People from outside began to pour into Richmond to help eat up the little on hand.

Consternation reigned there.
On the 12th Smith was ordered to move at night to White House, not to stop until he reached there, and to take boats at once for City Point, leaving his trains and artillery to move by land.
Soon after dark some of the cavalry at Long Bridge effected a crossing by wading and floundering through the water and mud, leaving their horses behind, and drove away the cavalry pickets.

A pontoon bridge was speedily thrown across, over which the remainder of the army soon passed and pushed out for a mile or two to watch and detain any advance that might be made from the other side.

Warren followed the cavalry, and by the morning of the 13th had his whole corps over.

Hancock followed Warren.
