theory that he wished to adopt it when at last it lay open. On the
contrary, he continued his advance precisely as before. On May 16 his
leading columns reached White House; headquarters were established
there, and steps were immediately taken to utilize it as a depot and
base of supplies. The York River route was thus made the definitive
choice. Also the advance divisions were immediately pushed out along
the York River and Richmond Railroad, which they repaired as they went.
On May 20 Casey's division actually crossed the Chickahominy at Bottom's
Bridge, and the next day a large part of the army was in position upon
the north bank of that stream. Obviously these operations, each and all,
ruled out the James River route, at least as a part of the present plan.
Yet it was not until they were well under way, viz., on May 18, that the
intelligence reached McClellan, on the strength of which he and others
afterward assumed that he had been deprived of the power to select the
James River route. What this intelligence was and how it came to pass
must now be narrated.

By this time, the advance along the Peninsula had so completely
"relieved the front of Washington from pressure," that Mr. Lincoln and
his advisers, reassured as to the safety of that city, now saw their way

capital; also, with a decisive emphasis indicative of an uneasy
suspicion, McClellan was forbidden to dispose of McDowell's force in
