Again there was a momentary belief that Marietta was abandoned, but again it was premature, for the apex of the angle was stoutly held at the rocky crest of Kennesaw. [Footnote: _Id_., p. 519.] There was nothing for it but to continue the swing of the right flank. In his instructions to Thomas, Sherman said, "Until Schofield develops the flank we should move with due caution; but the moment it is found or we are satisfied the enemy has lengthened his line beyond his ability to defend, we must strike quick and with great energy." [Footnote: _Id_., p. 509.] The waters were up in all the streams, and Noyes's was wholly unfordable. Following the Sandtown road southward, my division was stopped by the creek, and the enemy's artillery and dismounted cavalry held a good position on the other side, having removed the flooring of the bridge. In a brilliant little affair by a part of Cameron's brigade, the bridge was carried, and the whole division was soon across and intrenched at the crest on the south side, covering the intersection of the Sandtown road with that from Marietta to Powder Springs Church. [Footnote: Official Records, vol. xxxviiii. pt. iv. pp. 534, 540.] On the morning of June 22d, the rest of Schofield's corps crossed the creek and took the Marietta road, whilst Hooker's corps swung forward from the right of the Cumberland Army to keep pace with Schofield. My own division at the same time marched southward on the Sandtown road to Cheney's farm, near the crossing of Olley's Creek, the next in the series of parallel valleys trending to the southwest. Cheney's was also at the crossing of the lower road from Marietta to Powder Springs village, which forked near Kolb's farm, the northern branch being that on which Schofield was advancing with Hascall's division. But Hood's corps was also upon this road, having marched in the night from the extreme right of Johnston's army to extend the left and meet our aggressive movement. This brought on the bloody affair of Kolb's (or Culp's) farm, Hood making a fierce attack on Schofield's left and Hooker's right, which was repulsed. [Footnote: Atlanta, p. 108, etc.] The enemy had to content himself with extending southward the line confronting ours, till it passed over the ridge behind Noyes's creek and covered the valley of Olley's. Schofield had called me with three brigades to Hascall's support, leaving one (Reilly's) at the Cheney farm. [Footnote: Official Records, vol. xxxviii. pt. iv. pp. 558, 559, 566-569.]
