:

Enclosed herewith I send you copy of instructions to
Major-General Thomas. You having been over the ground in
person, and having heard the whole matter discussed, further
instructions will not be necessary for you. It is particularly
desirable that a force should be got through to the railroad
between Cleveland and Dalton, and Longstreet thus cut off from
communication with the South, but being confronted by a large
force here, strongly located, it is not easy to tell how this is
to be effected until the result of our first effort is known.

I will add, however, what is not shown in my instructions to
Thomas, that a brigade of cavalry has been ordered here which,
if it arrives in time, will be thrown across the Tennessee above
Chickamauga, and may be able to make the trip to Cleveland or
thereabouts.

CHATTANOOGA, November 18, 1863.

MAJOR-GENERAL GEO. H. THOMAS,
Chattanooga:

All preparations should be made for attacking the enemy's
position on Missionary Ridge by Saturday at daylight. Not being
provided with a map giving names of roads, spurs of the
mountains, and other places, such definite instructions cannot
be given as might be desirable. However, the general plan, you
understand, is for Sherman, with the force brought with him
strengthened by a division from your command, to effect a
crossing of the Tennessee River just below the mouth of
Chickamauga; his crossing to be protected by artillery from the
heights on the north bank of the river (to be located by your
chief of artillery), and to secure the heights on the northern
extremity to about the railroad tunnel before the enemy can
concentrate against him. You will co-operate with Sherman. The
troops in Chattanooga Valley should be well concentrated on your
left flank, leaving only the necessary force to defend
fortifications on the right and centre, and a movable column of
one division in readiness to move wherever ordered. This
division should show itself as threateningly as possible on the
most practicable line for making an attack up the valley. Your
effort then will be to form a junction with Sherman, making your
advance well towards the northern end of Missionary Ridge, and
moving as near simultaneously with him as possible. The
junction once formed and the ridge carried, communications will
be at once established between the two armies by roads on the
south bank of the river. Further movements will then
