n, either to watchmen on Lookout Mountain
or Missionary Ridge, until they emerged between the hills to strike the
bank of the river. But when Sherman's advance reached a point opposite
the town of Chattanooga, Howard, who, it will be remembered, had been
concealed behind the hills on the north side, took up his line of march
to join the troops on the south side. His crossing was in full view
both from Missionary Ridge and the top of Lookout, and the enemy of
course supposed these troops to be Sherman's. This enabled Sherman to
get to his assigned position without discovery.

CHAPTER XLIII.

PREPARATIONS FOR BATTLE--THOMAS CARRIES THE FIRST LINE OF THE ENEMY
--SHERMAN CARRIES MISSIONARY RIDGE--BATTLE OF LOOKOUT MOUNTAIN
--GENERAL HOOKER'S FIGHT.

On the 20th, when so much was occurring to discourage--rains falling so
heavily as to delay the passage of troops over the river at Brown's
Ferry and threatening the entire breaking of the bridge; news coming of
a battle raging at Knoxville; of Willcox being threatened by a force
from the east--a letter was received from Bragg which contained these
words: "As there may still be some non-combatants in Chattanooga, I
deem it proper to notify you that prudence would dictate their early
withdrawal." Of course, I understood that this was a device intended to
deceive; but I did not know what the intended deception was. On the
22d, however, a deserter came in who informed me that Bragg was leaving
our front, and on that day Buckner's division was sent to reinforce
Longstreet at Knoxville, and another division started to follow but was
recalled. The object of Bragg's letter, no doubt, was in some way to
detain me until Knoxville could be captured, and his troops there be
returned to Chattanooga.

During the night of the 21st the rest of the pontoon boats, completed,
one hundred and sixteen in all, were carried up to and placed in North
Chickamauga. The material for the roadway over these was deposited out
of view of the enemy within a few hundred yards of the bank of the
Tennessee, where the north end of the bridge was to rest.

Hearing nothing from Burnside, and hearing much of the distress in
Washington on his account, I could no longer defer operations for his
relief. I determined, therefore, to do on the 23d, with the Army of the
Cumberland, what had been intended to be done on the 24th.

The position occupied by the Army of the Cumberland had been made very
strong
