We captured a good many prisoners, among them a whole infantry regiment, the Fourteenth Alabama, three hundred and twenty strong.
On the 16th the general movement was continued, when Lost Mountain was abandoned by the enemy.

Our right naturally swung round, so as to threaten the railroad below Marietta, but Johnston had still further contracted and strengthened his lines, covering Marietta and all the roads below.
On the 17th and 18th the rain again fell in torrents, making army movements impossible, but we devoted the time to strengthening our positions, more especially the left and centre, with a view gradually to draw from the left to add to the right; and we had to hold our lines on the left extremely strong, to guard against a sally from Kenesaw against our depot at Big Shanty.

Garrard's division of cavalry was kept busy on our left, McPherson had gradually extended to his right, enabling Thomas to do the same still farther; but the enemy's position was so very strong, and everywhere it was covered by intrenchments, that we found it as dangerous to assault as a permanent fort.

We in like manner covered our lines of battle by similar works, and even our skirmishers learned to cover their bodies by the simplest and best forms of defensive works, such as rails or logs, piled in the form of a simple lunette, covered on the outside with earth thrown up at night.
The enemy and ourselves used the same form of rifle-trench, varied according to the nature of the ground, viz.: the trees and bushes were cut away for a hundred yards or more in front, serving as an abatis or entanglement; the parapets varied from four to six feet high, the dirt taken from a ditch outside and from a covered way inside, and this parapet was surmounted by a "head-log," composed of the trunk of a tree from twelve to twenty inches at the butt, lying along the interior crest of the parapet and resting in notches cut in other trunks which extended back, forming an inclined plane, in case the head-log should be knocked inward by a cannon-shot.

The men of both armies became extremely skillful in the construction of these works, because each man realized their value and importance to himself, so that it required no orders for their construction.
