[544] heights on the opposite side of the stream, the Confederate commander determined to move across Hatcher's Run at once, and assail Hancock's right. 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.

Most of the troops were disposed so as to meet an attack from quite a different direction, so that the outburst of the enemy was on their rear, and the presence of the Confederates was first announced by volleys of musketry. Peirce's brigade of Mott's division at this point gave way, one section of artillery was captured, and affairs appeared as critical as can well be conceived.

It is probable that the Confederates did not precisely comprehend the situation, for on emerging into the open space around the Boydton plankroad, they pushed rapidly across that road, and, facing southward, commenced firing.
