For the next five weeks the operations on my part consisted
almost wholly of offensive and defensive manoeuvring for certain
advantages, the enemy confining himself meanwhile to measures
intended to counteract my designs. Upon the advent of Torbert, Early
immediately grew suspicious, and fell back twelve miles south of
Martinsburg, to Bunker Hill and vicinity, where his right flank would
be less exposed, but from which position he could continue to
maintain the break in the Baltimore and Ohio railroad, and push
reconnoitring parties through Smithfield to Charlestown. These
reconnoitring parties exhibited considerable boldness at times, but
since they had no purpose in view save to discover whether or not we
were moving, I did not contest any ground with them except about our
outposts. Indeed, I desired that Early might remain at some point
well to the north till I was fully prepared to throw my army on his
right and rear and force a battle, and hence I abstained from
disturbing him by premature activity, for I thought that if I could
beat him at Winchester, or north of it, there would be far greater
chances of weighty results. I therefore determined to bring my
troops, if it were at all possible to do so, into such a position
near that town as to oblige Early to fight. The sequel proved,
however, that he was accurately informed of all my movements. To
anticipate them, therefore, he began his retreat up the valley the
day that I moved out from Halltown, and consequently was able to
place himself south of Winchester before I could get there.

For a clear understanding of the operations which preceded the
victories that resulted in almost annihilating General Early's army
in the Shenandoah Valley, it is necessary to describe in considerable
detail the events that took place prior to the 19th of September. My
army marched from Harper's Ferry on the 10th of August, 1864, General
Torbert with Merritt's division of cavalry moving in advance through
Berryville, going into position near White Post. The Sixth Corps,
under General Wright, moved by way of Charlestown and Summit Point
