The Fifth Corps had marched to Kelley's Ford, and crossed in rear of the
Twelfth Corps. From here, Sykes's and Griffin's divisions marched
towards Ely's Ford, preceded by Col. Devin's Sixth New York Cavalry,
which surprised the pickets at that place. The troops crossed by
wading. Humphreys remained behind to cover the passage of the trains,

On crossing the Rapidan, Sykes was pushed towards United-States Ford,
to dislodge the Confederate force there, by thus taking in reverse their

A skirmish of no particular moment had occurred between Griffin and
Anderson, as the former reached Chancellorsville. Anderson had been
retiring before the Federal advance, on the plank road towards
Fredericksburg. His rear guard made a short stand at the crossroads,
but withdrew after a few rounds; and Anderson took up a position near
Mine Road, where numerous ravines, perpendicular to the river, afforded
excellent successive lines of defence.

On reaching Chancellorsville, Slocum took command of the three corps
there assembled. He was ordered to ascertain, by a cavalry party,

Banks's Ford to be secured. If the enemy were in strong force, Slocum
was to select a position, and compel his attack. Not a moment was to be
lost until the troops were concentrated at Chancellorsville. "From that
