bridges were naturally destroyed before the National troops came to
them.

The Army of the Potomac was composed of three infantry and one cavalry
corps, commanded respectively by Generals W. S. Hancock, G. K. Warren,
(*27) John Sedgwick and P. H. Sheridan. The artillery was commanded by
General Henry J. Hunt. This arm was in such abundance that the fourth
of it could not be used to advantage in such a country as we were
destined to pass through. The surplus was much in the way, taking up as
it did so much of the narrow and bad roads, and consuming so much of the
forage and other stores brought up by the trains.

The 5th corps, General Warren commanding, was in advance on the right,
and marched directly for Germania Ford, preceded by one division of
cavalry, under General J. H. Wilson. General Sedgwick followed Warren
with the 6th corps. Germania Ford was nine or ten miles below the right
of Lee's line. Hancock, with the 2d corps, moved by another road,
farther east, directly upon Ely's Ford, six miles below Germania,
preceded by Gregg's division of cavalry, and followed by the artillery.
Torbert's division of cavalry was left north of the Rapidan, for the
time, to picket the river and prevent the enemy from crossing and
getting into our rear. The cavalry seized the two crossings before
daylight, drove the enemy's pickets guarding them away, and by six
o'clock A.M. had the pontoons laid ready for the crossing of the
infantry and artillery. This was undoubtedly a surprise to Lee. The
fact that the movement was unopposed proves this.

Burnside, with the 9th corps, was left back at Warrenton, guarding the
railroad from Bull Run forward to preserve control of it in case our
crossing the Rapidan should be long delayed. He was instructed, however,
to advance at once on receiving notice that the army had crossed; and a
dispatch was sent to him a little after one P.M. giving the information
that our crossing had been successful.

The country was heavily wooded at all the points of crossing,
particularly on the south side of the river. The battle-field from the
crossing of the Rapidan until the final movement from the Wilderness
toward Spottsylvania was of the same character. There were some
clearings and small farms within what might be termed the battle-field;
but generally the country was covered with a dense forest. The roads
were narrow and bad. All the conditions were favorabl
