Strips of water a few hundred feet wide often nullify the plans for entire armies. In this photograph is one of the pontoon-bridges across the James, at Powhatan Point, near Harrison's Landing, which was used by part of General Grant's army in the march from Cold Harbor to Petersburg.

The view here is southwest and note the upstream pontoon bridge, with several Union soldiers lounging, thereupon. Note the mill dam and mill pool, with Tom Stubblefield's grist mill on the left. The officer on horseback probably belongs to the 50th New York Engineers, as that worthy outfit's camp was situated just to the north of this spot.
