days supplies left, and
that he must be relieved within that time.

Sherman, fortunately, had not started on his return from Graysville,
having sent out detachments on the railroad which runs from Dalton to
Cleveland and Knoxville to thoroughly destroy that road, and these
troops had not yet returned to camp. I was very loath to send Sherman,
because his men needed rest after their long march from Memphis and hard
fighting at Chattanooga. But I had become satisfied that Burnside would
not be rescued if his relief depended upon General Granger's movements.

Sherman had left his camp on the north side of the Tennessee River, near
Chattanooga, on the night of the 23d, the men having two days' cooked
rations in their haversacks. Expecting to be back in their tents by
that time and to be engaged in battle while out, they took with them
neither overcoats nor blankets. The weather was already cold, and at
night they must have suffered more or less. The two days' rations had
already lasted them five days; and they were now to go through a country
which had been run over so much by Confederate troops that there was but
little probability of finding much food. They did, however, succeed in
capturing some flour. They also found a good deal of bran in some of
the mills, which the men made up into bread; and in this and other ways
they eked out an existence until they could reach Knoxville.

I was so very anxious that Burnside should get news of the steps being
taken for his relief, and thus induce him to hold out a little longer if
it became necessary, that I determined to send a message to him. I
therefore sent a member of my staff, Colonel J. H. Wilson, to get into
Knoxville if he could report to Burnside the situation fully, and give
him all the encouragement possible. Mr. Charles A. Dana was at
Chattanooga during the battle, and had been there even before I assumed
command. Mr. Dana volunteered to accompany Colonel Wilson, and did
accompany him. I put the information of what was being done for the
relief of Knoxville into writing, and directed that in some way or other
it must be secretly managed so as to have a copy of this fall into the
hands of General Longstreet. They made the trip safely; General
Longstreet did learn of Sherman's coming in advance of his reaching
there, and Burnside was prepared to hold out even for a longer time if
it had been necessary.
