Hill accordingly crossed, and, as it happened, his point of passage brought him directly in the interval between Hancock and Crawford. But of this circumstance he was not at all aware, owing to the densely wooded character of the country. The Confederate infantry passed close to Crawford's skirmishers, and followed a path through the woods until they were near Hancock's position, when they deployed, and, about four P.
