n 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.]

"HEADQUARTERS MIDDLE MILITARY DIVISION,
"Cedar Creek, Va., August 16, 1864.

"GENERAL: In compliance with instructions of the Lieutenant-General
commanding, you will make the necessary arrangements and give the
necessary orders for the destruction of the wheat and hay south of a
line from Millwood to Winchester and Petticoat Gap. You will seize
all mules, horses, and cattle that may be useful to our army. Loyal
citizens can bring in their claims against the Government for this
necessary destruction. No houses will be burned, and officers in
charge of this delicate but necessary duty must inform the people
that the object is to make this valley untenable for the raiding
parties of the rebel army.

"Very respectfully,

"P. H. SHERIDAN,
"Major-General Commanding.

During his visit to General Hunter at the Monocacy, General Grant had
not only decided to retain in the Shenandoah Valley a large force
sufficient to defeat Early's army or drive it back to Lee, but he had
furthermore determined to make that sections by the destruction of
