s. Then, too, it would not have been prudent to proceed without
the gunboats. At least it would have been leaving behind a valuable
part of our available force.

On the 7th, the day after the fall of Fort Henry, I took my staff and
the cavalry--a part of one regiment--and made a reconnoissance to within
about a mile of the outer line of works at Donelson. I had known
General Pillow in Mexico, and judged that with any force, no matter how
small, I could march up to within gunshot of any intrenchments he was
given to hold. I said this to the officers of my staff at the time. I
knew that Floyd was in command, but he was no soldier, and I judged that
he would yield to Pillow's pretensions. I met, as I expected, no
opposition in making the reconnoissance and, besides learning the
topography of the country on the way and around Fort Donelson, found
that there were two roads available for marching; one leading to the
village of Dover, the other to Donelson.

Fort Donelson is two miles north, or down the river, from Dover. The
fort, as it stood in 1861, embraced about one hundred acres of land. On
the east it fronted the Cumberland; to the north it faced Hickman's
creek, a small stream which at that time was deep and wide because of
the back-water from the river; on the south was another small stream, or
rather a ravine, opening into the Cumberland. This also was filled with
back-water from the river. The fort stood on high ground, some of it as
much as a hundred feet above the Cumberland. Strong protection to the
heavy guns in the water batteries had been obtained by cutting away
places for them in the bluff. To the west there was a line of rifle
pits some two miles back from the river at the farthest point. This
line ran generally along the crest of high ground, but in one place
crossed a ravine which opens into the river between the village and the
fort. The ground inside and outside of this intrenched line was very
broken and generally wooded. The trees outside of the rifle-pits had
been cut down for a considerable way out, and had been felled so that
their tops lay outwards from the intrenchments. The limbs had been
trimmed and pointed, and thus formed an abatis in front of the greater
part of the line. Outside of this intrenched line, and extending about
half the entire length of it, is a ravine running north and south and
opening into Hickman creek at a point north of the fort. The entire
side of this r
