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
