path unobstructed till he reached the Monocacy, where Ricketts’s division of the Sixth Corps, and some raw troops that had been collected by General Lew Wallace, met and held the Confederates till the other reinforcements that had been ordered to the capital from Petersburg could be brought up.  Wallace contested the line of the Monocacy with obstinacy, but had to retire finally toward Baltimore.  The road was then open to Washington, and Early marched to the outskirts and began against the capital the demonstrations which were designed to divert the Army of the Potomac from its main purpose in front of Petersburg.

Early’s audacity in thus threatening Washington had caused some concern to the officials in the city, but as the movement was looked upon by General Grant as a mere foray which could have no decisive issue, the Administration was not much disturbed till the Confederates came in close proximity.  Then was repeated the alarm and consternation of two years before, fears for the safety of the capital being magnified by the confusion and discord existing among the different generals in Washington and Baltimore; and the imaginary dangers vanished only with the appearance of General Wright, who, with the Sixth Corps and one division of the Nineteenth Corps, pushed out to attack Early as soon as he could get his arriving troops in hand, but under circumstances that precluded celerity of movement; and as a consequence the Confederates escaped with little injury, retiring across the Potomac to Leesburg, unharassed save by some Union cavalry that had been sent out into Loudoun County by Hunter, who in the meantime had arrived at Harper’s Ferry by the Baltimore and Ohio railroad.  From Leesburg Early retired through Winchester toward Strasburg, but when the head of his column reached this place he found that he was being followed by General Crook with the combined troops of Hunter and Sigel only, Wright having returned to Washington under orders to rejoin Meade at Petersburg.  This reduction of the pursuing force tempting Early to resume the offensive, he attacked Crook at Kernstown, and succeeded in administering such a check as to necessitate this general’s retreat to Martinsburg, and finally to Harper’s Ferry.  Crook’s withdrawal restored to Early the line of the upper Potomac, so, recrossing this stream, he advanced again into Maryland, and sending McCausland on to Chambersburg, Pennsylvania, laid that town in ashes, leaving three thousand non-combatants without shelter or food.

When Early fell back from the vicinity of Washington toward Strasburg, General Grant believed that he would rejoin Lee, but later manoeuvres of the enemy indicated that Early had given up this idea, if he ever, entertained it, and intended to remain in the valley, since it would furnish Lee and himself with subsistence, and also afford renewed opportunities for threatening Washington.  Indeed, the possession of the Valley of the Shenandoah at this time was of vast importance
