s strange that he did not, even before receiving his
reinforcements, turn on McCook in Broomtown Valley and destroy him.

Intelligence that Bragg would give battle began to come to us from
various sources as early as the 10th of September, and on the 11th
McCook found that he could not communicate with Thomas by the direct
road through Broomtown Valley; but we did not begin closing in toward
Chattanooga till the 13th, and even then the Twentieth Corps had
before it the certainty of many delays that must necessarily result
from the circuitous and difficult mountain roads which we would be
obliged to follow. Had the different corps, beginning with McCook's,
been drawn in toward Chattanooga between the 8th and 12th of
September, the objective point of the campaign would have remained in
our hands without the battle of Chickamauga, but, as has been seen,
this was not done. McCook was almost constantly on the march day and
night between the 13th and the 19th, ascending and descending
mountains, his men worried and wearied, so that when they appeared on
the battle-field, their fatigued condition operated greatly against
their efficiency. This delay in concentration was also the original
cause of the continuous shifting toward our left to the support of
Thomas, by which manoeuvre Rosecrans endeavored to protect his
communications with Chattanooga, and out of which grew the intervals
that offered such tempting opportunities to Bragg. In addition to
all this, much transpired on the field of battle tending to bring
about disaster. There did not seem to be any well-defined plan of
action in the fighting; and this led to much independence of judgment
in construing orders among some of the subordinate generals. It also
gave rise to much license in issuing orders: too many people were
giving important directions, affecting the whole army, without
authority from its head. In view, therefore, of all the errors that
were committed from the time Chattanooga fell into our hands after
our first crossing the Tennessee, it was fortunate that the Union
defeat was not more complete, that it left in the enemy's possession
not much more than the barren results arising from the simple holding
of the ground on which the engagement was fought.
