy and into their rear. This he did successfully, so that at daylight, when the assault was made, the enemy found himself at the same time resisted in front and attacked in rear, and broke in some confusion. The losses were probably very light on both sides in killed and wounded, but Sheridan got away with some five hundred prisoners and sent them to City Point.

During that day, the 11th, Sheridan moved into Trevilian Station, and the following day proceeded to tear up the road east and west. There was considerable fighting during the whole of the day, but the work of destruction went on. In the meantime, at night, the enemy had taken possession of the crossing which Sheridan had proposed to take to go north when he left Trevilian. Sheridan learned, however, from some of the prisoners he had captured here, that General Hunter was about Lynchburg, and therefore that there was no use of his going on to Charlottesville with a view to meet him.

Sheridan started back during the night of the 12th, and made his way north and farther east, coming around by the north side of White House, and arriving there on the 21st. Here he found an abundance of forage for his animals, food for his men, and security while resting. He had been obliged to leave about ninety of his own men in the field-hospital which he had established near Trevilian, and these necessarily fell into the hands of the enemy.

White House up to this time had been a depot; but now that our troops were all on the James River, it was no longer wanted as a store of supplies. Sheridan was, therefore, directed to break it up; which he did on the 22d of June, bringing the garrison and an immense wagon train with him. All these were over the James River by the 26th of the month, and Sheridan ready to follow.

In the meantime Meade had sent Wilson's division on a raid to destroy the Weldon and South Side roads. Now that Sheridan was safe and Hampton free to return to Richmond with his cavalry, Wilson's position became precarious. Meade therefore, on the 27th, ordered Sheridan over the river to make a demonstration in favor of Wilson. Wilson got back, though not without severe loss, having struck both roads, but the damage done was soon repaired.

After these events comparative quiet reigned about Petersburg until late in July. The time, however, was spent in strengthening the intrenchments and making our position generally more secure against a sudden attack. In the meantime I had to look after other portions of my command, where things had not been going on so favorably, always, as I could have wished.

General Hunter who had been appointed to succeed Sigel in the Shenandoah Valley immediately took up the offensive. He met the enemy on the 5th of June at Piedmont, and defeated him. On the 8th he formed a junction with Crook and Averell at Staunton, from which place he moved direct on Lynchburg, via Lexington, which he reached and invested on the 16th. Up to this time he was very successful; and but for the difficulty of taking with him sufficient ordnance stores over so long a march, through a hostile country, he would, no doubt, have captured Lynchburg. The destruction of the enemy's supplies and manufactories had been very great. To meet this movement under General Hunter, General Lee sent Early with his corps, a part of which reached Lynchburg before Hunter. After some skirmishing on the 17th and 18th, General Hunter, owing to a want of ammunition to give battle, retired from before the place. Unfortunately, this want of ammunition left him no choice of route for his return but by the way of the Gauley and Kanawha rivers, thence up the Ohio River, returning to Harper's Ferry by way of the Baltimore and Ohio Railroad. A long time was consumed in making this movement. Meantime the valley was left open to Early's troops, and others in that quarter; and Washington also was uncovered. Early took advantage of this condition of affairs and moved on Washington.

In the absence of Hunter, General Lew Wallace, with headquarters at Baltimore, commanded the department in which the Shenandoah lay. His surplus of troops with which to move against the enemy was small in number. Most of these were raw and, consequently, very much inferior to our veterans and to the veterans which Early had with him; but the situation of Washington was precarious, and Wallace moved with commendable promptitude to meet the enemy at the Monocacy. He could hardly have expected to defeat him badly, but he hoped to cripple and delay him until Washington could be put into a state of preparation for his reception. I had previously ordered General Meade to send a division to Baltimore for the purpose of adding to the defences of Washington, and he had sent Ricketts's division of the 6th corps (Wright's), which arrived in Baltimore on the 8th of July. Finding that Wallace had gone to the front with his command, Ricketts immediately took the cars and followed him to the Monocacy with his entire division. They met the enemy and, as might have been expected, were defeated; but they succeeded in stopping him for the day on which the battle took place. The next morning Early started on his march to the capital of the Nation, arriving before it on the 11th.
