termining to content himself
with Wright's corps, directed Emory to stay where he was. Emory
now had 253 officers and 5,320 men for duty.

As one turn of the wheel had given the Nineteenth Corps to Butler,
restoring to his command some of the regiments that had gone with
him to the capture of New Orleans, so the next turn was to bring
the corps under Augur, who since leaving Louisiana had been in
command of the department of Washington. So at least run the orders
of the 23d of July, yet hardly had Emory reported his division to
Augur, when the whole arrangement was suddenly broken up, and the
army that had just marched back to Washington with Wright was once
more hurried off to meet what was supposed to be a fresh invasion
by Early. In fact Early was quietly reposing at Bunker Hill, where
he easily commanded the approaches and debouches of the Shenandoah
valley, the fords of the Potomac, from Harper's Ferry to Williamsport,
and the whole line of the railway across the great bend of the
Potomac.

By this time Grant had found out that it often took twenty-four
hours to communicate with Washington by telegraph, and that it was
consequently impossible to control from the James the movements of
his forces on the upper Potomac. On his suggesting this, the
government confided to Halleck the direction of Wright's operations
against Early. The Sixth Corps marched from Tennallytown on the
morning of the 26th of July, and immediately afterwards the Nineteenth
Corps broke up its camp near the chain bridge and followed the
Sixth. The line of march followed the road to Rockville, where
Wright divided the column, sending a detachment to the left by way
of Poolesville, while the main body pursued the direct road towards
Frederick. Emory encamped that night on the Frederick road, four
miles north of Rockville, after a march of nineteen miles. The
next day, the 27th of July, Emory, leading the column, marched at
three in the morning, moved fifteen miles, and encamped beyond
Hyattstown. On the 28th Emory took the road at five, marched to
Monocacy Junction, where the Sixth Corps crossed the Monocacy, then
filed to the right, and crossed at the upper ford, and passing
through Frederick went into bivouac four miles beyond. The distance
made was thirteen miles. On the 29th, an intensely hot day, Emory
marched at eight, following the Sixth Corps, crossed the Potomac
at Harper's Ferry, marched nineteen miles, and went into bivouac
