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.
Sheridan passed through the outer defences of Richmond, and could, no doubt, have passed through the inner ones. But having no supports near he could not have remained. After caring for his wounded he struck for the James River below the city, to communicate with Butler and to rest his men and horses as well as to get food and forage for them.
He moved first between the Chickahominy and the James, but in the morning (the 12th) he was stopped by batteries at Mechanicsville. He then turned to cross to the north side of the Chickahominy by Meadow Bridge. He found this barred, and the defeated Confederate cavalry, reorganized, occupying the opposite side. The panic created by his first entrance within the outer works of Richmond having subsided troops were sent out to attack his rear.
He was now in a perilous position, one from which but few generals could have extricated themselves. The defences of Richmond, manned, were to the right, the Chickahominy was to the left with no bridge remaining and the opposite bank guarded, to the rear was a force from Richmond. This force was attacked and beaten by Wilson's and Gregg's divisions, while Sheridan turned to the left with the remaining division and hastily built a bridge over the Chickahominy under the fire of the enemy, forced a crossing and soon dispersed the Confederates he found there.
The enemy was held back from the stream by the fire of the troops not engaged in bridge building.
On the 13th Sheridan was at Bottom's Bridge, over the Chickahominy. On the 14th he crossed this stream and on that day went into camp on the James River at Haxall's Landing. He at once put himself into communication with General Butler, who directed all the supplies he wanted to be furnished.
Sheridan had left the Army of the Potomac at Spottsylvania, but did not know where either this or Lee's army was now. Great caution therefore had to be exercised in getting back. On the 17th, after resting his command for three days, he started on his return. He moved by the way of White House. The bridge over the Pamunkey had been burned by the enemy, but a new one was speedily improvised and the cavalry crossed over it. On the 22d he was at Aylett's on the Matapony, where he learned the position of the two armies. On the 24th he joined us on the march from North Anna to Cold Harbor, in the vicinity of Chesterfield.
Sheridan in this memorable raid passed entirely around Lee's army: encountered his cavalry in four engagements, and defeated them in all; recaptured four hundred Union prisoners and killed and captured many of the enemy; destroyed and used many supplies and munitions of war; destroyed miles of railroad and telegraph, and freed us from annoyance by the cavalry of the enemy for more than two weeks.
