July 26th, when the 2d Corps and the Cavalry crossed the James River
to Deep Bottom, for the purpose of drawing some of Lee's forces to the
North side of the James, pending the Explosion of the Mine which had
been worked in front of the 9th Corps, commencing on June 25th, and was
now ready to be fired.
On the 29th, the 2d Corps was brought back to the James, and crossed
over at night, with orders to proceed to that part of the line where
the Mine was located.
