und, 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. As soon as a regiment or brigade gained a
position within easy distance for a sally, it would set to work
with a will, and would construct such a parapet in a single night;
but I endeavored to spare the soldiers this hard labor by
authorizing each division commander to organize out of the freedmen
who escaped to us a pioneer corps of two hundred men, who were fed
out of the regular army supplies, and I promised them ten dollars a
month, under an existing act of Congress. These pioneer
detachments became very useful to us during the rest of the war,
for they could work at night while our men slept; they in turn were
not expected to fight, and could therefore sleep by day. Our
enemies used their slaves for a similar purpose, but usually kept
them out of the range of fire by employing them to fortify and
strengthen the position to their rear next to be occupied in their
general retrograde. During this campaign hundreds if not thousands
of miles of similar intrenchments were built by both armies, and,
as a rule, whichever party attacked got the worst of it.
On the 19th of June the rebel army again fell back on its flanks,
to such an extent that for a time I supposed it had retreated to
the Chattahoochee River, fifteen miles distant; but as we pressed
forward we were soon undeceived, for we found it still more
concentrated, covering Marietta and the railroad. These successive
contractions of the enemy's line encouraged us and discouraged him,
but were doubtless justified by sound reasons. On the 20th
Johnston's position was unusually strong. Kenesaw Mountain was his
salient; his two flanks were refused and covered by parapets and by
Noonday and Nose's Creeks. His
