s before the campaign opened.

The interview also disclosed the fact that the cavalry commander
should be, according to General Meade's views, at his headquarters
practically as one of his staff, through whom he would give detailed
directions as, in his judgment, occasion required. Meade's ideas and
mine being so widely divergent, disagreements arose between us later
during the battles of the Wilderness, which lack of concord ended in
some concessions on his part after the movement toward Spottsylvania
Court House began, and although I doubt that his convictions were
ever wholly changed, yet from that date on, in the organization of
the Army of the Potomac, the cavalry corps became more of a compact
body, with the same privileges and responsibilities that attached to
the other corps--conditions that never actually existed before.

On the 4th of May the Army of the Potomac moved against Lee, who was
occupying a defensive position on the south bank of the Rapidan.
After detailing the various detachments which I was obliged to supply
for escorts and other mounted duty, I crossed the river with an
effective force of about 10,000 troopers. In the interval succeeding
my assignment to the command of the cavalry, I had taken the pains to
study carefully the topography of the country in eastern Virginia,
and felt convinced that, under the policy Meade intended I should
follow, there would be little opportunity for mounted troops to
acquit themselves well in a region so thickly wooded, and traversed
by so many almost parallel streams; but conscious that he would be
compelled sooner or later either to change his mind or partially give
way to the pressure of events, I entered on the campaign with the
loyal determination to aid zealously in all its plans.

General Lee's army was located in its winter quarters behind
intrenchments that lay along the Rapidan for a distance of about
twenty miles; extending from Barnett's to Morton's ford. The fords
below Morton's were watched by a few small detachments of Confederate
cavalry, the main body of which, however, was encamped below
Hamilton's crossing, where it could draw supplies from the rich
country along the Rappahannock. Only a few brigades of Lee's
infantry guarded the works along the river, the bulk of it being so
situated that it could be thrown to either flank toward which the
Union troops approached.

General Grant adopted the plan of moving by his left flank, with the
pu
