ter to quit the service before the close of the war.

Gregg's fight fully satisfied me that we could not get the trains up
to the pontoon-bridge, for of course Hampton would now throw all his
cavalry in my front, on the river road, where it could be backed up
by Lee's infantry. Meanwhile, General Meade had become assured of
the same thing, and as he was now growing anxious about the fate of
Wilson's division--which, during my absence, had been sent out to
break the enemy's communications south of Petersburg, by destroying
the Southside and Danville railroads--he sent ferryboats to cross me
over the James. During the night of the 24th, and next morning, the
immense train--which ought never to have been left for the cavalry to
escort, after a fatiguing expedition of three weeks--was moved back
through Charles City Court House to Douthard's landing, and there
ferried over the river, followed by my troops in like manner. When
General Hampton discovered this, he moved to Drury's Bluff, and
there, on the morning of the 27th, crossed the James by the
Confederate pontoon-bridge.

While I was absent on the expedition to Trevillian, the movement of
the Army of the Potomac across the James River was effected, and
Wilson, whom I had left behind for the purpose, was engaged in the
duty of covering its front and rear. Late on the night of June 12
he, with Chapman's brigade, crossed the Chickahominy at Long Bridge,
in advance of the Fifth Corps, and by 7 o'clock next morning had
driven the enemy's pickets up to White Oak bridge, where he waited
for our infantry. When that came up, he pushed on as far as Riddle's
Shop, but late that evening the Confederate infantry forced him to
withdraw to St. Mary's Church; for early in the morning General Lee
had discovered the movement of our army, and promptly threw this
column of infantry south of the Chickahominy to White Oak Swamp, with
the design of covering Richmond. From St. Mary's Church Wilson
guarded all the roads toward White Oak Swamp and Riddle's Shop,
McIntosh's brigade joining him on the 14th, by way of Long Bridge, as
the rear of the Army of the Potomac passed the Chickahominy. In the
performance of this duty Wi
