Twenty days after the battle of Antietam, General Lee had
his army positioned near Bunker Hill, on Opequon Creek. McClellan’s army was
positioned on the left bank of the Potomac from about Harper’s Ferry westward
to Williamsport. Lee’s army was positioned at Bunker Hill on the Opequon.
On October 10th, Lee sent Stuart on a mission of
reconnaissance, the purpose of which was to scout the Cashtown Gap, between Chambersburg and Gettysburg, and the terrain between the east entrance to the gap and Gettysburg. Lee was already thinking of the road net that converged on Gettysburg as the
means of meeting the enemy in an encounter battle.
Stuart, with a cavalry force of about 1,800 men and several
pieces of artillery, went by way of Hedgesville to McCoy’s Ford, where he
crossed the Potomac into Maryland and headed in a roundabout way for
Chambersburg.Along the way, Stuart seized as many horses as he could find,
giving each trooper two, if not three mounts, and went through the Cashtown Gap
into the open country beyond, coming within sight of Gettysburg. Then he turned
south to Fairfield, passed through Emmittsburg and looped down through Maryland to the Potomac. His force traveled about 65 miles in 24 hours. Reaching White’s
Ford, he encountered a regiment of Union troops, raced through them and forded
the river without loss.

The discipline of historians is not geared to fact-finding;
they read an historical document as if it were the final expression of truth.
Rarely do they compare what a witness wrote or said, or is reported to have
said, with what the evidence demonstrates the actors actually did. The
idea that a reasonable person in Lee’s shoes would allow his cavalry commander
to wander off on a lark with 1,800 men and horses, expose them to the exertion
of an exhausting march through enemy territory, for no purpose other than to
burn a bridge or terrorize a town for an hour or so, would never be accepted by
a jury in a courtroom.
The process of trial lawyers, in their presentation of probative
evidence, pro and con, highlighted by their contrary arguments, in persuading
the jury to their respective points of view, ensures that the jury focuses its
deliberation precisely upon what the jurors would expect a reasonable person,
under the circumstances shown by the evidence, would do.
Here General Lee must have had an intelligent military
reason for sending Stuart on such a dangerous mission, for the
danger of being destroyed by McClellan’s pursuit was very real. The only
reasonable explanation, given the known circumstances, and in light of Lee’s
subsequent actions, is that Lee wanted intelligence about the Cashtown Gap
where eventually he intended to place for a number of days over fifty thousand
of his troops, and intelligence about the nature of the ground between Cashtown
and Gettysburg. That ground extends for eight miles. It is rolling farmland.
The perfect ground for a battle, as long as the enemy could be drawn deep into
it. Lee knew he would be drawing his army toward the Rappanhannock as soon as
McClellan began moving, and took advantage of the down time to gain the
intelligence which he would take into consideration in the following months, as
he planned the battle of Gettysburg.
