valry next morning, before Lee could get his forces
back, to destroy fifteen or twenty miles of the Weldon Railroad. But
misfortunes never come singly. I learned during that same afternoon
that Wright's pursuit of Early was feeble because of the constant and
contrary orders he had been receiving from Washington, while I was cut
off from immediate communication by reason of our cable across
Chesapeake Bay being broken. Early, however, was not aware of the fact
that Wright was not pursuing until he had reached Strasburg. Finding
that he was not pursued he turned back to Winchester, where Crook was
stationed with a small force, and drove him out. He then pushed north
until he had reached the Potomac, then he sent McCausland across to
Chambersburg, Pa., to destroy that town. Chambersburg was a purely
defenceless town with no garrison whatever, and no fortifications; yet
McCausland, under Early's orders, burned the place and left about three
hundred families houseless. This occurred on the 30th of July. I
rescinded my orders for the troops to go out to destroy the Weldon
Railroad, and directed them to embark for Washington City. After
burning Chambersburg McCausland retreated, pursued by our cavalry,
towards Cumberland. They were met and defeated by General Kelley and
driven into Virginia.

The Shenandoah Valley was very important to the Confederates, because it
was the principal storehouse they now had for feeding their armies about
Richmond. It was well known that they would make a desperate struggle
to maintain it. It had been the source of a great deal of trouble to us
heretofore to guard that outlet to the north, partly because of the
incompetency of some of the commanders, but chiefly because of
interference from Washington.

It seemed to be the policy of General Halleck and Secretary Stanton to
keep any force sent there, in pursuit of the invading army, moving right
and left so as to keep between the enemy and our capital; and, generally
speaking, they pursued this policy until all knowledge of the
whereabouts of the enemy was lost. They were left, therefore, free to
supply themselves with horses, beef cattle, and such provisions as they
could carry away from Western Maryland and Pennsylvania. I determined
to put a stop to this. I started Sheridan at once for that field of
operation, and on the following day sent another division of his
cavalry.

I had previously asked to have Sheridan assigned to tha
