d-day men. Their
time will soon be out, but for the present they will do to serve in
the defenses.

"U. S. GRANT, Lieutenant-General."

The despatch explained the movement from Culpeper, and on the morning
of the 15th Merritt's two remaining brigades were sent to Front Royal
to oppose Anderson, and the Sixth Corps withdrawn to the north side
of Cedar Creek, where it would be in a position enabling me either to
confront Anderson or to act defensively, as desired by General Grant.

To meet the requirements of his instructions I examined the map of
the valley for a defensive line--a position where a smaller number of
troops could hold a larger number--for this information led me to
suppose that Early's force would greatly exceed mine when Anderson's
two divisions of infantry and Fitzhugh Lee's cavalry had joined him.
I could see but one such position, and that was at Halltown, in front
of Harper's Ferry. Subsequent experience convinced me that there was
no other really defensive line in the Shenandoah Valley, for at
almost any other point the open country and its peculiar topography
invites rather than forbids flanking operations.

This retrograde movement would also enable me to strengthen my
command by Grower's division of the Nineteenth Corps and Wilson's
cavalry, both of which divisions were marching from Washington by way
of Snicker's Gap.

After fully considering the matter, I determined to move back to
Halltown, carrying out, as I retired, my instructions to destroy all
the forage and subsistence the country afforded. So Emory was
ordered to retire to Winchester on the night of the 15th, and Wright
and Crook to follow through Winchester to Clifton the next night.

For the cavalry, in this move to the rear, I gave the following
instructions:

"....In pushing up the Shenandoah Valley, as it is expected you will
have to go first or last, it is desirable that nothing should be left
to invite the enemy to return. Take all provisions, forage, and
stock wanted for the use of your command. Such as cannot be
consumed, destroy. It is not desirable that buildings should be
destroyed--they should, rather, be protected; but the people should
be informed that so long as an army can subsist among them,
recurrences of these raids must be expected, and we are determined to
stop them at all hazards...." [Grant's letter of instructions.]
