Sherman came up, having reached Graysville with his
troops, where he found Palmer had preceded him. Palmer had picked up
many prisoners and much abandoned property on the route. I went back in
the evening to Graysville with Sherman, remained there over night and
did not return to Chattanooga until the following night, the 29th. I
then found that Thomas had not yet started Granger, thus having lost a
full day which I deemed of so much importance in determining the fate of
Knoxville. Thomas and Granger were aware that on the 23d of the month
Burnside had telegraphed that his supplies would last for ten or twelve
days and during that time he could hold out against Longstreet, but if
not relieved within the time indicated he would be obliged to surrender
or attempt to retreat. To effect a retreat would have been an
impossibility. He was already very low in ammunition, and with an army
pursuing he would not have been able to gather supplies.

Finding that Granger had not only not started but was very reluctant to
go, he having decided for himself that it was a very bad move to make, I
sent word to General Sherman of the situation and directed him to march
to the relief of Knoxville. I also gave him the problem that we had to
solve--that Burnside had now but four to six 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
