The constant activity of the corps from May 5 till August 1 gave little opportunity for the various division and brigade commanders to record its work in detail; so there exists but meagre accounts of the numerous skirmishes and graver conflicts in which, in addition to the fights mentioned in this narrative, it engaged.  A detailed history of its performances is not within the province of a work of this nature; but in review, it can be said, without trespassing on the reader’s time, that the Cavalry Corps led the advance of the Army of the Potomac into the Wilderness in the memorable campaign of 1864; that on the expedition by way of Richmond to Haxall’s it marked out the army’s line of march to the North Anna; that it again led the advance to the Tolopotomy, and also to Cold Harbor, holding that important strategic point at great hazard; and that by the Trevillian expedition it drew away the enemy’s cavalry from the south side of the Chickahominy, and thereby assisted General Grant materially in successfully marching to the James River and Petersburg.  Subsequently, Wilson made his march to Staunton bridge, destroying railroads and supplies of inestimable value, and though this was neutralized by his disaster near Ream’s Station, the temporary set-back there to one division was soon redeemed by victory over the Confederate infantry at the battle of Darbytown.

In the campaign we were almost always on the march, night and day, often unable to care properly for our wounded, and obliged to bury our dead where they fell; and innumerable combats attest the part the cavalry played in Grant’s march from the Rapidan to Petersburg.  In nearly all of these our casualties were heavy, particularly so when, as was often the case, we had to engage the Confederate infantry; but the enemy returned such a full equivalent in dead and wounded in every instance, that finally his mounted power, which from the beginning of the war had been nurtured with a wise appreciation of its value, was utterly broken.

When the attempt to take Petersburg in conjunction with the mine explosion resulted in such a dismal failure, all the operations contemplated in connection with that project came to a standstill, and there was every prospect that the intensely hot and sultry weather would prevent further activity in the Army of the Potomac till a more propitious season.  Just now, however, the conditions existing in the Shenandoah Valley and along the upper Potomac demanded
