When the remainder of the division came up, Captain Reynolds' Battery "L" of the 1st New York Artillery, as already stated, was sent to assist Calef in keeping down the fire of two rebel batteries on the ridge to the west; but when Ewell's artillery also opened, the cross fire became too severe.
Calef was withdrawn, and Reynolds was severely wounded.

The rebel batteries soon after ceased firing for the time being; and at Wadsworth's request, Colonel Wainwright, Chief of Artillery to the First Corps, posted a section of Reynolds' battery, under Lieutenant Wilbur, on Seminary Ridge, south of the railroad cut; Stewart's Battery "B" 4th United States being on a line north of the cut.
Cooper's battery was directed to meet Ewell's attack from the north, and Stevens' 5th Maine battery was retained behind the Seminary in reserve.
Barlow's division on the right and Schimmelpfennig's on the left, formed somewhat hastily against Ewell, whose line of battle faced south.

Barlow rested his right on a wooded knoll, constituting part of the western bank of Rock Creek.

As there was an open country to the east he considered that flank secure, for no enemy was in sight then, and if they came from that direction, there would be time to make fresh dispositions.

After the formation there was an interval of a quarter of a mile between their left and the First Corps, which might have been avoided by placing the two divisions further apart.
