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 the 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.

"Bear in mind, the object is to drive the enemy south; and to do this
you want to keep him always in sight. Be guided in your course by
the course he takes.

"Make your own arrangements for supplies of all kinds, giving regular
vouchers for such as may be taken from loyal citizens in the country
through which you march.

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

the control of the active forces of his command, but because he
thought that his fitness for the position he was filling was
distrusted by General Halleck, and he had no wish to cause
embarrassment by remaining where he could but remove me one degree

request was complied with, and an order was issued by the President,
consolidating the Middle Department, the Department of Washington,
the Department of the Susquehanna, and the Department of West
Virginia.

Under this order these four geographical districts constituted the
Middle Military Division, and I was temporarily assigned to command
it. Hunter's men had been bivouacking for some days past in the
vicinity of Monocacy Junction and Frederick, but before General
Grant's instructions were written out, Hunter had conformed to them
by directing the concentration at Halltown, about four miles in front
of Harper's Ferry, of all his force available for field service.
Therefore the different bodies of troops, with the exception of
Averell's cavalry, which had followed McCausland toward Moorefield
after the burning of Chambersburg, were all in motion toward Halltown
on August 6.

Affairs at Monocacy kept me but an hour or two, and these disposed
of, I continued on to Harper's Ferry by the special train which had
brought
