of my reserve brigade, and establishing my headquarters behind the
trunk of a large fallen tree, which would shelter me somewhat from
the cold December wind, lay down beside a small camp-fire to get some
rest.

At 2 o'clock on the morning of the 31st General Sill came back to me
to report that on his front a continuous movement of infantry and
artillery had been going on all night within the Confederate lines,
and that he was convinced that Bragg was massing on our right with
the purpose of making an attack from that direction early in the
morning. After discussing for a few minutes the probabilities of
such a course on the part of the enemy, I thought McCook should be
made acquainted with what was going on, so Sill and I went back to
see him at his headquarters, not far from the Griscom House, where we
found him sleeping on some straw in the angle of a worm-fence. I
waked him up and communicated the intelligence, and our consequent
impressions. He talked the matter over with us for some little time,
but in view of the offensive-defensive part he was to play in the
coming battle, did not seem to think that there was a necessity for
any further dispositions than had already been taken. He said that
he thought Johnson's division would be able to take care of the
right, and seemed confident that the early assault which was to be
made from Rosecrans's left would anticipate and check the designs
which we presaged. We two then returned to my little camp-fire
behind the log, and as we continued talking of what might be expected
from the indications on the right, and Sill becoming more anxious, I
directed two regiments from the reserve to report to him, that they
might be placed within very short supporting distance of his line.
He then rejoined his brigade, better satisfied, but still adhering to
the belief he had expressed when first making his report.
